    I am currently using the RadToolTipManager successfully to add a usercontrol dynamically, but it loses the "Text" setting after the control is added.  I would like to add the text property back using "OnClientHide" event, but when I add the javascript function and use the set_text method, the page reloads after the text is set.

    What is the best way to get this done?  I also tried to set the "OnClientHide" property to a "Protected Sub" on the VB codebehind file, but I get a Javascript error that the method is undefined.  What would be the proper parameters on the codebehind sub that need to be delcared?

    Thank you,

    Hello Ed,

    OnClientHide is a client-side event handler by JavaScript, not by server code.

    What I can suggest is using the TItle of the tooltips to display your initial/loading text. Here is a small example:
    <div id="target" style="width: 100px; height: 100px; background: yellow;">
    <telerik:RadToolTipManager ID="RadToolTipManager1" runat="server" Title="Please wait..."
                               OnClientBeforeShow="storeOriginalTitle" OnClientHide="resetTitle" OnClientResponseEnd="removeTitle" OnAjaxUpdate="OnAjaxUpdate"
                               Width="200px" Height="120px" RelativeTo="Element" Position="BottomRight">
            <telerik:ToolTipTargetControl IsClientID="true" TargetControlID="target" />
    and with the following scripts to handle the title:
    function storeOriginalTitle(sender, args) {
        if (!sender.__oldTitle)
            sender.__oldTitle = sender.get_title();
    function resetTitle(sender, args) {
        if (sender.__oldTitle) {
    function removeTitle(sender, args) {
        var activeTooltip = Telerik.Web.UI.RadToolTip.getCurrent();
        if (activeTooltip) {
