Enclosed you will find the example.

Hi Roman,

I have been looking into your requirement and you can handle the ‘SelectedItemChanged’ event and set the selection length to “0” like e.g.:

        private void XamComboEditor_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)

        {

            Dispatcher.BeginInvoke(new Action(() =>

            {

                (sender as XamComboEditor).SelectionLength = 0;

            }), System.Windows.Threading.DispatcherPriority.SystemIdle, null);

        }

Let me know, if you need any further assistance on this matter.

Thank you for your answer.

But now the autocomplete function is no longer available. (just for the first character)

Hello Roman,

After further research on the matter I made a little modification to the project that you have attached to scroll horizontally to the beginning of the text and to keep the selection at the same time. This could be achieved by using the TextBox element that is part of the editor and call the ScrollToLine method every time the selection is changed (that will happen when user enters characters).
I hope this approach will help. Let me know if you have any other questions or concerns.

Hello Roman,

I am just checking if my last reply was helpful for you.

If you require any further assistance, please do not hesitate to ask.

Hallo.

Yes ist works, but this is just a workaround, because sometimes i have to wait after the selection is correct aligned or i see the caracters "flickering".

Best regards,

Roman
