JavaScript runtime error: Sys.InvalidOperationException: Two components with the same id 'mpeAttachment' can't be added to the application.
But i use different types of ID only for modal Popup mpeAttachment and mpetimeout
Anybody Please Solve this issue
<asp:HiddenField runat="server" ID="HiddenAttachment" />
<asp:ModalPopupExtender ID="mpeAttachments" PopupControlID="pnlAttachments" runat="server"
CancelControlID="lnkExit" TargetControlID="HiddenAttachment" BackgroundCssClass="modalBackground">
</asp:ModalPopupExtender>
<asp:Panel runat="server" ID="pnlAttachments" CssClass="modalPopup" Style="width: 456px;
height: 266px;">
<table width="100%">
<tr>
<td class="blankrow">
</td>
<td>
</td>
</tr>
<tr>
<td style="font-size: 20px; font-style: normal">
File Attachment
</td>
</tr>
<tr>
<td class="blankrow">
</td>
<td>
</td>
</tr>
<tr>
<td>
<asp:Label runat="server" ID="lblbrowse" Text="Step 1- click browse to select a file from your computer" />
</td>
</tr>
<tr>
<td>
<%--<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:FileUpload ID="FileUploadControl" Style="width: 445px;" runat="server" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="btnUpload" />
</Triggers>
</asp:UpdatePanel>--%>
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblAttachmentDescription" runat="server" Text="Step 2- give me a brief description of this file" />
<asp:Label ID="lblErrorMessage" runat="server" Visible="false" Style="float: left;
color: red;"></asp:Label>
</td>
</tr>
<tr>
<td>
<asp:TextBox runat="server" Width="442px" ID="txtAttachmentDescription" />
<%--<asp:RequiredFieldValidator runat="server" id="valid1" ControlToValidate="txtAttchmentDescription" ErrorMessage="enter" />--%>

</tr>
<tr>
<td align="center">
<asp:LinkButton ID="lnkExit" runat="server" Text="Cancel" Font-Underline="true" Style="color: Blue;" />

<table width="100%">
<tbody>
<tr>
<td align="center">

</td>
</tr>
<tr align="center">
<td>
Your session have been idle for some time now.<br />
For security purpose the session will be terminated in <span id="myCounter" style="color: Red">
</span>seconds.
<br />
If you want to continue, you should save the data otherwise select logout.
</td>
</tr>
</tbody>
</table>
<table width="100%">
<tr align="center">
<td>
<asp:Button runat="server" Text="Logout" ID="btnSessionNo" />
<asp:Button runat="server" Text="SaveData" OnClientClick="return myStopFunction();"

</td>
</tr>
</table>
