stop user until the file upload is completed.

Question

Hi,

 

I implement a code to upload a file through AJAXtoolkit Fileupload.

 

when a file is in uploading state user is pressing the save button, the file is not completly uploaing in the server folder and cause some session errors and page is collapsed.

 

i want to stop the user for some time until the file is completly uploaded in the server and the ajax fileupload will turns into green color then only we should allow th user to click save button. in this process i need to run a process wheel untill the file uploading is completed.

 

any ideas please..??
