I am creating a document set programatically on buttom click event
public void btnCreateDocumentSet_Click(object sender, EventArgs e)
{
try
{
lblError.Text = string.Empty;
SPSecurity.RunWithElevatedPrivileges(() =>
{
using (web = SPControl.GetContextSite(Context).RootWeb)
{
web.AllowUnsafeUpdates = true;
String url = web.Lists[" Tracker"].RootFolder.ServerRelativeUrl.ToString();
SPList list = web.Lists["Tracker"];
Hashtable props = new Hashtable();
props.Add("Number", "item1");
props.Add("Type", "item2");
DocumentSet ds = DocumentSet.Create(list.RootFolder, "NewDocumentSet3", web.ContentTypes["MydocumentSet2"].Id, props, true);
//test
//web.Dispose();
}
}
);
}
catch (SPException ex)
{
lblError.Text = ex.Message;
}
}
I am not getting any exceptions.On button click i am redirected to an error like the following
However the document set named NewDocumentSet3 is created in document library but it looks like a folder(the icon i mean) . when i go to document library->documents tab->New Document I am not getting the document set type .Kindly advise me on this issue.
Thanks in advance
First of all, turn off custom errors, like the screenshots tells you.
Then replace your catch of SPException with a catch of all Exceptions.
Even better yet, test code like this in a separate console app, not right inside handlers.
Look up some resources on the internet on how to debug SharePoint applications. A breakpoint will get you a long way in this particluar situation.
I am very wary of your list called "[space]Tracker". Looks suspicious to me.
Try adding
props.Add("HTML_x0020_File_x0020_Type", "SharePoint.DocumentSet");
to the properties hashset that gest passed in to DocumentSet.Create method.

I am trying to update custom metadata for a document when document is added to the library using item updated event, but it is not working. A custom aspx application is using a href element to point to the URL of the document. Click it on it opens windows explorer view similar to the one that is OOB sharepoint 2013 explorer view. Now when user copy the document from library1(says lives in site1 in sitecollection1) to library2(lives in site2 in sitecollection2) via copy-paste option, I need to clear some of the metadata of the document. I am trying the Lukasz's suggestion for it, but the metadata is not clearing. In the debug mode, even though event firing is disabled before update, I see the updated event is being called again one more time which is strange. At the end, my metadata is not being cleared. I tried with both updating and updated event. Any idea? here is my code for updated:
public override void ItemUpdated(SPItemEventProperties properties)
{
base.ItemUpdated(properties);
ClearNotes(properties);
}
private void ClearNotes(SPItemEventProperties properties)
{
try
{
SPListItem listItem = properties.ListItem;
listItem["Notes1"] = string.Empty;
listItem["ReviewNote"] = null;
base.EventFiringEnabled = false;
listItem.Update();
}
catch (Exception ex)
{
//logging error to db
}
finally
{
base.EventFiringEnabled = true;
}
}
I think it must be this.EventFiringEnable = false;
Not base. ...
You can also do it with itemupdating and Afterproperties, then you dont need to disable the EventFiring and need no update:
public override void ItemUpdating(SPItemEventProperties properties)
{
base.ItemUpdating(properties);
///...
properties.AfterProperties["Notes1"] = string.Empty;
}
EDIT: I've realized that my approach in the second code block was unnecessary. I could accomplish the same thing by doing the following in ItemUpdated:
SPListItem thisItem = properties.ListItem;
thisItem.File.CheckOut();
thisItem["Facility Number"] = "12345";
thisItem.Update();
thisItem.File.CheckIn("force check in");
Unfortunately, I'm still getting the same error message when "thisItem.Update();" is executed: he sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request
I actually was receiving the error above when deploying my sandbox solution originally and used this link (http://blogs.msdn.com/b/sharepointdev/archive/2011/02/08/error-the-sandboxed-code-execution-request-was-refused-because-the-sandboxed-code-host-service-was-too-busy-to-handle-the-request.aspx) to fix it.
I am trying to write a C# event receiver that changes the value of a field when a document is added/changed in a library. I have tried using the following code:
public override void ItemUpdating(SPItemEventProperties properties)
{
base.ItemUpdating(properties);
string fieldInternalName = properties.List.Fields["Facility Number"].InternalName;
properties.AfterProperties[fieldInternalName] = "12345";
}
Unfortunately, this is only working for certain fields. For example, if I replaced "Facility Number" with "Source", the code will execute properly. This may be the fact that we are using a third party software (called KnowledgeLake) that replaces the default edit form in SharePoint with a Silverlight form. Anyway, because I was having challenges with the code above (again, because I think the Silverlight form may be overriding the field after the ItemUpdating event fires), I have tried the following code:
public override void ItemUpdated(SPItemEventProperties properties)
{
base.ItemUpdated(properties);
//get the current item
SPListItem thisItem = properties.ListItem;
string fieldName = "Facility Number";
string fieldInternalName = properties.List.Fields[fieldName].InternalName;
string fieldValue = (string)thisItem["Facility Number"];
if (!String.IsNullOrEmpty(fieldValue))
{
//properties.AfterProperties[fieldInternalName] = "123456789";
SPWeb oWebsite = properties.Web as SPWeb;
SPListItemCollection oList = oWebsite.Lists[properties.ListTitle].Items;
SPListItem newItem = oList.GetItemById(thisItem.ID);
newItem.File.CheckOut();
thisItem[fieldInternalName] = "12345";
thisItem.Update();
newItem.File.CheckIn("force");
}
}
First off, the above seems a little klunky to me as I would love to just use the AfterProperties method. Additionally, I am getting the following error when "newItem.Update()" is executed: he sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request
Am I missing something here? I would love to utilize the first code block. Any help would be appreciated.
