You need to handle the onmousemove and onclick event of your panel in
JavaScript.
I've attached an example in C# (should be easy to convert to VB.net).
the getPanelMouseCo Ords JavasScript sets two text boxes (so you can see
it in action) and two hidden fields with the mouse postion.
The onclick handler just submits the form.
When the form is posted back to server the PageLoad extracts the values
from the two hidden form fields and sets the label for info
It works in IE but may ntyo work in other browsers:
Webform1.aspx:
<%@ Page language="c#" Codebehind="Web Form1.aspx.cs"
AutoEventWireup ="false" Inherits="Panel MousePosition.W ebForm1" %>

<body>
<form id="Form1" method="post" runat="server">

<script language="JavaS cript">
function getPanelMouseCo Ords()
{
var mouseX = event.clientX + document.body.s crollLeft;
var mouseY = event.clientY + document.body.s crollTop;
document.Form1. xPos.value = mouseX;
document.Form1. yPos.value = mouseY;
document.Form1. hidX.value = mouseX;
document.Form1. hidY.value = mouseY;
return true;
}
function handlePanelClic k()
{
document.Form1. submit();
}
</script>
</form>
</body>
</HTML>
and there's the code behind to register and handle events
(WebForm1.aspx. cs):
