I have an Winforms application that is using a WPF control (Avalon Edit if it matters) inside an ElementHost.
It seems to be working fine, but I would like to be able to handle KeyPress events of this control in the Winforms manner (without RoutedCommands and InputGestures), so I though I could just handle the Form's KeyDown event with KeyPreview set, but WPF events don't seem to bubble up to the Form.
So 开发者_如何学编程basically, how can you access a KeyDown event on a WPF control in the Winforms manner?
You can try to add custom event handler for WpfControl itself, instead of trying to connect to WinForm's KeyDown.
Here's example. Let's say: your WinForm is of type Form1
, WpfControl is UserControl1
, and element host for WpfControl is called (won't ever guess)) - elementHost.
public Form1()
{
InitializeComponent();
elementHost.ChildChanged += ElementHost_ChildChanged;
}
private void ElementHost_ChildChanged(object sender, ChildChangedEventArgs e)
{
var ctr = (elementHost.Child as UserControl1);
if (ctr == null)
return;
ctr.KeyDown += ctr_KeyDown;
}
void ctr_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
/* your custom handling for key-presses */
}
UPD: e.KeyboardDevice.Modifiers
(e is System.Windows.Input.KeyEventArgs
) stores info about Ctrl, Alt, etc.
