Try this

server Textbox has only the .TextChanged event. You can use the javascript function to handle the keypress. You can specify the function name in the attributes like TextBox1.Attributes.Add("onKeyUp","HandleKeyUp(this)");

Hi duclee,

just in addition to the sukumar_diya, the javascript is case sensitive and the name of the event is onkeyup
