I'm using the following method to export a radgrid report to Excel:
and in the codebehind:
I'm trying to insert a custom header at the top of the report with a few rows of contextual data from codebehind. I've seen some samples for html and biff, but not xlsx format. I can adjust a few things like row height in the InfrastructureExporting method, but I can't figure out if it's possible to insert rows and add text to them. Any help greatly appreciated.
