Here is the solution

 $("#Partner").keydown(function (e) { if (e.keyCode == 90 && e.ctrlKey) { e.preventDefault(); return; } }); //key up handles all keypresse events. Backspace wont fire for simple keypress event in jquery $("#Partner").keyup(function (e) { if (e.keyCode == 90 && e.ctrlKey) { e.preventDefault(); return; }

Try this...

$("#Partner").bind("keydown", function (e) { if (e.keyCode == 90 && e.ctrlKey) { e.preventDefault(); return; } }

Note: the key operations are performed in the keydown operation also. so try to prevent the keydown event to block the default behavior.
