    [CLOSED] submitting file to ashx in IE browser

    IE popups a dialog to save a json file in the example bellow.Which is not true in other browsers
          <ext:FormPanel runat="server" ID="frmUploadImage" Layout="HBoxLayout" AnchorHorizontal="100%" BodyStyle="background-color:transparent" Border="false" Url="~/handlers/project_images.ashx/saveNewImages">
        <Items>
              <ext:FileUploadField runat="server" ID="fufImageUpload" AllowBlank="false" ValidateBlank="true" Text="" Name="fileUpload"  Width="400" LabelWidth="125">
               </ext:FileUploadField>
             <ext:Button runat="server" ID="btnSaveImage" Text="Upload" Icon="DiskUpload" Flat="false">
                 <Listeners>
                   <Click Handler="Ext.getCmp('frmUploadImage').getForm().submit() ">
                   </Click>
             </Listeners>
            </ext:Button>
 </ext:FormPanel>
    the handler returns 
      msgBox.Show(new MessageBoxConfig()
                {
                    Icon = MessageBox.Icon.ERROR,
                    Message = "Images size exceeds maximum allowed (1MB)!!!",
                    Title = "Project Images",
                    Fn = new JFunction { Handler = "mssoc.templates.fn.setFileUploadCaption();Ext.getStore('storeImageManagement').load();" }
                }
 return new DirectResponse(msgBox.ToScript());
    In non IE browsers the messagebox box displays just fine but in IE it popups a dialog to download the json file.The content type is set correctly "application/json";

    Hi @odyssey,

    I think the IsUpload="true" setting might be required for a DirectResponse.

    IsUpload

    Well then the script is not being executed at all .It wrap ups the script in textarea tag

    It appears that it is a known IE issue when it tries to "download" an "application/json" response.

    Yes, IsUpload="true" wraps a response in a <textarea>. It is supposed to do that. And it helps to get it working in my test case.

    File upload

    You are right. Two things.
    First the requested method return type should be changed from DirectResponse to void ,and new DirectResponse shout include Return()
    like this 
       new DirectResponse
        {
            Script = msgBox.ToScript(),
            IsUpload = true
        }.Return();
