New to MVC and having some trouble with what should be simple. I'm trying to return a dataset to just an Excel spreadsheet without any real UI.
Here's my code (cannibalized from a few sources):
Controller code:
public ActionResult GetCommissionsExcel(string agencyid, string month, string year)
{
try
{
var as400rep = new iSeriesRepository(new iSeriesContext());
var results = as400rep.GetCommissionExcel(agencyid, month, year);
string xml = String.Empty;
XmlDocument xmlDoc = new XmlDocument();
XmlSerializer xmlSerializer = new XmlSerializer(results.GetType());
using (System.IO.MemoryStream xmlStream = new System.IO.MemoryStream())
{
xmlSerializer.Serialize(xmlStream, results);
xmlStream.Position = 0;
xmlDoc.Load(xmlStream);
xml = xmlDoc.InnerXml;
}
var fName = string.Format("CommissionsExcelExport-{0}", DateTime.Now.ToString("s"));
byte[] fileContents = System.Text.Encoding.UTF8.GetBytes(xml);
return File(fileContents, "application/vnd.ms-excel", fName);
}
catch (Exception ex)
{
Log.Error(ex.Message, ex.InnerException);
throw;
}
}
The jQuery call:
function getExcelExport() {
var activePane = $('div.tab-pane.active');
var agencyCompany = $(activePane).find('#Agency_AgencyId').val();
var month = $(activePane).find('#CommissionMonth').val();
var year = $(activePane).find('#CommissionYear').val();
var url = '#Url.Content("~")' + 'AgencyManagement/GetCommissionsExcel';
window.location = 'AgencyManagement/GetCommissionsExcel';
//$.post('#Url.Action("GetCommissionsExcel", "AgencyManagement")' , {agencyid: agencyCompany, month: month, year: year});
};
It pulls back the data, but I can't figure out how to get it to pop from the search window. It looks like the window.location line makes the call, but I need to post the parameters to the call and that's where I'm stuck.
Figured it out. Just needed to call the jQuery as follows:
window.location = 'AgencyManagement/GetCommissionsExcel?agencyID=' + agencyCompany + '&month=' + month + '&year=' + year;
And I needed to append ".xls" to the filename in the controller action.
var fName = string.Format("CommissionsExcelExport-{0}", DateTime.Now.ToString("s"));
fName = fName + ".xls";
Worked like a charm

I try to create folder in sharepoint online, based on some of tutorial. the problem comes since creating folder is not given "Title" column value.
I want to create folder and also update column "Title".
here is the code for create folder
public string CreateDocumentLibrary(string siteUrl, string relativePath)
{
//bool responseResult = false;
string resultUpdate = string.Empty;
string responseResult = string.Empty;
if (siteUrl != _siteUrl)
{
_siteUrl = siteUrl;
Uri spSite = new Uri(siteUrl);
_spo = SpoAuthUtility.Create(spSite, _username, WebUtility.HtmlEncode(_password), false);
}
string odataQuery = "_api/web/folders";
byte[] content = ASCIIEncoding.ASCII.GetBytes(#"{ '__metadata': { 'type': 'SP.Folder' }, 'ServerRelativeUrl': '" + relativePath + "'}");
string digest = _spo.GetRequestDigest();
Uri url = new Uri(String.Format("{0}/{1}", _spo.SiteUrl, odataQuery));
// Set X-RequestDigest
var webRequest = (HttpWebRequest)HttpWebRequest.Create(url);
webRequest.Headers.Add("X-RequestDigest", digest);
// Send a json odata request to SPO rest services to fetch all list items for the list.
byte[] result = HttpHelper.SendODataJsonRequest(
url,
"POST", // reading data from SP through the rest api usually uses the GET verb
content,
webRequest,
_spo // pass in the helper object that allows us to make authenticated calls to SPO rest services
);
string response = Encoding.UTF8.GetString(result, 0, result.Length);
if (response != null)
{
//responseResult = true;
responseResult = response;
}
return responseResult;
}
I already tried to use CAML, but, the problem is, the list of sharepoint is big, so got the error prohibited access related to limit tresshold.
Please help.
