Upload

ASP.NET Core File Upload

Let your users upload single or multiple files with item selection or drag and drop. Use Upload widget to upload on a postback or the AsyncUpload to do it via AJAX. Events triggered by the HTML5 kendoUpload are easily handled via a console log. Lastly, leverage the built-in file size and extension validation.

Tag Helper

The Upload Tag Helper gives a rich HTML-like syntax to create an upload area to any ASP.NET Core application.
Asynchronous Upload

The Core File Upload control can be used as a themeable and customizable replacement for file input elements. This means users can upload files to your server asynchronously. Also, multiple files can be selected and uploaded on their own, without the need to wait for each to be uploaded completely.

See demo
Synchronous Upload

If the asynchronous approach doesn’t fit your application, don’t worry. Our Core Upload component can upload all files using the more traditional synchronous approach as well.

Visual Indicators for Common Operations

Make use of the rich UI showing visual notifications for common operations: successful upload, failed validation and upload in progress. Complement that with our useful cancel upload button.

Drag and Drop File Upload

Leverage the latest technology trends with Telerik File Upload in ASP.NET Core and enable your end users to upload files using drag and drop functionality. They can drop the desired files over the upload, or define custom drop zones over the page—and all of this is achieved codelessly.

Server- and Client-Side API for Max Flexibility

UI for ASP.NET Core comes with a complete server-side API. With simple API calls designed to feel natural in server-side languages, you can configure all features of the Core File Upload component. Since the server wrappers output the JavaScript, you also have full access to the client-side API for maximum control in the browser.
