    cannot create an instance of

    telerik.wincontrols.ui.gridviewdatacolumn because it is an abstract class

    Hi Nazeer,

    I have tested this with the latest version but the dialog looks different on my side (see attached image). Which version are you using?

    I am looking forward to your reply.

    Telerik by Progress
