  changing Literal after AjaxFileUpload UploadComplete

  Nov 21, 2012 10:28 AM|LINK

  Hi,

  after the AjaxfileUpload UploadComplete I need to change the text of a Literal inside the page accordingly to the outcome of the upload event. I can't use the usual grafical behaviour of the control because I have a custom check before the SaveAs method (so the AjaxFileUpload could show to the user that the file is successfully uploaded when in fact it has never been saved). 

  There is a way to do so?

  have you tried

  <ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload" runat="server"  UploadedComplete="AjaxFileUploadUploadComplete" ThrobberID="MyThrobber" AllowedFileTypes=""MaximumNumberOfFiles="0" />

  thanks for your reply

  I use the OnUploadComplete event to do my custom check. UploadedComplete is never fired.

  can you post your code behind for the UploadComplete Event?

  This is the code:

  protected void AjaxFileUploadFile_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
  {
     if (myCustomCheck()){
        AjaxFileUploadFile.SaveAs(e.FileName); 
        LiteralResponse.Text = "File saved";
     }
     else
     {
        LiteralResponse.Text = "File not saved";
     }
  }

  Files are correctly uploaded and saved but the literal doesn't change. 

  I think that I have to use the OnClientUploadComplete Event but I don't know how to retrieve the text or the outcome of my custom check.

  I tried to use label and nothing changed. I also tried to get with javascript the text of the label after the UploadComplete event but it's empty.

  The literal is already in an asp UpdatePanel. I have to force a postback after the UploadComplet event to refresh a gridView that is in the updatePanel.

  However I tried to put my literal inside and outside the updatePanel and to change the text without forcing the postback, but the text never appeared.

  <script  type="text/javascript">
      function ajaxFileUploadAttachments_ClientUploadComplete(sender, e) {
          var hidField = document.getElementById("<%=myHiddenField.ClientID %>"),
          hidVal = +hidField.value || 0;
          if (sender._filesInQueue[sender._filesInQueue.length - 1]._isUploaded) {
              __doPostBack('<%= UpdatePanelFileUploads.ClientID %>', hidVal);
          }
      }
  </script>
  <asp:UpdatePanel ID="UpdatePanelFileUploads" runat="server" UpdateMode="Conditional" OnLoad="UpdatePanelFileUploads_Load"><ContentTemplate>
          <asp:HiddenField ID="myHiddenField" runat="server" Value='<%# FieldValueEditString %>'></asp:HiddenField>
          <asp:PlaceHolder ID="PlaceHolderFiles" runat="server">
                          <asp:GridView PagerSettings-Visible="true"  ID="GridViewFiles" runat="server" AutoGenerateColumns="False"
                              DataSourceID="SqlDataSourceFileCaricati" AlternatingRowStyle-CssClass="odd"
                              HeaderStyle-CssClass="headerTable"  CssClass="gridLight" ShowHeader="false" ondatabound="GridViewFiles_DataBound">
                              <Columns>
                              </Columns>
                          </asp:GridView>
                          <asp:SqlDataSource ID="SqlDataSourceFileCaricati" runat="server"
                              ConnectionString="<%$ ConnectionStrings:SoluzioneWebConnectionString %>"
                              SelectCommand="" >
                          </asp:SqlDataSource>
          </asp:PlaceHolder>
          <ajaxToolkit:AjaxFileUpload runat="server" ID="AjaxFileUploadFile" OnClientUploadComplete="ajaxFileUploadAttachments_ClientUploadComplete" OnUploadComplete="AjaxFileUploadFile_UploadComplete" />
  	<asp:Literal ID="LiteralMessaggioRisposta" runat="server"></asp:Literal>
  </ContentTemplate></asp:UpdatePanel>

  My code is a web user control for a fieldTemplate in a Dynamic Data web site.
