    Upload Dialog box is not opening in IE7

    Reply Quote
    Hello:
     
     
    With the new version of the AjaxUploader DLL, we are experiencing some new errors.
     
    1. The clicking of the main upload button causes an automatic post back. However, we resolve this with the CausesValidation set to false.
    2. Using the CausesValidation = false causes the upload button not to open the dialog box when clicked. This only happens in IE7. All other browsers work fine.
     
    Regards,
    Dennis Gilgallon

       thanks. I think this is an isolated issue with my IE 7. It may have been a patch I installed as other web sites are functioning the same way.

       We have isolated this issue. We have performed a few tests to confirm this. We believe the error is coming from Flash 10.a plugin for IE.
     
    In your control, there is a setting for Upload type. This is by default set to Auto. I am assuming that this does a check for the plugins. If the plugin is found, it uses Flash or Silverlight. If it is not, IFrame is used.
     
    This is how we tested.
     
    1. Determined which machines were seeing this error.
    2. Checked all machines to see if they has Shockwave/Flash installed and enabled on IE7
    3. Matched that machines without the plugin or diabled plugin were working properly while those that had it installed and enabled were not working.
    4. We disabled the plugin on all machines and tested the button. The button works fine at this point.
    5. Further, we tested the UploadType by changing this from Auto to IFrame. We then tested the site with all computers (both with and without the plugin enabled) and the button works fine.
     
    Note: We did not specifically test setting the UploadType to Flash or Silverlight.
     
     
    Can you let us know when a fix is set for this.
     
    Regards,
    Dennis Gilgallon

      I am unable to produce the error on your demo. Is your demo running the 1.1 .Net foundation? I suspect that it is running 2.0 or higher. Our demo is running the 1.1 .Net foundation
     
    This could be the problem
     
    We currently have the uploadtype set specifically to IFRAME to avoid the error. However I will swicth this back to AUTO.
     
    In addition, when uploading larger images (1000K + ) we get a javascript error about Task is not defined. This is something that is in the back end of the code that we can not access. I believe this is in the validation code.

    Dennis Gilgallon,
     
    We have found that the validation would generate script for the button's javascript onclick function.
     
    And that function would cause the page postback.
     
    So please try to use this code :
    <script runat="server">
     protected override void OnInit(EventArgs e)
     {
      base.OnInit(e);
      Uploader1.InsertButton.ValidationGroup = "NoValidation";
     }
    </script>
     
    Regards,
    Terry

       Do I need to download the DLL again from you? The ValidationGroup does not seem to be part of the InsertButton (atleast not in the intellisense)

    Hello, my fileuploader worked fine up until I performed the upgrade that flash player requested this morning. I have to set all of my fileuploader controls to IFrame to get a dialog box to open.

    Perhaps now they may agree that there is an issue with the new flash player and their control.

    Dennis,
     
    You need not download it again. But we recommand you download it.
     
    The Uploader.Button is an instance of class System.Web.UI.WebControls.Button.
     
    If you are using ASP.NET2.0, you should use the ValidationGroup property : http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.button.validationgroup(VS.80).aspx
