Hello David,

We already have two different file upload components:

• a file select type of component where you get the file data in an event raised by the component: https://demos.telerik.com/blazor-ui/fileselect/overview
• an async file upload that sends the file to an endpoint directly: https://demos.telerik.com/blazor-ui/upload/overview

With both of these you can drag a file over the "Select Files..." button to have it uploaded.

Once you have the file data (in either of the approaches) you can then use it in the blazor app - for example, add another component for an image preview, or anything else that your business logic requires. These parts, however, are not part of the upload component itself.

With that said, I am going to mark this one as a Completed request because we already provide the capability to do what you need to do. Perhaps the only thing that is still not yet here is the custom drop zone feature.

I would also suggest you browse through the currently open enhancement ideas for the upload component to get an idea of what currently exists in this idea stage so you can see of something from that is interesting to you.