Refer below code to update folder name.
function renameFolder(webUrl,listTitle,itemId,name)
{
var itemUrl = webUrl + "/_api/Web/Lists/GetByTitle('" + listTitle + "')/Items(" + itemId + ")";
var itemPayload = {};
itemPayload['__metadata'] = {'type': getItemTypeForListName(listTitle)};
itemPayload['Title'] = name;
itemPayload['FileLeafRef'] = name;
var additionalHeaders = {};
additionalHeaders["X-HTTP-Method"] = "MERGE";
additionalHeaders["If-Match"] = "*";
return executeJson(itemUrl,"POST",additionalHeaders,itemPayload);
}
function getItemTypeForListName(name) {
return"SP.Data." + name.charAt(0).toUpperCase() + name.slice(1) + "ListItem";
}
I'm trying to generate an excel file / stream in my web api and return it in a HttpResponseMessage to serve it to the client in Angular 5 as a download.
The generation succeeds and an xlsx file is generated and saved on the server, but when I return it in the Content of my httpResponseMessage, my browser shows just some json instead of the whole excel file.
{"version":{"major":1,"minor":1,"build":-1,"revision":-1,"majorRevision":-1,"minorRevision":-1},"content":{"headers":[{"key":"Content-Disposition","value":["attachment; filename=636742856488421817.xlsx"]},{"key":"Content-Type","value":["application/ms-excel"]},{"key":"Content-Length","value":["22780"]}]},"statusCode":200,"reasonPhrase":"OK","headers":[],"requestMessage":null,"isSuccessStatusCode":true}
This is how I create the excel file and returns it:
var dataBytes = File.ReadAllBytes(fileName);
var dataStream = new MemoryStream(dataBytes);
HttpResponseMessage httpResponseMessage = new HttpResponseMessage(HttpStatusCode.OK);
httpResponseMessage.Content = new StreamContent(dataStream);
httpResponseMessage.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
httpResponseMessage.Content.Headers.ContentDisposition.FileName = fileName;
httpResponseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("application/ms-excel");
httpResponseMessage.Content.Headers.ContentLength = dataStream.Length;
I solved this:
Here is what I did
Helper class which creates the excel package and converts it to a Stream
var fileName = DateTime.Now.Ticks + ".xlsx";
FileInfo file = new FileInfo(fileName);
FileInfo templateFile = new FileInfo(#"Templates/ReportTemplate.xlsx");
ExcelPackage package = new ExcelPackage(file, templateFile);
ExcelWorksheet worksheet = package.Workbook.Worksheets.FirstOrDefault();
... filling rows and cells goed here ...
var dataBytes = package.GetAsByteArray();
Stream dataStream = new MemoryStream(dataBytes);
dataStream.Seek(0, SeekOrigin.Begin);
return dataStream;
In the controller I return the file to the Angular client like this:
var stream = _helperClass.GenerateReport(exportDate, exportTitle);
return File(stream, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", $"Report-{DateTime.Now.ToShortDateString()}.xlsx");
In the Angular component I do this after I receive the response:
var blob = new Blob([res], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
var blobURL = window.URL.createObjectURL(blob);
var anchor = document.createElement("a");
anchor.download = `Report-${new Date().toISOString()}.xlsx`;
anchor.href = blobURL;
anchor.click();
Try this following code:
For conroller:
[Route("DownLoadExcel")]
public IActionResult DownLoadExcel()
{
var pack = new ExcelPackage();
ExcelWorksheet worksheet = pack.Workbook.Worksheets.Add("sample");
//First add the headers
worksheet.Cells[1, 1].Value = "ID";
worksheet.Cells[1, 2].Value = "Name";
//Add values
worksheet.Cells["A2"].Value = 1000;
worksheet.Cells["B2"].Value = "Jon";
return File(pack.GetAsByteArray(), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "Sample.xlsx");
}
For client side:
window.open("../.../DownLoadExcel");
First I need to explain my problem, I have a native query application where someone types in "Select .... this and that" and the output is currently displayed in a grid that is paginated and I have been asked to add a button that will export the data to excel directly from an untyped datastream. my current code that I've found uses a grid and still doesn't prompt me to download a .xls file for some reason.
