Major drawing issue


We use a custom AppointementTemplate that it is not hyper fancy. We use the Syncfusion technique to have a custom AppointementTemplate.

In the provided video, you'll see that when moving month using the previous and next buttons, the drawing is good. However, when using the scroll wheel, most of the items are losing their background and image.

I have also noticed that the issue arises when the ItemsSources receives a CollectionChanged event.

Thank you

I was able to reproduce the issue with the SampleBrowser solution from Syncfusion. I modifed it a bit the Patient Monitor.

I pinpointed the problem (but I don't have the solution).

It appears that there is a binding problem with the AppointmentTemplate. I added a converter CalendarDisplayTypeToBGBrushConverter and uses this converter:

Fill="{Binding Title, Converter={StaticResource CalendarDisplayTypeToBGBrushConverter}}"

You'll see the issue right away after launching the PatientMonitor.

If instead you change the previous line to:


The problem dissapears.

Good luck!

FYI, because your file upload has a 30MB limit, I was not able to send the full sample project of Syncfusion. I deleted the PDF books from the Zip, but I forgot to delete the file references in the project. I'm pretty sure you know where the books are!
