My RAD Grid has five columns and I am binding it to a DataSource.
In the last column i have an Template column which has 2 ImageButtons one is to Add a new row and the other is Delete ImageButton to delete row.
I have some mandatory Fields in Grid (ie. 2 of my columns in the Grid should always contain value it should not be empty).
Aftter performing my validation i displaying the validation message in RAD Window or RADGrid.ResponseScript based on the Event or method. My problem is whenever i get the validation message i am losing all my values in the Grid Column but i need to retain the value in the GridColumn if the validation fails,so that the user can just fill in the remaning columns and submit the page to Add the row.

I think this problem is because of the postback happening after the validation message windows button is clicked. 
Is there any property to resolve this or do we have any backdoor process to solve this issue.
I need your help on this, so please let me know the workaround for this issue?
Let me know if you can understand the scenario.
I am using RAD Window and RADGrid.ResponseSCript to display the validation message depending on the Event and place.

Hello Bose,

Based on the information supplied, it is hard to pinpoint the cause of the issue, or suggest a solution for that matter. To further investigate the problem, it would be best if you open a formal support ticket, and send us a small project, demonstrating the issue.
We will review it locally, and advise you further.
