Thank you for contacting us.
I am afraid that we're not aware of a way to synchronize the scrolling of two ScheduleView instances. RadScheduleView provides methods only to scroll to certain appointment or slot and to a certain time - ScrollIntoView, ScrollTimeRuler.

1) Initialize both ScheduleViews to the same date/time:
2) Keep the two in sync by using the LayoutUpdated event of one of the views (in my case, I have hidden the horizontal scrollbar entirely from the top view, so the bottom view should keep the top view in sync when scrolling):
This was my case, works well, thank you!
I have a similar requirement - 2 timelines on the one page. I want to have one horizontal scroll bar to control the scrolling and zooming of both timelines in sync with each other. I also want the time ruler portion of the bottom timeline to disappear so it appears that there are two sets of data being controlled by one horizontal scroll bar. Also the scroll bar of the top timeline is be hidden.
Could you please, let us know if you questions is related to RadTimeLine or is about RadScheduleView? Using that information we will try to provide you with an appropriate solution in order to achieve the desired behavior and functionality.
We are looking forward to hearing from you.

Hi Nasko. I got a good reply from a support request #1088568. The issue was with synchronising multiple timelines. The solution was to bind the start, end, visible and actual visible periods from one timeline to the others - this kept the timelines in sync as the window was resized or when the scroll bar zoomed or panned over the data. This, coupled with hiding some of the template components resulted in a solution which is almost working.
The response sent to me is as follows:
There is not built-in
mechanism that will allow you to easily align the timeline controls. However,
you should be able to do it with some custom code. For example, you can sync
the ranges of the timeline using the PeriodStart, PeriodEnd,
VisiblePeriodStart, VisiblePeriodEnd and ActualVisibleRange properties.
To hide the horizontal scrollbar you can set the ScrollMode property to None. Or you can use the SliderStyle property if you prefer.
To hide the periods and the group periods at the top of the control you will need to modify some styles. You can extract the RadTimeline ControlTemplate. Then find the TimelineGroupPeriodContainer and TimelinePeriodContainer controls and set their Visibility to Collapsed. You can also hide the gray border that separates the periods and the groups periods. To do this you can set the Visibility of one of the Border element from timeline template. The border is a child of the first Grid which is a child of the TimelineAnnotationsPanel. The attached image demonstrates where the elements are positioned in the hierarchy.
Additionally, I attached
a small example demonstrating how you can customize the timeline control.
Instead of extracting the template, the example uses an attached property and
gets the timeline containers in code. Note that the approach demonstrated in
the project is merely a suggestion which is not well tested and I cannot
guarantee that it will work properly in all expected scenarios. This is why I
recommend you to use it only as a reference for implement your own solution.
I am glad to here that you were able to achieve the desired and thank you for sharing with the community the suggested approach.
If you have any additional questions or concerns please, do not hesitate to contact us.
