0	user below code to call that function in keypress event. To Use below code you need to add jquery reference file. $(document).ready(function () { $(<%=TextBox1.ClientID%>).keypress( function(event){ validateNumbersOnly(event);} ); }); Jigar Bagadai Shanky11, if this helps please login to Mark As Answer. \| Alert Moderator
