I have a RadGrid that I want to export to Excel, but above the exported grid I would like to add an addition HTML table. After adding the table, the formatting of the export is unaligned. I'm guessing I don't have my HTML tags correct. All I want to accomplish is adding an HTML table above the exported grid and the table & the grid should fill 100% of the width of the screen. Please help.

Dudeman:

The problem is that when you add HTML as part of the string that you pass to the "dg.MasterTableView.Caption" setting, you are corrupting the ordering of the HTML tags automatically produced by the export function. In order to have MSExcel interpret and correctly render the RadGrid's export, there cannot be any added HTML tags in the stream.

This works for me:

Protected Sub btn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn.Click

Dim header As New StringBuilder("The Title")

dg.MasterTableView.Caption = header.ToString

dg.ExportSettings.ExportOnlyData = True

dg.ExportSettings.OpenInNewWindow = True

dg.ExportSettings.IgnorePaging = True

dg.MasterTableView.ExportToExcel()

End Sub

Hope this helps.
