I have a radgrid on my ascx, and it has autogenerated columns.
I want to add a "GridClientSelectColumn" to RadGrid in code behind. I can add it using this code on the Page_Init method:
It is working, but if the page is postback, i am giving an error like this:
"Cannot create column with the specified type name: GridClientSelectColumn"
How can I solve this problem?
(My RadGrid version is 126.96.36.199)
