I found a bug in RadMaskedTextInput
My user enters securities(i.e MSFT, NFLX) very fast in textinput and clicks enter which i am handling keyup event.
Here I am making Placeholder=" " because i dont want anything mask in the textinput.
try to enter text very fast and click enter.
1) considering no key up
you can notice the last character gets truncated.
2) handling key up as below code
you get all the text entered but you can see strange behavior when you try to delete it using delete key.
private void xText1_KeyUp(object sender, System.Windows.Input.KeyEventArgs e)
if(e.Key == Key.Enter)
xText1.Value = xText1.Value.ToUpper();
xText1.SelectionStart = xText1.Value.Count();
If you need any further information please let me know.
