I work with Excel Interop, I try to get color of rows from specyfic Table Style.
I get name of Table Style like that:
var TableStyle = table.TableStyle.Name.ToString();
But I haven't got idea how get colors from known style.
I soloved my problem.
If somebody will have similar in the future.
You can access to table in that way:
var tse = table.TableStyle.TableStyleElements;
double rs1 = ((TableStyleElement)tse[5]).Interior.Color;
double rs2 = ((TableStyleElement)tse[6]).Interior.Color;
when indexes of tse is an enum:

But If you need create new style, you should copy existing and edit.

In my rdlc report have following columns
SlNo, Item, Uom, Qty, Rate, Amount
Here the Amount field is a formula (Rate*Qty)
The report is working fine, and when i export to excel also displaying the values are correctly.
But my problem is, after export to excel, when i change the Qty or Rate columns in excel file the Amount is not get changed automatically, because the formula is missing in the excel cell.
How can we include the formula in Amount column while export to excel from .rdlc?
I'm afraid that this required behaviour isn't really possible by just using the rdlc rendering.
In my search I stumbled upon this same link that QHarr posted: https://social.msdn.microsoft.com/Forums/en-US/3ddf11bf-e10f-4a3e-bd6a-d666eacb5ce4/report-viewer-export-ms-report-data-to-excel-with-formula?forum=vsreportcontrols
I haven't tried the project that they're suggesting but this might possibly be your best solution if it works. Unfortunately I do not have the time to test it myself, so if you test this please share your results.
I thought of the following workaround that seems to work most of the times, but isn't really that reliable because the formula sometimes gets displayed as full-text instead of being calculated. But I guess this could be solved by editing the excel file just after being exported, and changing the cell properties of this column containing the formula or just triggering the calculate.
Using the built-in-field Globals!RenderFormat.Name you can determine the render mode, this way you can display the result correctly when the report is being rendered to something different than Excel. When you export to Excel, you could change the value of the cell to the actual formula.
To form the formula it's self you'll need to figure this out on your own, but the RowNumber(Scope as String) function can be of use here to determine the row number of your cells.
Here is a possible example for the expression value of your amount column
=IIF(Globals!RenderFormat.Name LIKE "EXCEL*", "=E" & Cstr(RowNumber("DataSet1")+2) & "*F" & Cstr(RowNumber("DataSet1")+2) ,Fields!Rate.Value * Fields!Qty.Value )
Now considering that this formula sometimes gets displayed as full-text, and you'll probably have to edit the file post-rendering. If it's too complicated to determine which row/column the cell is on, you could also do this post-rendering. But I believe that the above expression should be easy enough to use to get your desired result without having to do much after rendering.
Update: The following code could be used to force the calculation of the formula (post rendering)
var fpath = #"C:\MyReport.xlsx";
using (var fs = File.Create(fpath))
{
var lr = new LocalReport();
//Initializing your reporter
lr.ReportEmbeddedResource = "MyReport.rdlc";
//Rendering to excel
var fbytes = lr.Render("Excel");
fs.Write(fbytes, 0, fbytes.Length);
}
var xlApp = new Microsoft.Office.Interop.Excel.Application() { Visible = false };
var wb = xlApp.Workbooks.Open(fpath);
var ws = wb.Worksheets[1];
var range = ws.UsedRange;
foreach (var cell in range.Cells)
{
var cellv = cell.Text as string;
if (!string.IsNullOrWhiteSpace(cellv) && cellv.StartsWith("="))
{
cell.Formula = cellv;
}
}
wb.Save();
wb.Close(0);
xlApp.Quit();
I am trying to export a report to excel. When I export my report to Excel I am getting blank rows between each detail section. I assume this is because I have a context menu in form of a normal text element which overlies the "normal" text elements.
Does anybody have any advice on how I can stop the blank rows occurring? Is it possible to suppress a text element only when it is exported to Excel?
Thanks!
Try to make it compact.
It should be no space between each object. You should set every object on the same row has the same height and every object on column has the same width.
When there's a space between objects, it will create a cell on excel.
There are 2 articles from Ken Hamady that might be helpfull:

