Hi

We're using the WPF viewer, and everything has been great. I need to detect keyboard ctrl+s in order to save the document. I can detect it find for most places, but it seems the keyboard events don't raise if the focus is on a checkbox or radio button form field (it works for a text box fine).

Just hoping there is a way that we can capture the keyboard event here, or if there is any known way in the viewer/document to respond to a ctrl+s event to save the document?

Thanks

I have checked on my document the following

Code:

        protected override void OnPreviewKeyDown(KeyEventArgs e)
        {
            base.OnPreviewKeyDown(e);
        }

Keystrokes are intercepted without any problems. Could you please provide your document and code.
Although I'm sure that the document does cannot affect to the standard UIElement

Oh yep. Thanks! I was hooking into the OnPreviewDown event rather than overriding it. That works. Cheers
