DataForm containing RadRichTextBox automatically cancelling edit on load

[Georges Nguyen]

I have a DataForm that contains a RadRichTextBox and whenever I view the DataForm with AutoEdit="True", the DataForm is automatically cancelling the edit. If I set AutoEdit="False" and then click the edit button myself, there is no problem, and if I remove the RadRichTextBox, there is also no problem. But I would like both. The call stack at the EditEnding event is:

> ~My Code~(object sender, System.Windows.Controls.DataFormEditEndingEventArgs e) Line 64 C#
  System.Windows.Controls.Data.DataForm.Toolkit!System.Windows.Controls.DataForm.OnItemEditEnding(System.Windows.Controls.DataFormEditEndingEventArgs e) + 0x46 bytes 
  System.Windows.Controls.Data.DataForm.Toolkit!System.Windows.Controls.DataForm.CancelEdit() + 0x78 bytes 
  System.Windows.Controls.Data.DataForm.Toolkit!System.Windows.Controls.DataForm.OnContentRootElementLostFocus(object sender, System.Windows.RoutedEventArgs e) + 0xa4 bytes 

I am using Q3 2010 SP1.

Hi Georges Nguyen,

The issue seems to be with the way RadRichTextBox handles focus internally. It uses a TextBox for its caret and whenever the editor receives focus, it passes it to the TextBox. However, the DataForm obviously doesn't work correctly in that case. We'll definitely research the possibilities, but unfortunately, there's no workaround currently.

Hello Georges Nguyen,

We are in process of investigating the problem again, and cannot reproduce it with 2010 Q3 SP1 nor with 2011 Q1 version. I am attaching a sample project (built against  Q3 SP1 version) to verify at your side.
It would be much appreciated to send us a sample project that reproduces the issue, as there are various ways to customize data forms to include RadRichTextBox.

Best wishes,

The bad behavior seems to occur when the DataForm is bound to an WCF RIA Services Entity object. The DataForm seems to have some special behavior for those objects or one of the interfaces it implements, at least that is my guess. I will work on creating a sample project with the problem, but I'm only familiar with using Domain Services backed by LINQ to Entities and I don't know if that would be appropriate for a sample project.

I've also discovered the bug only appears when in a Child Window. I have been able to reproduce it now, but I am unable to attach .zip files to this post. Is there another way I can send a sample project?
