RadSlider not visible on RadWindow

[Marco Miccini]

I've an aspx page with inside a <RadWindow ...><ContentTemplate><telerik:RadSlider id="rl" ...></ContenTemplate></RadWindow> .
The RadWindow is set with VisibleOnPageLoad="true".
In the RadWindow I can see all the controls except the RadSliders that remains not visible: why?
I've tried to call a javascript function on the OnClientShow of the RadWindow to repaint the sliders as suggested in an anwser in these forums as follows:

function

 

OnClientShow(sender, eventArgs) {
var wnd = $find("<%= rl.ClientID %>");

 

slider.repaint();}

Unfortunately it does not compile since the "rl" control is inside a ContentTemplate and I do not know how to access this element from javscript.
Any help?

Hi Marco Miccini,
You can use the following approach to get a reference to the slider control:

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

    <telerik:RadWindow ID="RadWindow1" runat="server" VisibleOnPageLoad="true" OnClientShow="OnClientShow">
        <ContentTemplate>
            <telerik:RadSlider ID="RadSlider1" runat="server"></telerik:RadSlider>
        </ContentTemplate>
    </telerik:RadWindow>

    <script type="text/javascript">
    function OnClientShow(sender, args)
    {
        $find('<%= RadWindow1.ContentContainer.FindControl("RadSlider1").ClientID %>').repaint();
    }
    </script>
</form>

Dear Tsvetie,
thanks a lot for your help, your support at Telerik is always fantastic!
Now the javascript works and, more important, the comboboxes in the RadWindows are finally visible.
