How to forbid backspace key in WPF
How can I forbid the Backspace-Key as easy as possible in a WPF-Application?
The KeyDo开发者_运维知识库wn-Event don't catch at the DEL and the Backspace-Key.
Thank you!
To handle Backspace or other pressed key in order to cancel it, try to use the "PreviewKeyDown" event handler.
In your Xaml, set the attribute PreviewKeyDown like this :
<TextBox PreviewKeyDown="textBox1_PreviewKeyDown" ...
and in your code, define the event handler like this :
private void textBox1_PreviewKeyDown(object sender, KeyEventArgs e)
{
if (e.Key == Key.Back || e.Key == Key.Delete)
{
e.Handled = true;
}
}
Hop that helps :)
Try overriding OnTextInput(...)
.
Then if(args.Text == "\b")
should give you the backspace.
