Selecting RichText Hyperlink in a ChildWindow crashes Silverlight

[Ben]

I have tracked down a bug i was receiving to an interesting case.  I have a RickTextBox which users can add a Hyperlink to, everything works fine, but when the user selects some text and while selecting they hover over the link the tooltip displays.  When you move the cursor more from there you get a COM Exception.

This only occurs when the textbox is inside a ChildWindow, removing the tooltip is an acceptable solution, but I don't know if I can do that that.  Any help would be greatly appreciated.  Attached is a screenshot.

Error:
    Error HRESULT E_FAIL has been returned from a call to a COM component.

Hi Ben,

I tried to reproduce your error, but was unsuccessful. I have put a RadRichTextBox in a ChildWindow, inserted a Hyperlink through the InsertHyperlinkDialog, selected things around and moved the cursor randomly, but did not get an exception. Can you think of anything I should be do differently? Can you please also confirm which version of RadRichTextBox are you using? Did you try the same scenario using Q3 Beta?
It would be even better if you could send a demo, which illustrates the error.

Kind regards,

Let me try it with the Q3 Beta.

Hi Ben,

We managed to reproduce the issue. It seems that the tool-tips fire a bug in Silverlight. We will review our code to try to workaround this limitation.

If you have any other concerns, do not hesitate to contact us again.

Kind regards,

   I have the same error when trying to double click in richtextbox to edit the header. Was this bug ever fixed? What would be the walk around?

Hello Dennis,

This bug that Dan reported appeared in Q2 2010 and was fixed a long time ago.

Could you provide some more details on the version of the controls you are using, e.g. 2011.3.1220.1050 or 2011.3.1116.1040, as well as steps to reproduce the problem, because the issue is probably not related to the one a year ago. Please, do not forget to mention the version of Silverlight you are using - SL4 or SL5.

All the best,
