Activating Sliding Pane Programmatically Server-side

[Ben Thompson]

I have a pretty simple situation where I have the following arrangement:-
<telerik:RadSplitter ID="Radsplitter1" runat="server"......
    <telerik:RadPane ID="Radpane1" runat="server" .....
        <telerik:RadSlidingZone ID="Radslidingzone1" runat="server" ....
            <telerik:RadSlidingPane ID="rsp1" ...... 
            <telerik:RadSlidingPane ID="rsp2" ...... 
            <telerik:RadSlidingPane ID="rsp3" ...... 

All I want to do is to be able to programmatically, on the server side, make the contents on the "rsp2" to be selected and visible to the user. Is it possible or can it only be activated/selected by the user?

Hi Ben,

In order to expand sliding pane server-side you need to set the ExpandedPaneId property of its parent sliding zone to point to the ID of the required pane, e.g.:

<telerik:RadSplitter ID="RadSplitter1" runat="server">
    <telerik:RadPane ID="RadPane1" runat="server">
        <telerik:RadSlidingZone ID="RadSlidingZone1" runat="server">
            <telerik:RadSlidingPane ID="RadSlidingPane1" runat="server" Title="SlidingPane1">
                Pane1
            </telerik:RadSlidingPane>
            <telerik:RadSlidingPane ID="RadSlidingPane2" runat="server" Title="SlidingPane2">
                Pane2
            </telerik:RadSlidingPane>
            <telerik:RadSlidingPane ID="RadSlidingPane3" runat="server" Title="SlidingPane3">
                Pane3
            </telerik:RadSlidingPane>
        </telerik:RadSlidingZone>
    </telerik:RadPane>
    <telerik:RadPane ID="RadPane2" runat="server">
    </telerik:RadPane>
</telerik:RadSplitter>

<asp:Button ID="Button1" Text="Expand Pane2" runat="server" />

Code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    Button1.Click += new EventHandler(Button1_Click);
}

protected void Button1_Click(object sender, EventArgs e)
{
    RadSlidingZone1.ExpandedPaneId = RadSlidingPane2.ID;
}

I hope this helps.

Kind regards,
