How to check radupload control is blank on click of Submit button with Client-Side Validation.
i have already checked validated extension on client side with custom validator control.
i want to check radupload control cannot blank with this function.
I hope the following documentation is well suite to your scenario which checks for empty string and invalid extension. Go through the following link. Require at least one file to be uploaded
i want to check radupload control cannot blank and only allowed extension file will can upload with Server Side Validation .
if invalid extension file upload and RadUpload control is blank,radalert should come with Message from Server Side.
