Splitter

I have been unable to resolve this problem, even using asp:panels as suggested.

I have a RadSplitter (v2015.3), alignment is horizontal.

2 panes reside within it.

One at the Top for a RadMenu.

One beneath as a contentPane.

Menu items when clicked, do not show the LoadingPanel.

Thx

Neal

Hi Neal,

If you want the RadWindows to show a loading indicator, you should set their ShowContentDuringLoad property to false: http://demos.telerik.com/aspnet-ajax/window/examples/showcontentduringload/defaultcs.aspx.

Individual RadPane instances also offer the ShowContentDuringLoad property so if you change their ContentUrl (either via server code or via JS), they can show a loading indicator by themselves.

Otherwise, if the menu navigates the entire page to a new URL, showing a loading indicator is not possible with our controls, because the browser disposes the page and our controls with it.

Hello Neal,

Can you confirm the RadPane whose ContentUrl you set has its ShowContentDuringLoad property set to false?

I just tried the following and it works for me:

<script>

function setUrl() {

$find("<%=RadPane2.ClientID%>").set_contentUrl("some-page.aspx");

}

</script>

<telerik:RadSplitter ID="RadSplitter1" runat="server">

<telerik:RadPane ID="RadPane1" runat="server">

<asp:Button ID="Button1" Text="set new url" OnClientClick="setUrl(); return false;" runat="server" />

</telerik:RadPane>

<telerik:RadPane ID="RadPane2" runat="server" ShowContentDuringLoad="false">

<asp:Label ID="Label1" Text="some initial content" runat="server" />

</telerik:RadPane>

</telerik:RadSplitter>

In your case, RadPane2 corresponds to your RadPane2 if I understand correctly.

I also advise against setting a pane's dimensions to 100% because this would cause a conflict since it should not leave room for other adjacent panes.

If comparing your setup with this does not help you resolve the problem, I advise that you open a support ticket and send us a small runnable version of your page that showcases the problem so we can examine it.
