There can be only one idea: write it. It's only a few lines. If you face a problem, report it and ask how to resolve it. This is how CodeProject really work.

You can handle the onkeypress event of the textbox. Here[^] is a background on this event.

This[^] is a code sample that demonstrates how to do it.

u can take html textbox for result and use onclick() event like

C++

<input type="text" id="resulttxtbox" name="resulttxtbox" onclick="return sumall()" runat="server" />

and call javascript function to add

XML

<script type="text/javascript">
   function sumall()
   {
   var a=document.getElementById("TextBox1");
   var b=document.getElementById("TextBox2");
   var c= parseInt(a.value)+parseInt(b.value);
   var d=document.getElementById("resulttxtbox");
   d.value=c;
   return false;
   }
   </script>
