Solution 1

function onkeydown(){
     var ch = String.fromCharCode(event.keyCode);
     var filter = /[a-zA-Z]/   ;
          event.returnValue = false;
This can restrict the user to input only characters, but you still have to consider that user can paste numbers, or drag in into textbox.

Solution 2

Use event.keyCode to accept only char values.
write a function in javascript and call it on onkeypress event of Textbox

function checkNum()
if ((event.keyCode > 64 && event.keyCode < 91) || (event.keyCode > 96 && event.keyCode < 123) || event.keyCode == 8)
   return true;
       alert("Please enter only char");
       return false;
