I am building a radgrid programmatically. Can anyone tell  me how to find out if a particular DataKeyName exists in the grid - something like e.Item.OwnerTableView.DataKeyNames.Contains("OBJECTID"). Since this is a generic grid, I might not know if a datakey exists. When I try to use GetDataKeyValue I get a null reference exception because a datakey might not exist.

Hi Terry,

If set, the DataKeyNames can be accessed in the RadGrid1.MasterTableView.DataKeyNames property (server-side) which returns an array of strings ( string[] ). Then you can check to see if it contains a particular value as suggested in the following StackOverFlow article: https://stackoverflow.com/a/2912507

I hope this will be helpful!

Kind regards,
