Hi Venkateswararao,

Please add the main grid from which the two other Grids are populated as initiator for ajax request in the RadAjaxManager settings and both RadGrids which are populating depending on the first one selection to be updated controls. Also please note that the window which popups also should be added as updated control. If this doesn;t work for you, please try to wrap the three RadGrid controls and the radWindow control into single RadAjaxPanel and verify of this works for you.
