Hi..I'm using EntityDataSource and QueryExtender to display records on my page in gridview. The problem is I'm getting error of
'col1' is not a member of type 'System.Data.Common.DbDataRecord' everytime my page is AutoPostBack. This error can be solved by removing Select attribute in my EntityDataSource, but I cannot remove it as I need to use GroupBy for my records.
Is anybody can help me pls? Thx..
