Using Sendkes.Send function in WPF

Question

I have a wpf application. In my TextBox, I want when user press "Enter" key, focus jumps to next tab index control, like pressing tab key, I use this code

if (e.Key == Key.Enter)
{
     SendKeys.Send("{TAB}");
}
if (e.Key == Key.Escape)
{
     SendKeys.Send("+{tab}");
}

but this doesn't work. could you please help me?

You need to use the TraversalRequest:

if (e.Key == Key.Enter)
        {
            TraversalRequest tRequest = new TraversalRequest(FocusNavigationDirection.Next);               
            UIElement keyboardFocus = Keyboard.FocusedElement as UIElement;

            if (keyboardFocus != null)
            {
                keyboardFocus.MoveFocus(tRequest);
            }

            e.Handled = true;
        }           

The TraversalRequest takes the FocusNAvigationDirection as its parameter, determining the direction in which you want to navigate.

Also, this is the MSDN on traversalRequest class.
