RadToolTipManager Error when double clicking event

[Alex Occhipinti]

I have a RadScheduler and a RadToolTipManager that I use to show a custom hover over the events.  Following an example I used this code to add the tooltips to the events:

    protected void rsCalendar_AppointmentCreated(object sender, Telerik.Web.UI.AppointmentCreatedEventArgs e)
    {
        if ((e.Appointment.Visible) && (!IsAppointmentRegisteredForTooltip(e.Appointment)))
        {
            string strId;
            if (e.Appointment.RecurrenceState != Telerik.Web.UI.RecurrenceState.Occurrence)
                strId = e.Appointment.ID.ToString();
            else
                strId = e.Appointment.RecurrenceParentID.ToString();

            foreach (string strDomElementId in e.Appointment.DomElements)
                RadToolTipManager1.TargetControls.Add(strDomElementId, strId, true);
        }
    }
    private bool IsAppointmentRegisteredForTooltip(Telerik.Web.UI.Appointment Appt)
    {
        foreach (Telerik.Web.UI.ToolTipTargetControl ttControl in RadToolTipManager1.TargetControls)
            if (Appt.DomElements.Contains(ttControl.TargetControlID))
                return true;
        return false;
    }

Here is the .aspx side

    <telerik:RadToolTipManager ID="RadToolTipManager1" runat="server" OnAjaxUpdate="RadToolTipManager1_AjaxUpdate"
        Width="300px" Height="80px" Text="Loading..." OnClientBeforeShow="clientBeforeShow"
        HideEvent="LeaveToolTip" Animation="None">
    </telerik:RadToolTipManager>

  The OnClientBeforeShow simply centers the tooltip.

  If I let the tooltip come up and then double click on an event it open the event and shows no error.  Likewise, if I double click quickly after I move the mouse onto the event I receive no error.  However, if I hesitate and do something in between the following error is shown:

RadToolTipManager response error:
 Exception=Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0

  The double click is processed and the event's details are shown, but now under the error pop-up.  This only appears to be happening in Firefox and Chrome.

Thanks!

Hello Alex,

Can you clarify whether you need to modify the current functionality from the online demo and how? The demo works fine under all supported browsers so I wonder if you can use it as it is.


Kind regards,

  Sorry for taking so long to reply.  The example shown is what I had been following.  It looks like it was updated slightly since I last used it, so I updated a sample project on my own following the same method.  Attached is the sample project that exhibits the pop-up error behavior indicated previously under Firefox.  This appears to have something to do with the Javascript of the RadTooltip, but I can't trace it down to anything specifically.  Any help is great appreciated.

Scheduler.aspx

<script type="text/javascript">
    function hideActiveToolTip() {
        var tooltip = Telerik.Web.UI.RadToolTip.getCurrent();
        if (tooltip) {
            tooltip.hide();
        }
    }

    Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginRequestHandler);
    function beginRequestHandler(sender, args) {
        var prm = Sys.WebForms.PageRequestManager.getInstance();
        if (args.get_postBackElement().id.indexOf('RadScheduler1') != -1) {
            hideActiveToolTip();
        }
    }

    function clientBeforeShow(sender, eventArgs) {
        w = $telerik.$(window).width() / 2;
        h = $telerik.$(window).height() / 2;

        if ((sender._mouseX > w) && (sender._mouseY > h)) {
            sender.set_position(Telerik.Web.UI.ToolTipPosition.TopLeft);
            return;
        }
        if ((sender._mouseX < w) && (sender._mouseY > h)) {
            sender.set_position(Telerik.Web.UI.ToolTipPosition.TopRight);
            return;
        }
        if ((sender._mouseX > w) && (sender._mouseY < h)) {
            sender.set_position(Telerik.Web.UI.ToolTipPosition.BottomLeft);
            return;

Hello Alex,

It looks like you handle AjaxUpdate differently. Please, see the code we use in the demo:

protected void RadToolTipManager1_AjaxUpdate(object sender, ToolTipUpdateEventArgs e)
        {
            int aptId;
            Appointment apt;
            if (!int.TryParse(e.Value, out aptId))//The appoitnment is occurrence and FindByID expects a string
                apt = RadScheduler1.Appointments.FindByID(e.Value);
            else //The appointment is not occurrence and FindByID expects an int
                apt = RadScheduler1.Appointments.FindByID(aptId);

            AppointmentToolTip toolTip = (AppointmentToolTip)LoadControl("AppointmentToolTip.ascx");
            toolTip.TargetAppointment = apt;
            e.UpdatePanel.ContentTemplateContainer.Controls.Add(toolTip);
        }

AppointmentToolTip.ascx is the user control that displays the tooltip content and you need to register it in your aspx page like this:

<%@ Reference Control="AppointmentToolTip.ascx" %>

I implemented the indicated changes and receive the same results.  That is, the error message is still showing.

Hello Alex,

Can you send us a simple working demo of the issue via a support ticket? We will test it locally and do our best to provide you with a solution.

Peter, I do have a working example that demonstrates the issue, but I do not believe that I can open a support ticket since I do not have an active subscription.  Could this be a bug in the version of controls that I am using?  I posted the exact code above that I am using in my demo.  I am using this with version 2009.3.1208.

[Peter]

Hi Alex,

Yes, it is quite possible that this is a version specific problem. I have noticed that you have indicated that you use version 2010.1 519 in this thread's details. Can you try upgrading to at least this version and let us know how it goes?


Best wishes,
Peter

[Alex Occhipinti]

Is there someway to do that without having to fork out $800?  Or were you suggesting that the only fix for this would be to buy an upgrade to the latest version?

[Peter]

I suggest you try with the trial version first to be sure that the problem will be solved. If yes, then let me know and I will negotiate a discount for your license renewal.

Peter, I just tried with version 2010.2.826.35 and received the same failure.

[Peter]

Okay, then this means that the error is probably caused by something in the implementation and not a bug with the controls. I wonder if you can open  a support ticket and send us a simple working demo which we can test locally. I am asking for this because, we cannot experience the problem with our local tests.


All the best,
Peter
