keypress handling

I need to implement keypress handler that works anywhere on a form (actually so long as I am on one of several tab pages on my form which is basically a tab control with 4 pages. Here is the problem - my TabControl.Keypress handler intercepts the keypress only of one of the grids on that same tab does not have focus. Essentially, once I select a row on a grid, my handler no longer receives keypresses, as they are now aparently directed to the selected grid. The handler is invoked if I am editing one of the edit controls. How can I intercept ALL keypresses within the form/tab page? Do I have to resort to the windows message handler?

Did you set the form's 'KeyPreview' property to 'True'?
 
Have you tried setting the Form's KeyPreview property to true?
