RichTextBox MVVM scroll to end

[Eric]

Hi -

I am currently using a trial of the Telerik WPF products and so far I am impressed.

I'm using a RichTextBox and I am data binding it into my ViewModel using the subclass I found on your forums which uses the HtmlFormatProvider and a RichText dependency property. This particular text box has text added to it regularly. I would like to keep the scroll bar scrolled to the bottom so you can always see the last line of text added to the text box and I'd like to do it with data binding if possible so that I don't break my MVVM. What would be the best approach?

Thanks!

Hello Eric,
You can use ScrollToVerticalOffset method to scroll to the bottom (for example, when RichText property changes its value):

this.radRichTextBox.ScrollToVerticalOffset(double.MaxValue);

You can use attached behaviors (from the Expression Blend SDK) if you want to avoid using code-behind in this case.

Don't hesitate to contact us if you have other questions.

All the best,
Boby
