i have a RadGrid in a usercontrol.
i have an aspx page that contains the usercontrol and a RadFilter.
how can i assign the FilterContainerID of the RadFilter to the RadGrid?
i already tried to directly giving it the ID as such:
and i have also tried to assign filterContainerID in code behind as such:
rfCustomFilter.FilterContainerID = "RadGrid1";
both did not work, and i get an error when Adding an expression:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
