Hi,

I've downgraded from Visual Web Dev 2008 to 2005 and things work a lot better.

Using the UploadManager sample program, I've added a textbox and a button on the main form.  I've set AutoUploadOnPostBack="False".  I've put SlickUpload_Submit(); in the OnClientClick property of the button and everything works fine.

However, what I'm trying to do is to validate the data in the textbox and depending on its value the button click will start the upload or not.  The button click event only gets triggered after the upload is completed.
Basically, all I need is to make sure the textbox has data before uploading.

Can this be done? If so how?

Thanks
