Random crashes

Using an Object-Relational hierarchy with two levels, I keep getting random crashes in the grid related to index out of bound or removing an item that is not in a collection when calling BindingList<T>.ResetItem. I have already opened a support ticket, but Telerik Support could not recreate the problem, hence no real help was provided.
It is hard to recreate the problem, but I would think with the detailed stack trace of the crashes, it should help point out where in the code it happens and add appropriate error handling.

Below is the stack trace of one of many crashes I have been getting, please let me know if you have seen similar problem before, or have any hints to get around this issue.

System.ArgumentException: Cannot remove the specified item because it was not found in the specified Collection.

at System.Collections.CollectionBase.System.Collections.IList.Remove(Object value)

at Telerik.WinControls.RadElementCollection.Remove(RadElement value)

at Telerik.WinControls.UI.GroupPanelElement.UpdateView()

at Telerik.WinControls.UI.GroupPanelElement.ProcessEvent(GridViewEvent eventData)

at Telerik.WinControls.UI.GridViewEventProcessEntity.ProcessCollection(GridViewEvent gridEvent, PriorityWeakReferenceList list, GridEventProcessMode processMode)

at Telerik.WinControls.UI.GridViewEventProcessEntity.ProcessEvent(GridViewEvent gridEvent)

at Telerik.WinControls.UI.GridViewSynchronizationService.NotifyListeners(GridViewEvent gridEvent)

at Telerik.WinControls.UI.GridViewSynchronizationService.OnPostCallback(Object state)

Thanks,
Andy

Customer Recurrence Dialog

Hi,

I tried to create and use a custom Recurrence Dialog derived from EditRecurrenceDialog. I've not found a factory like IAppointmentFactory for appointment dialogs so I tried to use the derived dialog directly in the event handler:

private void radScheduler1_RecurrenceEditDialogShowing(object sender,

Telerik.WinControls.UI.RecurrenceEditDialogShowingEventArgs e)

{

e.RecurrenceEditDialog = new My

RecurrenceDialog(e.Appointment);

}

But it always shows the standard dialog layout. What I'm doing wrong?

How to set GridView row header column width / text alignment

Hello,

First, I am starting from this very helpful article: thank you for the recursive solution. VERY helpful: row-header-text

Next, maybe it was asked, how do we set the width of the row header? And/or text horizontal alignment? And/or position of the editor icon(s)?

Because while we're getting the row indexing we're looking for, the icons paint over top of that, or vice versa.

Thank you...

Best regards.

Why RadGrid never delete child row after user deleting parent row?

Please refer the video below
http://www.youtube.com/watch?v=YwCubFXo8bg
From the video, you can see 5 child row record.
After deleting a child row, child row count = 4.
After deleting a parent row, child row count still is 4.

For the source code, please get it from url below
File name is DeleteParentRow.zip
http://sdrv.ms/PU4ZgZ

Auto delete child row function, any way can be done?
Thanks.