[Authorize(Roles = "Portal administrator")]
public void ExportExcel(NativeQueryVM model, int? page, string sort)
{
List<Dictionary<string, object>> result = null;
String vartimedate = DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss");
try
{
var user = Membership.GetUser();
var grid = new System.Web.UI.WebControls.GridView();
if (page == null && sort == null)
{
if (model.QueryText.ToUpper().StartsWith("SELECT"))
{
UserQueryInput queryinput = new UserQueryInput();
queryinput.DatabaseId = model.selectedDatabase;
queryinput.QueryText = model.QueryText;
result = lookupProvider.GetSetNativeQuery((Guid)user.ProviderUserKey, user.UserName, queryinput, "Set");
model.QueryResultData = result;
ViewBag.SubmitType = "Select";
CreateDynamicResult(model.QueryResultData);
if (model == null || model.QueryResultData.Count == 0)
{
ViewBag.ResultMessage = "No Results Found";
}
else
{
WebGrid wd = new WebGrid(source: ViewBag.DynamicResult, canPage: false, canSort: false );
string griddata = wd.GetHtml().ToString();
string attachment = "attachment; filename=NativeQuery" + vartimedate + ".xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
Response.Write(griddata);
Response.End();
}
}
}
else
{ //This part should come when page or sort is not null for Select. Should not be executed other than SELECT
result = lookupProvider.GetSetNativeQuery((Guid)user.ProviderUserKey, user.UserName, null, "Get");
model.QueryResultData = result;
ViewBag.SubmitType = "Select";
CreateDynamicResult(model.QueryResultData);
if (model == null || model.QueryResultData.Count == 0)
{
ViewBag.ResultMessage = "No Results Found";
}
else
{
}
}
}
catch (Exception ex)
{
logger.Log(new LogMessage()
.ForMethod("SubmitQuery")
.WithContext(Environment.MachineName)
.WithException(ex)
.WithDescription("An error occurred while submiting query to get result"));
}
}
Hi all that answered this problem, and I've found the answer and issues reside outside of the code that I've entered into the question. Jquery was intercepting the output of my file stream and on the other hand, if the button was created with runat=server the model is out of scope and the main part of the solution involved saving the model to a session and pulling it back in.
Thanks for your assistance all...
How are you calling this void function? The return paths include setting a ViewBag property with an error message along with modifying the response. It smells of bad design.
I'd create a hyperlink that links to a #Url.Action for something like this. Note that you'd need to return a FileContentResult with the data UTF8-encoded rather than modifying the Response directly:
public async Task<ActionResult> Test()
{
WebGrid wd = new WebGrid(source: ViewBag.DynamicResult, canPage: false, canSort: false );
string griddata = wd.GetHtml().ToString();
string attachment = "attachment; filename=NativeQuery" + vartimedate + ".xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/excel";
byte[] buffer = System.Text.UTF8Encoding.UTF8.GetBytes(griddata);
return File(buffer, "application/octet-stream");
}
I am using Rotativa to generate PDF in my "MVC" application. How can I save Rotativa PDF? I need to save the document on a server after all the process is completed.
Code below:
public ActionResult PRVRequestPdf(string refnum,string emid)
{
var prv = functions.getprvrequest(refnum, emid);
return View(prv);
}
public ActionResult PDFPRVRequest()
{
var prv = Session["PRV"] as PRVRequestModel;
byte[] pdfByteArray = Rotativa.WkhtmltopdfDriver.ConvertHtml("Rotativa", "Approver", "PRVRequestPdf");
return new Rotativa.ViewAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno });
}
You can give this a try
var actionResult = new ActionAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno, emid = "Whatever this is" });
var byteArray = actionResult.BuildPdf(ControllerContext);
var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write);
fileStream.Write(byteArray, 0, byteArray.Length);
fileStream.Close();
If that doesn't do the trick then, you can follow the answers here
Just make sure if you do it this way not to have PRVRequestPdf return as a PDF View, rather a normal View like you have above (only mention as managed to fall foul of that myself causing lots of fun).
Another useful answer:
I found the solution here
var actionPDF = new Rotativa.ActionAsPdf("YOUR_ACTION_Method", new { id = ID, lang = strLang } //some route values)
{
//FileName = "TestView.pdf",
PageSize = Size.A4,
PageOrientation = Rotativa.Options.Orientation.Landscape,
PageMargins = { Left = 1, Right = 1 }
};
byte[] applicationPDFData = actionPDF.BuildPdf(ControllerContext);
This is the original thread
You can achieve this with ViewAsPdf.
