[Solved] RadGrid, TemplateColumns destroys entire grid

[Bilal]

hi guys,

I am trapped in a weird problem. My grid works like charm but destroys the entire table structure right after I introduce a TemplateColumn or a NestedViewTemplate.



Please review attachment.



Any idea how to fix it?

telerik:RadGrid ID="radGrid" DataSourceID="sdcReq"

I just figured out that OnNeedDataSource was the culprit for all disruptions with GridTemplateColumn.

I am still engaged with NestedViewTemplate.

Hi Bilal

Can you Tel med a little more about what was wrong. I have the same problem.

Jan,

Change your Application Settings and set debug=false. I am not sure what causes the Grid to crash in debug mode but that's what wasted my several hours.

Don't forget to give a smile if it helps.

Cheers
