<script language="javascript" type="text/javascript">
function ClearFileUploadControl() {
var uplctrl = document.getElementById("fileupload1");
uplctrl.select();
clrctrl = uplctrl.createTextRange();
clrctrl.execCommand('delete');
uplctrl.focus();
}
</script>
</head>
<body>

<table><tr>
<td><b>Upload Images:</b></td>
<td><asp:FileUpload ID="fileupload1" runat="server" /></td>
</tr>
