I have a static grid with dynamically created columns. I followed the recommendation in www.telerik.com/help/aspnet/grid/grdprogrammaticcreation.html under the "Create Telerik RadGrid statically, but add its structure dynamically." section to do this.
So far, I have a working grid with several dynamically created bound columns as well as a GridButtonColumn (without Filtering and Sorting). This grid is currently using ajax and generating successfull asynchronous postbacks on Refresh/sorting/filtering events.
However, when I tried converting to a GridButtonColumnWithFilteringAndSorting, no asynchronous autopostback occurs even though I have the AutoPostBackOnFilter set to true.
Sys.WebForms.PageRequestManagerServerErrorException: Cannot create column with the specified type name: GridButtonColumnWithFilteringAndSorting.
I am not really sure what my problem is so any help on this matter would be greatly appreciated.
Thank you in advance,
