Hello all,

if i try to upload other file except pdf should give alert and need to remove selected path
<asp:FileUpload ID="FileUplod1" runat="server" Height="18px" onclientclick="CheckFile(this);" />
function CheckFile(Cntrl) {
var file = document.getElementById(Cntrl.name);
var len = file.value.length;
var ext = file.value;
if (ext.substr(len - 3, len) != "pdf")
{
alert("Please select a doc or pdf file ");
