Visual Studio allows developers to quickly put together a Web Forms page simply using drag and drop options from the Visual Studio editor.
Binding form controls is mostly a simple matter of attaching a Data Source and setting your controls to reference the correct field in the Data Source.
Binding a Grid View control can sometimes get tricky when using the Visual Studio editor, especially when working with Drop Down List controls within the grid.
Today I was working on getting a row of the Grid View control to save the contents of a Drop Down List, and needed to add some custom code to set values passed to the Sql Data Source control on the update event.
According to your project, Edit Form template controls are not bound to Data Source. (2) How do you add validation to this pop Up Edit Form approach?

Viewstate is page-specific and only lives within lifecycle of let's still use session data as you specify, I'll try to solve that later.== I have 2 questions using your example:1) The e.
