Hey guys hope you enjoy this simple video, I made this one so that I can answer the question about my previous video on textbox validation wherein they are not able to use the back space.
Thanks guys

Good Job ... But , in addition to denying the user from typing the wrong input ( number or text), it is good if we can also notify them by displaying message ... i said this because people my enter input in a user name text box for example , i may type myid56 , the system will read only letter and ignore the digits , if i did not notice this and move quickly .. i feel my user name is myid only and i may not log in, especially if i was doing signup ...

Hi my friend
more easier is: e.Handled = !( char.Isnumber(e.Keychar) || e.Keychar == 8 || e.Keychar ==32) ;
You don t need short hand expression at all :-)
Try it !
