    Upload Grid Displaying Uploaded File Disappears when Server Trace appears

    I am using the single file upload and note that after the file is upload, the gride with the file name and check mark appear for only a second, then immediately replaced by the Trace information.  I can not figure out what is caused the grid to disappear.  

     

    Also, I would like to customize the grid to remove the "delete" and replace it with a link to open the file that was just uploaded.

    Can you help?

    Re: Upload Grid Displaying Uploaded File Disappears when Server Trace appears

    Hi cjchamber,

     

    What you are using is "CuteWebUI:Uploader", it has not the attachment table. If you want to show the attachment table after upload, please use "CuteWebUI:UploadAttachments".

     

    And you can refer to http://www.ajaxuploader.com/Demo/Ajax-based-File-storage.aspx, it shows you how to create your own custom attachment table.

     

    Regards,

     

    Ken

    Re: Upload Grid Displaying Uploaded File Disappears when Server Trace appears

    Thanks Ken.  I'll look into it.  I was just curious because the grid (single upload / one row) actually flashes for a second then disappears.  (You can see it in the video).  Any reason why?

    hi cjchamber,

     

    It is the correct behavior. What you saw is the queue table, it only appears when uploading. So after uploaded, it will disappear. This is why I let you use "CuteWebUI:UploadAttachments".

     

    Regards,
