I have a radgrid on my aspx page. I build the grid/columns dynamically in the code behind. I use the NeedDataSource to populate the data and then use the ExportToExcel command to export the grid. I cannot find how to either wrap the column headers and/or format my numeric columns with commas. Below is the code and the aspx page and code-behind. Please help on how to do both.
A button on my page calls the exportSummary() function.
