Crash when delete all content in Rich Textbox

[vinay kumar]

Hi

 

i am dynamically adding spans to a richtextbox when user click on a button.

 

   foreach (var item in objspanList)
                {
                   
                   
                   this.richTextBox.InsertInline((Telerik.Windows.Documents.Model.Inline)item);
                }

Its getting added as expected.  But when i add couple of times and then try to delete  all , application gets crashed and unhandled exception is thrown. So not sure on the error.

 

Can you please suggest on this.

Hi,

I tried to reproduce the issue but to no avail. Adding spans dynamically and then deleting all worked and no exceptions were thrown. Could you elaborate more on your scenario. A sample reproducing the issue will help is isolate the problem and provide you with a possible solution.
