There is a typical problem in using KeyCode value & String.fromCharCode. If i use this i always get characters in CAPITAL. Also I get some different symbol if i type characters like full-stop comma. Please help! I need to get the exact character in my code that the user keyed-in the textbox.

This is what I think you need to do: First you need to add attribute to that textbox to execute KeyDown function on key down like this: (page_load) txt1.attributes.add(onKeyDown javascript:KeyDown(event);); function KeyDown() { if(window.event) // IE { keynum = e.keyCode } else if(e.which) // Netscape/Firefox/Opera { keynum = e.which } keychar = String.fromCharCode(keynum); NavigateId(keychar); } HTH. Happy Programming!!! Regards Raja

Well textbox.text will return the complete text in the textbox. I need only the character that the user keyed-in in the textbox.

Aman Ghai · Answer

No I can't do that. You probably misunderstood my requirement. I need to know each character as the user type in this multiline textbox & do some processing with that character. So my KeyUp event should somehow tell me the character that the user just typed in the textbox. Please help in this regard! Thanks Amandeep

Hi aman Instead of using keyup event  try with textBox_Leave event that is just bcz of keyup will fire everytime and u will not get the whole text of textbox which user has entered. and then pass textbox.Text to your javascript from this textBox_Leave event
