Appointments.FindByID not work with RadToolTipManager OnAjaxUpdate

[Vikram]

I'm trying to show appointments in TimeLineView grouped by resources. For each appointment in RadScheduler, I want to display dynamic tooltip. For that I had used RadToolTipManager and OnAjaxUpdate.

Code Snippet - 

protected void RadToolTipManager1_AjaxUpdate(object sender, ToolTipUpdateEventArgs e)
    {
        // THIS WORKS SUCCESSFULLY
        Appointment appointment = null;
        foreach (var apt in EventScheduler.Appointments.Where(apt => apt.ID.ToString().Equals(e.Value)))
        {
            appointment = apt;
            break;
        }

        // CODE COMMENTED BELOW NOT WORKS. WHY?
        //int aptId;
        //var appointment = int.TryParse(e.Value, out aptId) ? EventScheduler.Appointments.FindByID(aptId) : EventScheduler.Appointments.FindByID(e.Value);

        if (appointment == null) return;

        var toolTip = (AppointmentToolTip)LoadControl("UserControl/AppointmentToolTip.ascx");
        toolTip.TargetAppointment = appointment;
        e.UpdatePanel.ContentTemplateContainer.Controls.Add(toolTip);
    }

I am seeking answer to why part in code comment.  If it work one way, then it must work another way. Did anyone else noticed this bug?

I believe that the commented part is more optimized and fast in comparison to method I had implemented. So can Telerik team confirm that code I'm using would be equivalent fast?

Hello Vikram,

Having the information that you provided it should be possible to find any specific appointment with a specified id with the code below:

//where the RadScheduler1 id the ID of the RadScheduler control
  RadScheduler1.Appointments.FindByID("");

However, if the approach that you currently apply works as expected you can also use it as an alternative to get the desired behavior.

Hello Kate,

I agree with you. But you didn't answered why part in code.

Hi Vikram,

I have been testing the scenario that you described and the code that you provided with this demo and I was not able to get the issue that you get. I tried both your code and the code from the demo and I was able to find the appointment. Let me know if there are any particular steps that I need to follow to get the behavior that you currently experience.
