    I like to get the RadPane on the RadSplitter collapsed from codebehind preferably after post back. I saw few options using javascript but I want to do it on the codebehind so I can do it after every post back. Or I want the radpane to show collapsed after every page postback even with ExpandPanelId set. 

    Please gimme some solution.

    Hi Vijai,

    I have already answered your support ticket on the subject. For convenience I will paste my answer here as well:

    If I understand you correctly you need to have the sliding pane expanded only on initial load and collapsed on subsequent postbacks. To achieve this, you need to manually clear the ExpandedPaneId property of the parent sliding zone, e.g.:
    protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            RadSlidingZone1.ExpandedPaneId = "RadSlidingPane1";
            RadSlidingZone1.ExpandedPaneId = "";

    You need to manually clear the ExpandedPaneId because by design RadSplitter preserves the its state over postbacks.

    Best wishes,
