hi

I need to add compulsory required field validation to file upload control . so that form should be submitted when the user has uploaded some file.

 

in simple words, if i have 4 fields in my form along wth the uploader component, while filling the form i want that user must select some file using upload button. else it should show up a message "Please select to file to upload".

 

 

thanks.

Hi,

Currently the Uploader can't not be applied the validation control.

 

while the uploader would do a postback to server after it upload a file,

 

You can send a flag to client side after the file are uploaded.

 

Or you can check our online sample :

 

(it should be included in the download package)

 

This example show how to start upload manually,

Its code also show you how to check whether the user have selected files.
