I have Radwindow which Pops up by clicking ImageButton on RadGrid and Radwindow is not working whenever i set its Property Visible = true. Though its working by setting visibleonpageload=true. but it pops up every time page is loaded.
<telerik:RadWindow ID="radtooltipshowbom" AutoSize="true" KeepInScreenBounds="true" AutoSizeBehaviors="Default" ContentScrolling="Y" RenderInPageRoot="false" runat="server" Modal="true" HideEvent="ManualClose" Style="z-index: 6990" Position="TopCenter" BackColor="White" Width="1510px" Height="670px">
