Crash while pinch to zoom

[Andreas]

Hello,
i am just playing around with the ScheduleView and i found an error.

If you are in the WeekViewDefinition and change to MonthViewDefinition using pinch to zoom i get the following exception:

System.InvalidOperationException wurde nicht behandelt.
  Message="TargetType 'TimeRulerMonthViewGroupItem'" entspricht nicht dem Typ des Elements "TimeRulerGroupItem".

Hello Andreas,

Following the explanations and the code snippet in your forum post we created a sample, but we didn't manage to reproduce the issue. We tested it under version 2013.2.724.

Sorry for answering late.

What i do is:

1. Start the Application 
2. Use pinch to zoom inside WeekViewDefinition zooming out.
3. Error

Here is a video showing the error. 

http://l4nk4b3l.de/error/

I am using de "Microsoft Surface 2.0 SDK Tool" to simulate touch on my Windows 7 machine.

Hello Andreas,

You may find a video attached showing our approach. We still do not manage to reproduce the crash. Please, take a look at it in case we are missing something important.

 The code in our sample is the same as the one you've sent us in the thread and we are using the same Microsoft Input Simulator for the test.

Hey Alek,

I can't see any differnce to yours but i am still able to reproduce the crash every time...


I uploaded the Solution http://l4nk4b3l.de/error/ScheduleViewError.zip here...

Hello Andreas,

Thanks to your simple project we were able to reproduce the exception. Therefore we have logged it here in our Public Issue Tracking System, where you can track its progress.
Also your points have been updated for the report.

Hello Andreas,

We have researched the issue further and it seems like it depends on when the DataContext is initialized. Therefore meanwhile this can be used as a workaround:

public MainWindow()
        {
            this.DataContext = this;

            InitializeComponent();

            this.Items = new ObservableCollection<Appointment>();

        }

Hi,
i'm glad to hear that you were able to reproduce the error.

Thanks for the workaround i'll try it out later!

Regards,
Andreas
