I'm using entity framework and binding a GridView to a entity collection.
I've got an entity Complaint. It has a collection of Resolutions. Each resolution has a collection of Actions. So my grid binds to Complaint.Resolutions. And I've got a HierarchyChildTemplate defined which binds to the Actions collection.
My ActionGrid has CanUserDeleteRows = True and CanUserInsertRows = True. I've also set ShowInsertRow = True.
deleting rows keeps triggering an error from EF about the required relationship being null. How do I capture this? I think it has something to do with how the row gets added. Right now I'm binding to the Deleted event and then looping through each item and telling the context to delete it. But the problem is that by then it's already been removed from the collection, so when I try to save, I still get the foreign key is null error.
Trying to capture the deleting event isn't working. When is this event raised? I've tried binding to it, but my command isn't being hit when I press the Delete key for a row. The row is just removed from the collection.

Is it possible to use mouse-scrolling to zoom the current view of the ScheduleView.
E.g. in day view the hours from 00:00 to 10:00 fit on one screen, scrolling the mousewheel down zooms out so that the whole day fits into one screen, while scrolling the mouse-wheel up zooms in.
And is it possible to use panning to scroll in the views?
I do not need to drag&drop appointments, so I was wondering if it would work to use the mouse to navigate/scroll in the view.
These two things combined would be very useful in timeline view. The user could zoom in and out using the mouse-wheel and navigate by panning.
Any suggestions how to do this?

I am using RadCarouselPanel control. Instead of images as my items, I am using Labels to show some text. When I click on an item 9Label), it doesn't move to the center and show as selected. How does I make that item selected?

Hi,

Because now double click works on everything, so if someone scroll the grid and double click on the row the event is fired, same when user double click on header column etc. I need to fire double click only on row. Also how can i make double click work only on left button? i checked in MouseButtonEventArgs e, i can see if it was left but i see only last click so i dont know if the first click was with right button or not.

Hi Telerik,
My ScheduleView binds AppointmentsSouce to a VM like
Thanks.
Cheau
My ScheduleView binds AppointmentsSouce to a VM like
public ObservableCollection<Appointment> Appointments { get { return _appointments; } set { _appointments = value; } }When creating an appointment by dragging item from other control like ListView, the binding won't fire in the VM, however when I checked the appointments collection in runtime, it was added correctly. My question is how can I track this event (not in code behind) in VM when an appointment item is added to ScheduleView?
Thanks.
