Hello,
when I put the FormulaEditorDialog inside of any scroll viewer child controls and set its HorizontalScrollBarVisibility to Auto the above described problem occurs. I attached a simple sample for demonstration.
Hello Marcel,
Our developers said that since the FormulaEditorDialog uses a derived RichTextBox, this behavior is expected because the RichTextBox itself behave like this. The thing you can do to workaround this is either set the Width of the FormulaEditorDialog or turn off the HorizontalScrollBarVisibility. Please let me know if you have further questions on this matter.
Looking forward for your.
