Hi, I have a user control that extends RichEditBox, we have a TextChanged Property, we bind a string variable to the Text Property, and the error shown in the image is generated within the TextChanged function, I am not sure why this error is being generated.. Any clue would be helpful.
For further information, Document.Selection is not null, Document.Selection.Text does show the last string bound to it, TASK_DONE_SYMBOL is not null either.
We have a page with a lot of items, each item has a RichEditBox, and when we update some of the items, sometimes, not always, does this issue come up.
