URL generation is dynamic, server-side, so how to open a window from code behind?

[DukeVideo]

As the title says, I need to open a RadWindow with a customised URL, which is generated server-side. How is this possible?

On the old RadWindow (pre-Promoetheous) I would create a Panel and inject JavaScript in it to call the Open() method client-side, but this doesn't seem to work anymore.

At the moment, I have:

	<asp:Panel ID="pnlJavascriptInjector" runat="server" />
	<telerik:RadWindowManager ID="radWindowManager" runat="server" Skin="Vista">
	<Windows>
	<telerik:radwindow runat="server" ID="radWindowReport"
	VisibleOnPageLoad = "false"
	NavigateUrl = "Report.aspx"
	Title = "Import Media Codes"
	Height="80%"
	Width ="80%"
	Behaviors="Reload,Resize,Maximize,Minimize,Close,Move,Pin"  Modal="false"
	>
	</telerik:radwindow>
	</Windows>
	</telerik:RadWindowManager>

(notice my attemp to have JavaScript injection going on).

Note that this is within an AJAX environment. I do have an AjaxManager:

	<telerik:RadAjaxManager ID="radAjaxManager" runat="server">
	<AjaxSettings>
	<telerik:AjaxSetting AjaxControlID="radFolderTreeView" EventName="NodeClick">
	<UpdatedControls>
	<telerik:AjaxUpdatedControl ControlID="h1ReportName" LoadingPanelID="" />
	<telerik:AjaxUpdatedControl ControlID="pReportDescription" LoadingPanelID="radAjaxLoadingPanel" />
	<telerik:AjaxUpdatedControl ControlID="pnlReportParameters" LoadingPanelID="" />
	<telerik:AjaxUpdatedControl ControlID="pnlReportButtons" LoadingPanelID="" />
	<telerik:AjaxUpdatedControl ControlID="pnlJavaScriptInjector" LoadingPanelID="" />
	<telerik:AjaxUpdatedControl ControlID="radWindowManager" LoadingPanelID="" />
	</UpdatedControls>
	</telerik:AjaxSetting>
	</AjaxSettings>
	</telerik:RadAjaxManager>
	<telerik:RadAjaxLoadingPanel ID="radAjaxLoadingPanel" runat="server" Height="75px"
	Width="75px">
	<img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'
	style="border: 0px;" />
	</telerik:RadAjaxLoadingPanel>

My code-behind is:

	/*
	pnlJavaScriptInjector.Controls.Clear();0
	StringBuilder sb = new StringBuilder();
	sb.Append("\n");
	sb.Append("<script type=\"text/javascript\">\n");
	sb.Append("var oWnd = $find(\"" + radWindowReport.ClientID + "\");\n");
	sb.Append("oWnd.setUrl('" + url + "');\n");
	sb.Append("oWnd.show(); \n");
	sb.Append("</script>\n");
	sb.Append("\n");
	pnlJavaScriptInjector.Controls.Add(new LiteralControl(sb.ToString()));
	*/
	RadWindow radWindow = radWindowManager.Windows[0];
	radWindow.NavigateUrl = url;
	radWindow.OpenerElementID = button.ClientID;

You'll notice I've tried all sorts of ways of doing this!

Any help appreciated.

Hello DukeVideo,

You can show the RadWindow from code-behind by setting its VisibleOnPageLoad property to true in the button's handler as shown below:

RadWindow radWindow = radWindowManager.Windows[0];
radWindow.NavigateUrl = url;
radWindow.OpenerElementID = button.ClientID;
radWindow.VisibleOnPageLoad = true;
