RadGrid collapse group crash using DataTable - Possible bug?

[Ben]

Hello!

I had an issue which would cause exceptions when I attempted to collapse a group within a RadGrid. (Clicking the little ^)
This issue seemed to stem from the fact I had set the RadGrid datasource to a DataTable. After setting the RadGrid DataSource to an SQLDataSource I had no more exceptions and everything collapsed nicely. :)

I was retrieving the innitial DataTable during Page_Init and then setting RadGrid datasource to the DataTable.
Once I switched to using an SQLDataSource I set the SelectCommand of the SQLDataSource during Page_Init.

Was I doing something wrong and managed to indirectly fix it by using an SQLDataSource? Or is this a possible bug within the Telerik software?

Thanks,
Ben.

Hello Ben,

I tried to reproduce the issue locally but without success. Would you mind opening a formal support ticket and sending me a sample demo page?

Looking forward to your reply.
