In EditWinAttachments.aspx there is a variable that is null which should not be null. If you show some details about what you do in EditWinAttachments.aspx it might be easier to point down exactly on what the problem is.

I see that you are using a Grid View from Telerik, are you sure that the DataSource is not null when you try to DataBind() ?
