Hi AbdulHaque,

Refer the below example. FileUpload control requires a full postback in order to get the HasFile property. So use PostBackTrigger.

HTML

<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:FileUpload ID="FileUpload1" runat="server" />
        <asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="Upload_File" />
    </ContentTemplate>
    <Triggers>
        <asp:PostBackTrigger ControlID="btnUpload" />
    </Triggers>
</asp:UpdatePanel>

protected void Upload_File(object sender, EventArgs e)
{
    bool hasFile = FileUpload1.HasFile;
}

It will return true.