Another option , if you are working with tabular data is to use a report extension like it is shown in this video: https://www.youtube.com/watch?v=3hk6FJ1dvb4
This approach will use the Crystal report as a datasource and will export the data from a grid with much better formatting. The video is using a 3rd party tool, but it is free - http://www.r-tag.com/Pages/CommunityEdition.aspx
Use This Code:
Public Shared Sub ExportDataSetToExcel(ByVal ds As DataTable, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response
response.Clear()
response.Buffer = True
response.Charset = ""
response.ContentType = "application/vnd.ms-excel"
Using sw As New StringWriter()
Using htw As New HtmlTextWriter(sw)
Dim dg As New DataGrid()
dg.DataSource = ds
dg.DataBind()
dg.RenderControl(htw)
response.Charset = "UTF-8"
response.ContentEncoding = System.Text.Encoding.UTF8
response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble())
response.Output.Write(sw.ToString())
response.[End]()
End Using
End Using
End Sub
Finally I've solved this issue, after a long time researching. Make the fields inside the details section fill the whole height of the section... no spaces between fields and top and bottom edges.
instead of this
simple question but I can't seem to find an answer anywhere so I'll put it here: how to you assign table styles to tables, yet not map it to a default table style i.e. make custom style elements? I read it might involve .TableStyleElements but when I tried to add ActiveSheet.ListObjects("Table1").TableStyleElements(xlHeaderRow).Font.Color = RGB(119, 184, 0) it breaks. Am I getting the syntax wrong?
I believe you need to declare the table style first eg:
Dim oTblStyle As TableStyle
Set oTblStyle = ActiveSheet.ListObjects("Table1").TableStyle
oTblStyle.TableStyleElements.Item(xlHeaderRow).Font.Color = RGB(119, 184, 0)
I'm trying to change values of an excel workbook using Update but something is wrong i.e. y want to get the value from table B and put it in table a
my code is this, can you help me?
UPDATE [Data$]
SET A.[D ArtN] = B.[D ArtC]
FROM [Datos$] as A
INNER JOIN [Productos$] as B
ON A.[Art] = B.[ArtC]
UPDATE [Data$]
SET [Data$].[D ArtN] = [Productos$].[D ArtC]
WHERE [Data$].[Art] = [Productos$].[ArtC]
Is the correct format of an update statement. I'm not sure that this is the correct SQL syntax, as you did not specify if what you were using in Excel.

I have used automation to insert values into a cell, however I have never seen any documentation, for example, that demonstrate inserting anything other than text and/or formula's.
Has anybody been able to insert an image from an external application?
Dim FileName as string
FileName="c:\text.jpg"
Set NewPic = ActiveSheet.Pictures.Insert(FileName)
NewPic.top=100
NewPic.left=100
If you want to position the picture to a specific cell then select that cell as a range and use that ranges top/left/with to position the picture.
Samples: http://exceltip.com/st/Insert_pictures_using_VBA_in_Microsoft_Excel/486.html
Note: In Excel cells cannot contain pictures. The pictures live on an invisible drawing layer that floats about the cells. They can be positioned based on the cell coordinates, which makes it feel like they are living "in" the cells.
I see it's already been answered, but see my post here.
Basically rather than use the Worksheet.Pictures.Insert method (which the MSDN recommends you don't use directly, and which returns a raw COM object), try the Worksheet.Shapes.AddPicture method instead.
Dim range As Microsoft.Office.Interop.Excel.Range
Dim pic as Microsoft.Office.Interop.Excel.Shape
Dim filePath as String
range = ...
filePath = ...
pic = range.Worksheet.Shapes.AddPicture(filePath, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue, range.Left, range.Top, 300, 300)
It's not quite as straightforward because you have to specify the exact position and dimensions, but otherwise, pretty cool!
Sure, the following code gives a good example using the Microsoft Interop libraries:
string excelfilename = #"C:\excelfile.xlsx";
string picturename = #"C:\image.jpg";
object missing = Type.Missing;
Microsoft.Office.Interop.Excel.Application app = new ApplicationClass();
Workbook book = app.Workbooks.Add(missing);
Worksheet sheet = (Worksheet)book.ActiveSheet;
Pictures pics = (Pictures)sheet.Pictures(missing);
pics.Insert(picturename, missing);
book.SaveAs(excelfilename, missing, missing, missing, missing, missing, XlSaveAsAccessMode.xlNoChange,
missing, missing, missing, missing, missing);
app.Quit();
app = null;
