    Show Progress label when saving to database

    Reply Quote
    Hi,
     
    I have successfully created a upload session, and after upload, the FileUploaded is trigged.
    In this I save the file to a database, and I have portioned this up in smaller units, using column.write to a varbinary(max) column, since the upload will deal with files several hundred MB large. The problem is that it will take several seconds to do these savetoDB calls. So how can I within my FileUploaded procedure use a control to show the progress. Let's say as a simple label:
    for(int step; step<=steps;step++)
    {
       Label1.text = "Saving uploaded file to database step "+step+" of "+steps;
       ... ...
    }
    I have no problem with the portioning nor the sql calls, but I can't manage to refresh a label within the FileUploaded procedure.
     
    Thanks in advance for your help
    /Magnus

    Hi Kenneth,
     
    I think he meant a progress update for his own server-side events, not client side Uploader-events.
    Like when he is saving the file to a database, so that the user doesn't get bored or confused.
     
    Bye

    Hi,
     
    Currently we have no good ideas to let client show the server side progress directly.
     
    Now you can do this thing :
     
    1 , on the server FileValidating event, start a new thread to copy the filedata to database, and return the request directly.
    2 , on the client side, you can use the OnTaskComplete event, and start a new function to check the server side status.
     
    We will consider a buildin API for that cool feature.
     
    Regards,
    Terry
