How to save a file from HTML File Control in AJAX Section Using ASP.Net with C#



    •     AJAX stands for Asynchronous  Java script and XML  
    •    AJAX enable a page asynchronously post back a page.  
    •   Only required part load from server instead of entire page so its   increase web performance.
    • Some control which are design for post back like file browser which can’t load a file if its not post back so you can’t upload a file when it’s in AJAX section.

        For upload a file in AJAX section using file browser you need to register a button for post back if user will click on than button then all page will be reloaded.
      <asp:UpdatePanel ID="U1" runat="server">
                <ContentTemplate>
      ....................................
      ....................................
               </ContentTemplate>
         <Triggers> 
             <asp:PostBackTrigger ControlID="saveButton">
         </Triggers>  
      </asp:UpdatePanel>
