Hi,

We have an office word template project which opens up a wpf form when the user tries to launch it. 

The WPF form has one or more telerik Richtextbox controls. When the user start typing inside the textbox they get the above error.
ie."The dispatcher process has been suspended,but messages are still being processed.".

Even though this error occurs more when user tries to type fast inside the textbox, there are cases this happened even otherwise.

There is no event in our code that gets fired on TextChanged or anything similar.

Has anyone else experienced this?  Could someone help me to resolve this?

Many thanks,

Anu

Hi Anu,
We were not able to reproduce the issue. Any additional information may help us track it:
  • Does your scenario include some special setup?
  • Could you reproduce the problem in simple project, containing only RadRichTextBox?
  • Are you able to reproduce the problem consistently - i.e. with some specific steps?
  • What is the version you are using?

Regards,

Hi Boby,

Thank you very much for your reply. I didn't attempt to reproduce this in a simple project - this is something I am planning to do next.

This problem occurs when I try to type in text very fast. I googled on this and can see that a lot of people are getting similar issues - but mostly when there is an event that gets fired. Here in my case there is I am not attaching any events.

We are using RadControls for WPF Q3 2011 SP1.

Thanks again,

Anu

Hi Anu,
We were not able to reproduce the issue you mentioned. The version you are using is rather old and RadRichTextBox has evolved a lot since then; we would advice to try upgrading to newer version of the control and check if the issue is reproducible there. If the problem persists, please try to isolate it in a sample project and send it to us for further investigation.
