Hi,

 

for example:

 

function CuteWebUI_AjaxUploader_OnStart()
{

 //this function would be called on each file start upload

 //maybe be called many times when upload multiple files.
 document.forms[0].disabled=true;
}
function CuteWebUI_AjaxUploader_OnStop()
{

 //this function would be called if get error or user cancel it.
 document.forms[0].disabled=false;
}
function CuteWebUI_AjaxUploader_OnPostback()
{

 //this function would be called if upload progress done, before postback and server FileUploaded event.
 document.forms[0].disabled=false;
}

 

Regards,

Terry
