FileSelect accepts more than one file through drag and drop.

[Twain]

Hello. 
I am using the FileSelect component to upload a single file. For this, I configured the property Multiple = false, and everything works as expected. The problem is that regardless of the Multiple state, more than one file can be uploaded through Drag and Drop. I believe this is an inconsistency in the component's logic since both file selection options should be limited. How can this be achieved in a simple way?

Another question: Is it possible to deactivate the drop zone?

Greetings. 
Twain.

Hello Twain,

Thank you for reporting this issue. It does indeed seem incorrect that when the user drops multiple files, the FileSelect selects all of them. Therefore, I have logged a Bug Report item on your behalf: https://feedback.telerik.com/blazor/1615763-the-restriction-of-selecting-only-one-file-when-multiple-false-is-bypassed-when-files-are-dragged

As a creator, you are automatically subscribed to receive email notifications about status changes. I have added your vote there to increase its popularity, as we prioritize fixes based on community demand and severity.

In the meantime, as a workaround, you can check the `args.Files` count in the OnSelect event and cancel the event if there are multiple files, preventing the selection of multiple files.

    async Task OnSelectHandler(FileSelectEventArgs args)
    {
        if(args.Files.Count() > 1)
        {
            args.IsCancelled = true;
            return;

        }

As a token of gratitude for helping us identify this issue, I have updated your Telerik points.

Regarding your question - currently, the API does not expose a configuration/parameter that allows you to deactivate the drop zone.
