Scroll appointment into view

[Oscar Wahlen]

How can I scroll appointments into view? I tried ScheduleView.ScrollTimeRuler as suggested, but I could not find the method. Was this method removed? I am using the latest internal build (2011.1.0427).

Hi Oscar,

The method is not visible in the IntelliSense because it might be changed in the future. However, you can still use it. It takes two parameters: ScrollTimeRuler(TimeSpan, bool) - The first parameter specifies the time which should be scrolled to, the second specifies whether to scroll that time to the top/left, or not.

Hope this information helps.

I have had no success with either ScrollTimeRuler or ScrollIntoView.  Can you post a sample project that illustrates their use?  I'm particularly interested in ScrollIntoView.

Hi Oscar,

You can check out the ScrollIntoView() method very easy in Reflector. There you will find all the necessary information for all the overloads. Please find the screenshot for reference.

Hope this will help. Let is know if you still experience difficulties by providing more information about your scenario.

Still having trouble with ScrollIntoView.  Here's a code snippet.  Is anything obviously wrong?

            Dim apt As Appointment = DirectCast(viewModel.MyApptCollection(0), Appointment)
            ' Neither of these works...
            RadScheduleView1.ScrollIntoView(apt)
            RadScheduleView1.Dispatcher.BeginInvoke( _
                Sub() RadScheduleView1.ScrollIntoView(apt) _
                )

Hi Steve,

This is how I use the ScheduleView.ScrollIntoView method.

Scroll with date grouping and align to left (no resource grouping):

this.MyScheduleView.ScrollIntoView(myApp, true);

Scroll with date and resource grouping and align to left:

this.MyScheduleView.ScrollIntoView(myApp.Start, true, myApp.Resources.Where(x => x.ResourceType == typeof(Employee).Name).Select(x => x).ToList());

I did however notice the ScheduleView was not scrolling in both directions with either Day or Week view activated. I had to manually adjust the ScheduleView.HorizontalOffset/VerticalOffset.

I added the Boolean to my call but nothing happens.  The calendar still starts out on the current date.

 

Is there a timing issue here?  I am doing this in the MainPage constructor, right after the ViewModel object is created.  It’s likely that the visual tree has not yet been fully constructed, so perhaps that is an issue.  I also tried wrapping ScrollIntoView() in a Dispatcher.BeginInvoke, but there was no difference.

Hello Steve,

Please set also CurrentDate property of the RadScheduleView, so that the appointment to be loaded in the view before calling ScrollIntoView() method.

Hope this helps.

Hi,

I am facing a similar problem, I need to set the vertical scrollbar to 8:00AM rather than 12:00AM, I have written the below piece of code, but it doesn't seem to work, any suggestions. it would be nice if you could send a sample code.

  private void ScheduleView_VisibleRangeChanged(object sender, System.EventArgs e)
        {
            if (ScheduleView != null)
            {
		timeSpan = TimeSpan.FromTicks(ScheduleView.CurrentDate.AddHours(8).Ticks); //current day default to
		12:00AM so added 8 hours.

                ScheduleView.ScrollTimeRuler(timeSpan, true);
             
		//tried this too.
		//ScheduleView.ScrollIntoView((ScheduleView.AppointmentsSource as ObservableCollection<Event>)[0], true);
            }
        }

your quick response would be appreciated.

Thanks,
Jayadev

Got it!

I had to write the piece of code in ScheduleView_LayoutUpdated event handler, and it works.

  private bool _shouldUpdate = true;
        private void ScheduleView_LayoutUpdated(object sender, EventArgs e)
        {
            if (ScheduleView != null && ScheduleView.ActiveViewDefinition is DayViewDefinition && _shouldUpdate)
            {
                _shouldUpdate = false;
                TimeSpan timeSpan = TimeSpan.FromTicks(DateTime.MinValue.AddHours(8).Ticks);
                ScheduleView.ScrollTimeRuler(timeSpan, true);
            }
        }

A faster version that does not use a global variable:

private void ScheduleView_LayoutUpdated(object sender, EventArgs e)
{
    if (ScheduleView != null && ScheduleView.ActiveViewDefinition is DayViewDefinition)
    {
        ScheduleView.LayoutUpdated -= new EventHandler(ScheduleView_LayoutUpdated);
        TimeSpan timeSpan = TimeSpan.FromTicks(DateTime.MinValue.AddHours(8).Ticks);
        ScheduleView.ScrollTimeRuler(timeSpan, true);
    }
}

I found that using ScrollTimeRuler can not sustain. If you switch to WeekViewDefinition and switch back. The time scroll setting disappeared. Is there any way the scroll setting can be hold!

Thanks
