Hi,

Does anybody has an example on how to convert from the asp.net Toolkit ModalPopupExtender to the RadWindow control?
Basically I have this code:

<asp:Button runat="server" ID="hiddenTargetControlForModalPopup" style="display:none"/>

<ajaxToolkit:ModalPopupExtender ID="ModalPopupExtenderAddEditSample" runat="server"                
				TargetControlID="hiddenTargetControlForModalPopup"                
				PopupControlID="PanelSamples"
				BackgroundCssClass="modalBackground"                 
				DropShadow="true"                                
				>
				</ajaxToolkit:ModalPopupExtender>       
		<!-- modal popup -->
		<asp:Panel ID="PanelSamples" runat="server" Style="displaynone" CssClass="modalPopup"> 
			<asp:UpdatePanel ID="UpdatePanel1" runat="server">                
				<ContentTemplate>
				<!-- a bunch of controls and HTML -->
				</ContentTemplate>            
			</asp:UpdatePanel>
		</asp:Panel>
Is there an easy way to covert this code to a RadWindow? Thanks!

Hello,

Making RadWindow as modal is nearly simple by setting the "Modal" property to "True".

<telerik:RadWindow ID="RadWindow 1" runat="server"  Modal="true">

Also take a look into this for more.

Thanks,
Princy.

Princy:

Thank you for your prompt answer. the problem I'm having now is that my popup requires to be opened after a click event on a linkbutton control. With my current code, in order to show the popup, all I had to do was to call this:

this.ModalPopupExtenderAddEditSample.Show();

RadWindow does not seem to have any equivalent method. Is the only way to achieve that by hooking to the clientScript the javascript code?

Hello Chris,

The RadWindow is a client-side object and thus must be shown via JavaScript. You can use the LinkButton's OnCilentClick event to open the Radwindow and cancel the postback (if it is only an AJAX request that will not dispose the RadWindow you may not cancel it), for example:
<asp:LinkButton ID="Linkbutton1" Text="some text" OnClientClick="JsFunctionToOpenTheRadWindow(); return false;"  runat="server" />

Please also examine this help article on the ways to open a RadWindow: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html. If you explicitly need to do this from the server please examine this thread: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx.

I believe examining the Client-side API of the RadWindow will also be helpful: http://www.telerik.com/help/aspnet-ajax/window-programming-radwindow-methods.html.

Kind regards,
