Dragging onto the button effectively drags the file on the <input> element, which lets the browser capture the files immediately, without any additional application code (effectively, it acts the same way as using the OS selection window) and so the current code and functionality "just works™".
To extend this to other areas of the page, we need to write additional code to handle JS events there, and pass data along to the C# (Blazor) portion of the app. Thus, this feature needs to be implemented in the component and I am sorry to say that a workaround is not possible.
Hi, is there any workaround how to drop files into Blazor TelerikUpload? It works when I drop the file on the "Select files..." button. Could this behavior be extended somehow to a bigger area (dropzone)?
