I am having a problem with the RadGrid using Multiple Columns when I Bind a DataSource to the RadGrid. Firstly let me show some screenshots of what I am trying to do.
This is an example from Teleriks website under demos and the multiple columns (summary column) is what I am trying to achieve
This is the exception I am getting when I try and bind the control to a DataSource
This is the RadGrid I have set up in my ASP page.
Firstly I don't want to bind the datasource in my asp page. Secondly I wanted the "Product" and "Other" ColumnGroups to be used only as a Summary column and not to be bound to a datasource since these ColumnGroups are only used as headers for the other Columns.
Is there a workaround to not allow the ColumnGroups not to be bound to a DataSource while the normal columns are?
