Hi Georgi,
I attached to this post a sample to show you how I got the sync scrolling using two RichTextBoxes and, as you can see in the project, the same code doesn't work with UltraFormattedTextEditors. I couldn't find a solution, but maybe you can find a way to make it work.

Thanks
Stefano

Hi Georgi,
I may give up on using UltraFormattedTextEditor this time, I found an acceptable solution using classic RichTextBox and Win API.
However, Thank you for your time.

Hello Stefano,

Maybe you could try to use PerformAction method. For example:

private void ultraFormattedTextEditor1_VScroll(object sender, ScrollEventArgs scrollEventArgs)
{
    ultraFormattedTextEditor2.PerformAction(FormattedLinkEditorAction.Down, false, false);
}
 
private void ultraFormattedTextEditor2_VScroll(object sender, ScrollEventArgs scrollEventArgs)
{
            
    ultraFormattedTextEditor1.PerformAction(FormattedLinkEditorAction.Down, false, false);
}

Please let me know if you have any questions

Regards

Hi Georgi,

your sample solution works fine, but there is one problem: if I scroll the left textEditor, the right one scrolls too, but it doesn't show the text and "ultraFormattedTextEditor.Refresh();" is not sufficient to do it. To make it easer to verify, I just modified your sample enlarging the textEditors and adding some text. Thank you for your support.

Regards

Stefano