[HttpGet]
public ActionResult SaveAsPdf(string refnum, string emid)
{
try
{
var prv = functions.getprvrequest(refnum, emid);
ViewAsPdf pdf = new Rotativa.ViewAsPdf("PRVRequestPdf", prv)
{
FileName = "Test.pdf",
CustomSwitches = "--page-offset 0 --footer-center [page] --footer-font-size 8"
};
byte[] pdfData = pdf.BuildFile(ControllerContext);
string fullPath = #"\\server\network\path\pdfs\" + pdf.FileName;
using (var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write))
{
fileStream.Write(pdfData, 0, pdfData.Length);
}
return Json(new { isSuccessful = true }, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
//TODO: ADD LOGGING
return Json(new { isSuccessful = false, error = "Uh oh!" }, JsonRequestBehavior.AllowGet);
//throw;
}
}
You can simply try this:
var fileName = string.Format("my_file_{0}.pdf", id);
var path = Server.MapPath("~/App_Data/" + fileName);
System.IO.File.WriteAllBytes(path, pdfByteArray );
Being very new to SharePoint coding I have been assigned the task to create a prototype code to upload a file and setting the field values for that file that will show up when opening the sharepoint page with the file.
This has to be done from a remote machine and not the Sharepoint server itself so using the .Net objects for Sharepoint is out the question.
I quickly found out how to upload a file through the Sharepoint Web Service Copy.asmx:
void UploadTestFile() {
var file = #"C:\Temp\TestFile.doc";
string destinationUrl = "http://mysharepointserver/Documents/"
+ Path.GetFileName(file);
string[] destinationUrls = { destinationUrl };
var CopyWS = new Copy.Copy();
CopyWS.UseDefaultCredentials = true;
CopyWS.Url = "http://mysharepointserver/_vti_bin/copy.asmx";
CopyResult[] result;
byte[] data = File.ReadAllBytes(file);
FieldInformation mf1 = new FieldInformation {
DisplayName = "title",
InternalName = "title",
Type = FieldType.Text,
Value = "Dummy text"
};
FieldInformation mf2 = new FieldInformation {
DisplayName = "MyTermSet",
InternalName = "MyTermSet",
Type = FieldType.Note,
Value = "Test; Unit;"
};
CopyWS.CopyIntoItems(
"+",
destinationUrls,
new FieldInformation[] { mf1, mf2 },
data,
out result);
}
This code easily uploads any file to the target site but only fills the "title" field with info. The field MyTermSet in which I have added 3 terms allready - Test, Unit and Page - will not update with the values "Test;" and "Unit;".
Being very new to Sharepoint and me not grasping all the basics googling has told me that updating "File", "Computed" or "Lookup" fields does not work with the CopyIntoItems method, and MyTermSet being a Taxonomy field is - if I am correct - a Lookup field.
So how do I get MyTermSet updated with the values "Test;" and "Unit;" ?
I would really prefer If someone has a sample code on this. I have followed several hint-links but I am none the wiser. I have found no sample-code on this at all.
Have anyone made one single method that wraps it all? Or another method that takes in the destinationUrl from the file upload and updates the Term Set/Taxonomy field.
Puzzling together what I have found so far, I am now able to do as I wanted. But I would really like to be able to get the Taxonomy field GUIDs dynamically and NOT having to explicitly set them myself:
void UploadTestFile(string FileName, string DocLib, Dictionary<string, string> Fields = null) {
//Upload the file to the target Sharepoint doc lib
string destinationUrl = DocLib + Path.GetFileName(FileName);
string[] destinationUrls = { destinationUrl };
var CopyWS = new Copy.Copy();
CopyWS.UseDefaultCredentials = true;
CopyWS.Url = new Uri(new Uri(DocLib), "/_vti_bin/copy.asmx").ToString();
CopyResult[] result;
var data = File.ReadAllBytes(FileName);
CopyWS.CopyIntoItems(
"+",
destinationUrls,
new FieldInformation[0],
data,
out result);
if (Fields == null) return; //Done uploading
//Get the ID and metadata information of the fields
var list = new ListsWS.Lists();
list.UseDefaultCredentials = true;
var localpath = new Uri(DocLib).LocalPath.TrimEnd('/');
var site = localpath.Substring(0, localpath.LastIndexOf("/")); //Get the site of the URL
list.Url = new Uri(new Uri(DocLib), site + "/_vti_bin/lists.asmx").ToString(); //Lists on the right site
FieldInformation[] fiOut;
byte[] filedata;
var get = CopyWS.GetItem(destinationUrl, out fiOut, out filedata);
if (data.Length != filedata.Length) throw new Exception("Failed on uploading the document.");
//Dictionary on name and display name
var fieldInfos = fiOut.ToDictionary(x => x.InternalName, x => x);
var fieldInfosByName = new Dictionary<string, FieldInformation>();
foreach (var item in fiOut) {
if (!fieldInfosByName.ContainsKey(item.DisplayName)) {
fieldInfosByName.Add(item.DisplayName, item);
}
}
//Update the document with fielddata - this one can be extended for more than Text and Note fields.
