Keeping focus on the Dialog even when user presses Tab Posted: May 17, 2010
 

Hi Dan.


I'm calling ShowAsModal(). Once the dialog is open, there's no way for the user to click any UI elements outside the dialog, which is good. I just noticed that if the user presses the Tab key, he can loop through the browser address bar and browser buttons (expected and okay), AND all the other UI Elements in my window, i.e., even the elements that should be 'behind' the dialog, thereby circumventing the modal behavior.


Have I forgotten to set something?

Hi Ken,


Thanks for pointing this out.  The default behaviour when for modal dialogs is to render a transparent element over the background which as you've seen doen't stop the user tabbing between controls.


The solution for this is to use the DisableBackground and EnableBackground events and in your code set the IsEnabled state on the controls that should be disabled whilst the dialog is visible.  When there are many child controls it may be a good idea to place them all in a ContentControl wrapper and just toggle the IsEnabled state of that.


Thanks!