Josh was able to answer his own question, which helped me fix my problem as well. Here is a working code snippit.
public override void ItemUpdated(SPItemEventProperties properties)
{
string internalName = properties.ListItem.Fields[columnToUpdate].InternalName;
//Turn off event firing during item update
base.EventFiringEnabled = false;
SPListItem item = properties.ListItem;
item[internalName] = newVal;
item.Update();
//Turn back on event firing
base.EventFiringEnabled = true;
base.ItemUpdated(properties);
}
I am new to sharepoint development and i have task in hand to do. I need to add few lines of code for the following logic.
Need to check if previous title and new title of task items are same.
If Not, then query the Task list
Find all the items which contain the previous title
Update their titles.
Here is my Pseudocode:
public override void ItemUpdating(SPItemEventProperties properties)
{
try {
this.DisableEventFiring();
//Need to write my logic here
base.ItemUpdating(properties);
}
catch (Exception ex) {
}
finally {
this.EnableEventFiring();
}
}
Can somebody guide me how to write the code for the above mentioned logic? If you have any sample code's with similar logic, please share it. It will be helpful for me.
Thanks in Advance!
This code might help you out. Maybe you need to adapt it for your needs, but the properties you need to access are the same.
public override void ItemUpdating(SPItemEventProperties properties)
{
//this will get your title before updating
var oldName = properties.ListItem["Title"].ToString();
//and this will get the new title
var newName = properties.AfterProperties["Title"].ToString();
if (newName != oldName)
{
using (var site = new SPSite("http://yoursitename"))
using (var web = site.OpenWeb())
{
var list = web.Lists["Tasks"];
var items = list.Items.OfType<SPListItem>().Where(i => (string) i["Title"] == oldName);
foreach (var item in items)
{
item["Title"] = newName;
item.Update();
}
}
}
base.ItemUpdating(properties);
}
I've got the following problem:
I created a WebPart with a ToolPart,
this toolpart has multiple controls (textbox, dropdownlist, ...)
when I fill in everything and apply, it all goes ok,
even when i press ok. But when i go back to
edit -> modify webpart, all my data i've entered is gone.
How can i solve this?
Thanks
You'll need to save the values from the Toolpart in the webpart's properties. For example, lets say I want to save a string for "Title"... in the webpart define a property:
private const string DEFAULT_WPPColumnTitle = "Title";
private string _WPPColumnTitle = DEFAULT_WPPColumnTitle;
[Browsable(false)]
[WebPartStorage(Storage.Shared)]
public string WPPColumnTitle
{
get { return this._WPPColumnTitle; }
set { this._WPPColumnTitle = value; }
}
I always use the prefix "WPP" to keep all the web part properties together.
Then, in the Toolpart's ApplyChanges override, save the control's value (_ddlColumnsTitle) to the webpart (WPPColumnTitle):
/// <summary>
/// Called by the tool pane to apply property changes to
/// the selected Web Part.
/// </summary>
public override void ApplyChanges()
{
// get our webpart and set it's properties
MyCustomWebPart et = (MyCustomWebPart)ParentToolPane.SelectedWebPart;
et.WPPColumnTitle = _ddlColumnsTitle.SelectedValue;
}
Lastly, if the user edited the properties already, we want the Toolpart to be pre-populated with the user's configuration. In the CreateChildControls() method of your Toolpart, initialize the controls:
protected override void CreateChildControls()
{
try
{
MyCustomWebPart et = (MyCustomWebPart)ParentToolPane.SelectedWebPart;
// ... code to create _ddlColumnsTitle and add it to the Controls
// default our dropdown to the user's selection
ListItem currentItem = _ddlColumnsTitle.Items.FindByValue(et.WPPColumnTitle);
if (null != currentItem)
{
_ddlColumnsTitle.SelectedValue = currentItem.Value;
}
}
catch (Exception ex)
{
_errorMessage = "Error adding edit controls. " + ex.ToString();
}
}
Open up the debugger and double check that the values are getting applied to your propertries on Apply (i.e. WPPColumnTitle is set).
