The Blazor File Upload is a component for uploading one or multiple files, images, documents, and audio and video files to a server. The File Upload works in both WebAssembly and Server-side Blazor apps, and also supports a rich set of features that include multiple file selection, progress bars, auto-uploading, drag and drop, folder (directory) uploading, file validation, and more.
Manage large file uploads efficiently without any performance degradation using chunk upload. The large files are sliced into small chunks and upload to the server in sequential order for asynchronous mode
A built-in feature is available to pause, resume, retry, and cancel a file upload. This helps users upload high-resolution images, videos,and other large files safely. Additionally, it provides an option to pause and resume automatically based on server connection.
Users can select multiple files and upload them to a server at the same time, which is useful for uploading images to a gallery and file sharing applications.
The Blazor file upload component can upload multiple files by simply dragging them from the file explorer to the drop area (drop zone), which is a more user-friendly way to select and upload multiple files.
The action buttons of the Blazor file upload component are completely customizable, including its file list, which helps you create your own design for the Blazor file upload UI.
Users can upload various file types and impose restrictions to allow only valid types of files from the client-side, which is mandatory before uploading a file in the web application.
Users can add validation to check file size limits with minimum and maximum ranges, number of files required, total size, and MIME type before uploading a file to a server.
The component accepts a folder (directory) as a file source for uploading. It uploads all the files (includes subfolders) of the selected folder.
The Blazor file upload component processes images from the clipboard, also. Simply copy and paste the images to be uploaded to a server.
The Blazor file upload component provides a simple interface to delete files from a server after uploading them, which helps you delete wrongly uploaded files.
Users can configure previously uploaded files from the server with a success state, which is useful for viewing, removing, and manipulating them.
Users can initiate an automatic upload to upload files immediately upon adding them to the upload queue.
Users can set corresponding translation texts to the static strings used in the Blazor file upload component through the localization library.
The Blazor file upload component supports right-to-left rendering, which improves the user experience and accessibility for those who use RTL languages.
The Blazor file uploader component has form support (synchronous mode) to work with native HTML forms.
Fully supports WAI-ARIA accessibility, which allows the Blazor file upload component to be accessed by on-screen readers and assistive devices.
Follows the WAI-ARIA Best Practices for implementing keyboard interaction.
The UI element visuals, such as foreground color, background color, line spacing, text, and images, were designed based on the WCAG 2.0 standard.
The Blazor file upload component provides the best user experience across phone, tablet, and desktop form factors.
The Blazor file uploader component has several built-in themes such as material, bootstrap, fabric (Office 365), and high contrast. Users can customize any one of these built-in themes or create new themes to achieve their own desired look and feel either by simply overriding SASS variables or using our Theme Studio application.
Developers can control the appearance and behaviors of the Blazor file upload, including its file list, using a rich set of APIs.
Easily get started with Blazor File Upload using a few simple lines of C# code, as demonstrated below. Also explore our Blazor File Upload Example that shows you how to render the uploader component.
<SfUploader AutoUpload="false">
<UploaderEvents ValueChange="OnChange"></UploaderEvents>
</SfUploader>
@code {
private void OnChange(UploadChangeEventArgs args)
{
foreach (var file in args.Files)
{
var path = @"path" + file.FileInfo.Name;
FileStream filestream = new FileStream(path, FileMode.Create, FileAccess.Write);
file.Stream.WriteTo(filestream);
filestream.Close();
file.Stream.Close();
}
}
}File Upload is also available in JavaScript, Angular, React and Vue frameworks that are built from their own TypeScript libraries. Check out the different File Upload platforms from the links below,
We do not sell the Blazor File Upload separately. It is only available for purchase as part of the Syncfusion Blazor suite, which contains over 65 native Blazor components, including the File Upload. A single developer license for the Syncfusion Essential Studio for Blazor suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
You can find our Blazor File Upload demo here.
No, our 65 Blazor components, including File Upload, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their File Upload alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 65 Blazor components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.
A good place to start would be our comprehensive getting started documentation.
