Touch-problems with RadScheduleView

[Manuel]

Hello,

i'm currently using the ScheduleView for showing appointments on a touchscreen. I changed the theme of the ScheduleView so i could open the EditAppointmentDialog with a single tap. The first problem is that the EditAppointmentDialog only shows when i click on a certain area of the appointment. It seems like the frame of the appointment where it reacts to the tap is slightly moved down. I attached a screen with the appointment - the black border illustrates where i need to tap to open the dialog.
This problem only occurs only on the touchscreen though, if i run the application on a normal screen and select the appointments with a mouse it shows no abnormal behavior.
When i try to select the rows of the calendar or press buttons the click is recognized at the right location, so the probelm only occurs when trying to open the EditAppointmentDialog. This makes me think it is a problem with the control and not an issue with drivers or the touchscreen.

I also defined a custom ViewDefinition for a work week, from Monday-Saturday, which leads to my second problem. When i try to pinch within this ViewDefinition i get an InvalidOperationException with the Message 'TimeRulerMonthViewGroupItem' TargetType does not match type of element 'TimeRulerGroupItem'. I found a similiar issue in this thread: http://www.telerik.com/community/forums/wpf/scheduleview/crash-while-pinch-to-zoom.aspx - but the workaround that was posted there didn't work for me.

The exception details:

System.InvalidOperationException was unhandled
  HResult=-2146233079
  Message='TimeRulerMonthViewGroupItem' TargetType does not match type of element 'TimeRulerGroupItem'.

Hello Manuel,

Thank you for contacting us.

You say that after the change of the behavior of the showing of the EditAppointmentDialog the clickable border of the Appointment has shifted, or this is the case by default?
In any case could you please open a support ticket and send us a sample project where this can be observed, as when I am testing, I am not able to reproduce the described behavior.
Also, I am sending you a short video of my attempt to reproduce the second issue you are describing - the thrown exception when pinching in the custom view.
Please, let us know with which assemblies you are testing and what is the model of your touch screen and the operating system you are running.

Looking forward to your reply.

Regards,
Konstantina

Hello Konstantina,

thank you for your fast response.

Regarding the first issue, it only occurs when binding the SpecialSlotsSource to an ObservableCollection of Slot. I tried to make my schedule read only like it is shown in the examples. So i bound the SpeacialSlotsSource to an ObservableCollection to which i added a Slot with IsReadOnly. After this i could reproduce the behavior i described above.

I was able to reproduce the pinch bug by using a ViewModel and binding the AppointmentsSource to an ObservableCollection. It has nothing to do with any custom ViewDefinitions as i thought before, it also works fine when setting the AppointmentsSource within the code behind - it only occurs if i use data binding for the appointments.

I'm running it on Windows 7 and the Dell 22 Touch Monitor - S2240T and i'm currently using v.2013.3.1016.45 of the RadControls.

Kind regards,
Manuel

Hello Manuel,

I tried to reproduce the described issues in our online demos - I used the Special and ReadOnly slots example for the second issue, and the First look and Configurator for the first, however, with no success.
Anyway, the demos use the latest version Q3 2013 SP 1 - could you please give a try with it and if you still experience the problems, please open a support ticket and send us a sample project, where these issues can be reproduces. I am using the same monitor and Win 7 OS.

Looking forward to your reply.
