FileUpload.HasFile() always null

Anonymous User 2682 03 Sep 2014

This is the code I use for my UpdatePanel.

The FileUploadAsync.HasFile() is always null.

I am wondering what is wrong with my asp.net page ...

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="Server" />
<asp:UpdatePanel ID="UpdatePanelAddFiles"runat="server" UpdateMode="Conditional">
    <Triggers>
       
<asp:AsyncPostBackTrigger ControlID="LkUpload" />
    </Triggers>
   
<ContentTemplate>
    <asp:LinkButton ID="LkUpload" runat="server" OnClick="LkUpload_Click"
Visible="false">Upload</asp:LinkButton>
        <ajaxToolkit:AsyncFileUpload runat="server" ID="FileUploadAsync" />
   
</ContentTemplate>
</asp:UpdatePanel>
