    AsyncFileUpload events with Update Panel

    Problem:

     

    Last week I came across this bug (?) with AsyncFileUpload control in updatepanel. The control is not firing OnUploadedComplete server side event when it’s in updatepanel.

     

    Solution:

     

    After doing some research on this issue, came across these solutions.

     

    1)     Add another AsyncFileUpload control on the page and set its’ style to display:none; 

     

           

    <div style="display: none;">

      <cc1:AsyncFileUpload ID="AsyncFileUpload1" runat="server" />

    </div>

     

     

    2)     Another workaround is to add the following attributes to the <form> tag of the page..

    enctype="multipart/form-data" method="post"

     

     

    Both the solutions are working fine.

     

     

    Thanks to obout_teo and MikeMelendez of Asp.Net forums

    It works fine for me but i have to add a few line of code in codebehind.
    In my project when i click button i display the asynfileupload by adding these

      Dim javastr As String = "document.getElementById('AsynFileupload_div').style.display = 'block';"
                ScriptManager.RegisterClientScriptBlock(Page, Me.GetType(), "display", javastr, True)
    where AsynFileupload_div is the div tag that cover the <asp:AsyncFileUpload >.</asp:AsyncFileUpload > tag


    <div id="afu_div"  style="display:none;">
                     <asp:AsyncFileUpload runat ="server" ID="afu_course"  
                     OnClientUploadComplete ="uploadComplete"
                     OnClientUploadError="showUploadError"/>
                </div>
