Question

Am trying to copy the content of a Richtextbox to another Richtextbox using the below code.

FlowDocument doc = RTB1.Document;
RTB1.Document = new FlowDocument();
RTB2.Document = doc;

But the copied line disappears if i try to save the screen where the RichTextBox(RTB2) is there.

Any help on this will be greatful.

Answer 1

After copying the content from one RichTextBox to another the content used to disappear because the focus was not coming back to the copied RichTextBox.

So the solution i used was to set the focus of RichTextBox2 after copying.

 FlowDocument doc = RTB1.Document; 
 RTB1.Document = new FlowDocument(); 
 RTB2.Document = doc; 

 RTB2.Focus();
