    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.
