  AjaxControlToolkit.AsyncFileUploadEventArgs UploadedComplete gets fired twice

  Jul 12, 2012 09:29 PM|LINK

  Hi

   

  The UploadedComplete for the AjaxControlToolkit.AsyncFileUploadEventArgs gets fired twice (code below)

  I have looked on google and it seems this is a common problem but there is no solution that I have found. Can anyone help or is this a bug?

  Thanks

  java:

  <

  script type="text/javascript">

     

  function uploadComplete() {      //Postback is necessary for asyncfileupload 

          __doPostBack(

  'upFiles', '');

      }

  </

  script>

  .aspx code:

   

  <

  tr>

  <

  td class=formRight>Attach File(s):</td>

  <

  td class=formLeft>        <table class=formTable>

         

  <tr>

         

  <td class=formLeft><asp:AsyncFileUpload ID="AsyncFileUpload1" onuploadedcomplete="UploadedComplete" OnClientUploadComplete="uploadComplete" runat="server" ThrobberID=throbber CompleteBackColor="#ccff99" /></td>

         

  <td class=formleft><asp:Label ID="throbber" style="display:none" runat="server"><img align="absmiddle" alt="loading" src="../../Images/ajax-loader.gif" /></asp:Label></td>

         

  </tr>

         

  <tr>

         

  <td class=formleft colspan=2>

         

  <

  asp:UpdatePanel ID=upFiles runat=server>

  <

  ContentTemplate>

  <

  asp:GridView runat=server ID=gvFiles AutoGenerateColumns="False" GridLines=none  borderColor="#ece9d8" ShowHeader=false>

  <

  RowStyle cssclass=gvRows/>

  <

  Columns>

  <

  asp:TemplateField>

  <

  ItemTemplate>

  <

  asp:Label ID=lbFileName runat=server Text='<%# Eval("FileName")%>'></asp:Label>&nbsp;

  </

  ItemTemplate>

  </

  asp:TemplateField>

  <

  asp:TemplateField>

  <

  ItemTemplate>

  <

  asp:imagebutton id=ibDelete runat=server CommandArgument='<%# Eval("FileName")%>' CommandName="DeleteFile" ImageUrl="~/Images/RedCross.gif" CausesValidation=false></asp:imagebutton>

  </

  ItemTemplate>

  </

  asp:TemplateField>

  </Columns>

  </

  asp:GridView>

  </

  ContentTemplate>

  <Triggers>

  　

    

  <asp:PostBackTrigger ControlID="gvFiles" />

             

  </Triggers>

  </

  asp:UpdatePanel>

         

  </td>

         

  </tr>

         

  </table>

  </

  td>

  </

  tr>

   

   

  and vb code:

   

     

  Sub UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs)

  System.Threading.

  Thread.Sleep(250)

         

  If (AsyncFileUpload1.HasFile) Then

             

  Dim strPath As String = System.IO.Path.GetFileName(e.FileName)

              AsyncFileUpload1.SaveAs(Server.MapPath(

  "..\..\Files\" + Master.AccountId + "\ArticleFile\" + ViewState("ArticleGuid").ToString + "_" + strPath))

             

  GeneralFunctions.saveArticleFile(Master.AccountId, strPath, ViewState("ArticleGuid").ToString)

              getFiles(strPath)

         

  End If

     

  End Sub

  Hi Thanks but none of the links solve the problem of the event firing twice. I can only assume this is a bug with the asyncfileupload event?

  Hello

  I see you have uploadComplete for the client side event after uploaded successfully. In this function, you make an __doPostBack call to the server. So it is likely that UploadedComplete is called first time, and then the __doPostBack makes it called again.

  Thanks for this but I'm not sure that is the problem. The  _doPostback just postbacks an update panel containing a list of the uploaded files. It doesn't contain anything else.
