java function when the button is clicked? If so, please provide
example.....thanks.,

<head>
<script language="VB" runat="server">
Sub Page_Load( sender as Object,e as EventArgs)
'Form the script that is to be registered at client side.
Dim scriptString as String = "<script language=JavaScript> function
onClientClick() {"
ScriptString += "var retVal = window.confirm('Click OK to continue.
Click Cancel to stop.');"
ScriptString += "window.alert(retVal);"
ScriptString += "if (retVal){"
ScriptString += "window.alert('MVP Code is doing the Postback!');"
ScriptString += "return true;"
ScriptString += "}"
ScriptString += "else"
ScriptString += "{"
ScriptString += "window.alert('MVP Code is NOT Doing the
Postback!');"

If(Not IsClientScriptBlockRegistered("clientScript"))
RegisterClientScriptBlock("clientScript", scriptString)