If so then problem is that SharePoint is not serializing/deserializing the value from the property (WPPColumnTitle) to the database and back - verify by writing out this property on the web part - as soon as you leave the page and come back it will be empty.
If so then check things like this on class
[XmlRoot(Namespace = "YourNamespace")]
and this (not strictly necessary) on properties
[XmlElement(ElementName = "ColumnTitle")]
I've also seen problems if you name your web part class "WebPart" so call it MyWebPart
I've solved it with adding a property in my webpart "IsNeverSet" (bool)
and when i go to the "CreateControls()" of my toolpart, I get this property
and if it's false, I load all the properties from my webpart and fill them in the toolpart.
So I found it with the help of Kit Menke
I developed an outlook add in (custom task pane), with web browser in the user control.
All the things working well beside the backspace or the delete button when I am writing something in text box in the web browser, I can't use those keys, am I missing something?
I am a few years late to the party but I managed to fix this. The easiest way to fix this is to ensure proper focus is given to the input fields, so you will need to be able to run your own javascript on whatever page is being loaded.
The javascript I run on the page is as follows (using jQuery):
$(document).on("click", function (e) {
// first let the add-in give focus to our CustomTaskPane
window.external.focus();
// then in our web browser give focus to whatever element was clicked on
$(e.target).focus();
});
the window.external variable contains code run from the plugin (c# or VB I assume) which is exposed so we can interact from web page back to the add-in.
In the add-in code for the custom taskpane set the context of window.external:
// event when webBrowser is finished loading document
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
// sets context of window.external to functions defined on this context
webBrowser1.ObjectForScripting = this;
}
And a public method for focusing:
// can be called by the web browser as window.external.focus()
public void focus()
{
this.Focus();
}
This worked for me, and I hope it helps others. Although do note that this probably doesn't work if the user keyboard navigates using tab, but you can either extend this code for that use case, or safely assume that the average outlook user will have his hand glued to the mouse.
Ok I solved the problem ,
The problem is that the custom task pane in not always gets fucos from the outlook.
So, I raised an event every time that there is "onclick" for all the pane, and then forced the pane to be in focus.
spent a lot of time trying to get this working in Outlook v16.0.13801.20288 the above did not work for me. I ended up with this working code.
Create a user control and add your webbrowser control to it then customize the .cs as below
private void CreateTaskPane() {
MyWinFormUserControl webBrowser = new MyWinFormUserControl();
webBrowser.webBrowser3.Url = new Uri("https://google.com");
webBrowser.webBrowser3.Width = 500;
webBrowser.webBrowser3.Dock = DockStyle.Fill;
webBrowser.webBrowser3.Visible = true;
webBrowser.Width = 500;
webBrowser.Dock = DockStyle.Fill;
webBrowser.Visible = true;
this.CRMTaskPaneControl = CustomTaskPanes.Add(webBrowser, "My App");
//Components.WebViewContainerWPFUserControl webView = (Components.WebViewContainerWPFUserControl)_eh.Child;
//webView.webview.Source = new Uri("https://localhost:3000");
this.CRMTaskPaneControl.Width = 500;
System.Windows.Forms.Application.DoEvents();
this.CRMTaskPaneControl.Control.Focus();
this.CRMTaskPane.Visible = true;
}
public partial class MyWinFormUserControl : UserControl
{
public WebBrowser webBrowser3;
public System.Windows.Forms.WebBrowser webBrowser1;
public MyWinFormUserControl()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.webBrowser3 = new System.Windows.Forms.WebBrowser();
this.SuspendLayout();
//
// webBrowser3
//
this.webBrowser3.Dock = System.Windows.Forms.DockStyle.Fill;
this.webBrowser3.Location = new System.Drawing.Point(0, 0);
this.webBrowser3.MinimumSize = new System.Drawing.Size(20, 20);
this.webBrowser3.Name = "webBrowser3";
this.webBrowser3.Size = new System.Drawing.Size(500, 749);
this.webBrowser3.TabIndex = 0;
this.webBrowser3.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(this.webBrowser3_DocumentCompleted);
//
// MyWinFormUserControl
//
this.Controls.Add(this.webBrowser3);
this.Name = "MyWinFormUserControl";
this.Size = new System.Drawing.Size(500, 749);
this.Load += new System.EventHandler(this.MyWinFormUserControl_Load);
this.ResumeLayout(false);
}
void webBrowser3_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
HtmlDocument doc;
doc = webBrowser3.Document;
doc.Click += doc_Click;
}
void doc_Click(object sender, HtmlElementEventArgs e)
{
this.Focus(); // force user control to have the focus
HtmlElement elem = webBrowser3.Document.GetElementFromPoint(e.ClientMousePosition);
elem.Focus(); // then let the clicked control to have focus
}
private void MyWinFormUserControl_Load(object sender, EventArgs e)
{
//Control loaded
}
Turns out this is an easy issue to fix.
Just write
class MyBrowser : WebBrowser {}
Then use MyBrowser instead of the .NET one.
