How to know when ctrl+space pushed?

Question

I want to call function when Ctrl+space pushed. I searched more but couldn't find what I want.

Answer 1

You need to add an event handler for KeyDown like: KeyDown="TextBox_KeyDown" on your TextBox. And then in the event handler:

if (e.Key == Key.Space && e.KeyboardDevice.Modifiers == ModifierKeys.Control)
{ 
      //Do Stuff
}

Answer 2

Use something like this:

private void Window_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.Space && 
       (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
    {
        // Do what you need here
    }
}
