Grid crashes when group footers and column aggregation is enabled on the server

[Dasha]

Dear Support,

Is there a way to reproduce this example (http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/groupfooter/defaultcs.aspx) by applying all the settings in the code rather than declarаtively in the html?  I may be doing something wrong, but everything works fine until I set CWGrid.MasterTableView.ShowGroupFooter =true, and then the whole page blows up. The screenshot is attached.

Hi Dasha,

You can certainly build the grid programmatically:

Hope it helps.

My grid is declared statically, and the structure is created in the OnLoad event.  The example you referred to creates the whole grid dynamically in the OnInit, and I'm familiar with that example.  Do you have any ideas why the page may be blowing up?

Hello Dasha,

I suspect you have a problem similar to the one described in the following forum thread:

Tsvetoslav,

I've seen that thread while conducting my research, at first I thought it would work, but I'm not even setting the DataType on my columns.  Do you think I need to? I tried both ways, the grid keeps crashing... Could it be because the Aggregate function is count, and the column is Title, which is a string?

If you are using a <telerik:GridBoundColumn> try using a  <telerik:GridNumericColumn> that worked for me.
