Thanks, Jenny -Why is it not possible to use the Enable Callback = false in Pop Up Edit Form mode? The cause of the problem is that grid gets its Post Data after the Page_Init event but before the Page_Load event. Data Bind method is called in the Page_Load event handler, it disturbs values returned from Post Data. We recommend binding the grid in the Page_Init event handler. - When the user opens 2 tabs for the same page, the session data is not specific for those tabs and state saved in the session variable can conflict between pages (removed on tab1 but still available on tab2). 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.
The appropriate solution is storing the Data Source in the Session. Load Post Data to the required controls explicitly via the Dev Express.
Please take a look at the Features - Data Binding online demo, illustrating this approach in action.
A friend asked me to help him out on this and frankly it has me completely stumped as well.
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? Please take a look at the Grid Editing - Validation online demo, illustrating the manual validation.

I have a Grid View control and use old style manual binding with a Data Source property and invoke the Data Bind() method.
If you don't use one of the Data Source controls, you are required to handle the Row Updating event.
