Hi Shankey Thanks for soon reply and i alos want to know that on keypress i have done a validation for brackets '(' and ')' but i am not able to enter thie this cuz keypress event does not allow to press shift+( so what is the ascii value of shift key.

Shankey · Answer

hi To check ctrl + alt + delete key u have to check key code instead of ascii value if (e.KeyCode == Keys.Control) { if (e.KeyCode == Keys.Alt) { if (e.KeyCode == Keys.Delete) { CancelEventArgs cancel = new CancelEventArgs(true); } } }