if (!fieldInfos.ContainsKey("ID")) throw new Exception("Could not get the ID of the upload.");
var ID = fieldInfos["ID"].Value; //The ID of the document we just uploaded
XDocument doc = new XDocument(); //Creating XML with updates we need
doc.Add(XElement.Parse("<Batch OnError='Continue' ListVersion='1' ViewName=''/>"));
doc.Element("Batch").Add(XElement.Parse("<Method ID='1' Cmd='Update'/>"));
var methNode = doc.Element("Batch").Element("Method");
//Add ID
var fNode = new XElement("Field");
fNode.SetAttributeValue("Name", "ID");
fNode.Value = ID;
methNode.Add(fNode);
//Loop each field and add each Field
foreach (var field in Fields) {
//Get the field object from name or display name
FieldInformation fi = null;
if (fieldInfos.ContainsKey(field.Key)) {
fi = fieldInfos[field.Key];
}
else if (fieldInfosByName.ContainsKey(field.Key)) {
fi = fieldInfosByName[field.Key];
}
if (fi != null) {
//Fix for taxonomy fields - find the correct field to update
if (fi.Type == FieldType.Invalid && fieldInfos.ContainsKey(field.Key + "TaxHTField0")) {
fi = fieldInfos[field.Key + "TaxHTField0"];
}
else if (fi.Type == FieldType.Invalid && fieldInfosByName.ContainsKey(field.Key + "_0")) {
fi = fieldInfosByName[field.Key + "_0"];
}
fNode = new XElement("Field");
fNode.SetAttributeValue("Name", fi.InternalName);
switch (fi.Type) {
case FieldType.Lookup:
fNode.Value = "-1;#" + field.Value;
break;
case FieldType.Choice:
case FieldType.Text:
fNode.Value = field.Value;
break;
case FieldType.Note: //TermSet's
var termsetval = "";
var terms = field.Value.Split(';');
foreach (var term in terms) {
termsetval += "-1;#" + term + ";";
}
fNode.Value = termsetval.TrimEnd(';');
break;
default:
//..Unhandled type. Implement if needed.
break;
}
methNode.Add(fNode); //Adds the field to the XML
}
else {
//Field does not exist. No use in uploading.
}
}
//Gets the listname (not sure if it is the full path or just the folder name)
var listname = new Uri(DocLib).LocalPath;
var listcol = list.GetListCollection(); //Get the lists of the site
listname = (from XmlNode x
in listcol.ChildNodes
where x.Attributes["DefaultViewUrl"].InnerText.StartsWith(listname, StringComparison.InvariantCultureIgnoreCase)
select x.Attributes["ID"].InnerText).DefaultIfEmpty(listname).First();
//Convert the XML to XmlNode and upload the data
var xmldoc = new XmlDocument();
xmldoc.LoadXml(doc.ToString());
list.UpdateListItems(listname, xmldoc.DocumentElement);
}
Then I call it like this:
var fields = new Dictionary<string, string>();
fields.Add("Test", "Dummy Text");
fields.Add("MrTermSet", "Page|a4ba29c1-3ed5-47e9-b43f-36bc59c0ea5c;Unit|4237dfbe-22a2-4d90-bd08-09f4a8dd0ada");
UploadTestFile(#"C:\Temp\TestFile2.doc", #"http://mysharepointserver/Documents/", fields);
I would however prefer to call it like this:
var fields = new Dictionary<string, string>();
fields.Add("Test", "Dummy Text");
fields.Add("MrTermSet", "Page;Unit");
UploadTestFile(#"C:\Temp\TestFile2.doc", #"http://mysharepointserver/Documents/", fields);
