I have a grid which use popup edit mode and set the popup at the center of the screen(http://www.telerik.com/help/aspnet-ajax/grid-center-popup-edit-form.html). Inside the grid, I also included a cascading dropdown in the edit form with ajax postback.
The problem that I am facing now is as below
1) I open edit form and the popup edit form open at the center of the screen as expected.
2) I manually align it to the right of the screen.
3) Then I selected cascading drop down list and the edit popup screen went back to center again.
How can prevent from going back to center once I align to other area?
Thanks

The pop up centers again in the middle of the screen most likely because the dropdown cause post postback and fires again the PopUpShowing event. So you need to prevent this from executing the second time. You can either disable the postback for the dropdown if is on or set some flag in one of the client events for the dropdown (in case you are using RadComboBox) that you can check when you go again through the PopUpShowing event to prevent the code from executing. Another event that you might find useful is the OnCommand client-side event which indicates that edit command has fired so this might be another suitable place for setting a boolean variable that will allow the pop up to be shown only initially. There are many client-side events that you can choose from, you just need to find the one appropriate in your case.

Thanks for your help in the first place. Can you give me some sample code to achieve option no.2 using other client-side event?
Thanks for your help
You can go trough the following links (containing code samples) which show how you can specify the position of the PopUp Edit form in RadGrid:
Customize RadGrid PopUp edit form position with an extender
Position PopUp edit form in RadGrid (this one shows how you can center the pop up, but the approach is the same - you can specify any coordinates for style.top and style.left that you wish).
