I have created one table with the name Group and I want to bind that table using Telerik ORM but I am getting this exception.
Exception :
An exception occured during the execution of '
Extent<FFDataLibrary.FFDAL.FF_Group>'.
Code :
Protected Sub BindGrid()
Dim query = obj_DBContext.GetAll(Of FF_Group)()
rgGroup.DataSource = query.ToList
rgGroup.DataBind()
End Sub
