Usually for validation, it involves allowed file types but just want to ask how to validate file size only? Thanks.

I also noticed when setting the error message, first it's like checking if message is about file type then else it becomes error regarding file size as show below:

function getErrorMessage(sender, args) {
        var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);
        if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct
            if (sender.get_allowedFileExtensions().indexOf(fileExtention) == -1) {
                return ("This file type is not supported.");
            }
            else {
                return ("This file exceeds the maximum allowed size of 500 KB.");
            }
        }
        else {
            return ("not correct extension.");
        }
    }

Hello Jayzle,

Yes, you can validate only the file size limit. Actually, if we assume that you don't have set the file types and extensions - the event will be triggered only if the max file size is exceed. In other words, you can directly display the message for the exceeded size, if the OnClientValiaditionFailed client-side event is triggered.

However, if you have defined the AllowedFileExtensions and MaxFileSize, you should use the demonstrated code-snippet, in order to differentiate which is the exact error thrown, as the OnClientValidationFaild suites for both errors.

Hi Nencho,

 Yes, that's what I did as shown below. Thank you for your response.

function OnValidationFailed(sender, args) {
            var $row = $(args.get_row());
            var erorMessage = "File exceeds maximum allowed size of 5MB and will not be uploaded.";
            var span = createError(erorMessage);
            $row.addClass("ruError");
            $row.append(span);                                
             
        }
