sad

you can use FileUpload control inside UpdatePanel .

Check the code below

<asp:UpdatePanel ID="upnlMain" runat="server" UpdateMode="Conditional">

           <Triggers >

           <asp:PostBackTrigger ControlID="btnSubmit" />

           </Triggers>

               <ContentTemplate>

              <table>

                  <tr>

                   <td>

 <asp:Image ID="imgPhoto"  runat="server" AlternateText="Photo" Height="100px" Width="100px"

BackColor="Silver" BorderColor="Black" BorderStyle="Solid" ImageAlign="Middle" />

</td>

</tr>

<tr>

<td>

<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click"/>

</td>

</tr>

in Code behind file

 protected void btnSubmit_Click(object sender, EventArgs e)

   {

       try

       {

if (FilePhoto.HasFile)

           {

 HttpPostedFile img= FilePhoto.PostedFile;

/* code as per your requirement */

}

       }

       catch (Exception ex)

       {

          throw new Exception(ex.Message.ToString());

       }

   }
