Hi priya,
Here is the code. Thanks. Also if you can also remove the white space in each cell following strings, it would be great.

Hello York,

I also faced the same issue when I tried to export the Radgrid with footer and autogenerated button columns. This issue arises when exported excel file contains any AutoGeneratedEditColumn/DeleteColumn and when "ShowFooter" property is set to true. Try the following code snippet to hide these before exporting to excel.

C#:

protected void button1_Click(object sender, EventArgs e)

{

RadGrid1.ExportSettings.ExportOnlyData = true;

RadGrid1.MasterTableView.ShowFooter = false;

RadGrid1.MasterTableView.GetColumn("AutoGeneratedEditColumn").Visible = false;

RadGrid1.MasterTableView.ExportToExcel();

}

Thanks,
Princy.
