limit the number of files to upload

[Sean]

How can I limit the number of files to upload with the Kendo UI Upload widget?

Hello, Sean,

As the Upload does not have a built-in file number limitation, you can use the code below to achieve the requirement.

function select(e) {
    var files = e.sender.getFiles();
        if (files.length >= 5) {
            alert("Please select max 5 files.");
            e.preventDefault();
        }
}

Here is a small example for reference.

Let me know if you have any further questions.

What if the max = 3 files.  First time, user selects 2 files, but files are not auto uploaded...Then user selects 2 more files...How can I stop them and or just add 1 file so that it equals 3 before I upload them?  Thanks

Hello, Mark,

The code can be modified as in this Dojo example to prevent selecting more than 5 files. I am not sure if it would be possible to only select 1 in order to fit the max files allowed. A custom logic will also need to be added to reduce the variable that stores the number of the selected files when the user removes a file from the Upload list.
