Hi there.
This is my first trip with RadControls. I've created an usercontrol, which shows a Grid. My datasource is a DataTable, wich is populated on NeedDataSource event. I have to dynamically generate all columns of DataTable at runtime, so my ASCX file is pretty poor:
Also i need to group data. Therefore, i add columnbound on codebehind. Here is the important part of NeedDataSource
All works fine and the output is really pretty. But if i collapse one group, all column headers will be lost. I've also implemented export to Excel and PDF. It generates a file, but there are much more columns and some values are System.Data.DataRowView. Maybe it's the same reason?
Please advise me. Thanks
