Upload Complete Experience

Built-in file saving

Unlike standard ASP.NET file upload, WebFileUploader doesn’t require you to write codes to save uploaded files. Just set the UploadPath property of the WebFileUploader control and you’re all set.

WebFileUploader automatically saves all uploaded files to the specified upload path. Make sure you have configured sufficient security and permission settings for ASP.NET worker process to access the specified upload path.

You can enter physical path, IIS virtual path, or network path for the upload location. The default upload path is ~/Upload.

Memory-efficient, powerful uploading engine.

Webfarm and multiple worker requests support with built-in FileStateServer

Webfarm upload

Due to AJAX uploading mechanism, most file upload components will fail to work when the application is used in a webfarm environment, or in server running multiple worker requests.

When running in such configuration, the load balancer automatically redirects the AJAX request to one of the available servers which may not be the originating server that receives the upload data. This mechanism affects the file upload component since the AJAX request may receive invalid response and thus unable to obtain the required upload information which finally failing the progress bar.

Intersoft WebFileUploader addressed this limitation elegantly with FileStateServer technology. When using FileStateServer, WebFileUploader streamlines all required uploading information in its state server, making it possible for AJAX request to receive real-time synchronized information regardless of the server that process the request.

IIS integrated mode

WebFileUploader is built upon http module to provide reliable, memory-efficient implementation for large file uploads support. In addition, it also relies on http handler to support many advanced features such ability to abort currently uploaded files, cancel other pending uploads, and more.

Large file upload with minimal resources consumption

The standard ASP.NET file upload component often fails when uploading large files, for instance, a 10 MB file. Two of the most common errors are request time out and out of memory error. That happened because the standard file uploading implementation in ASP.NET requires the file to be entirely uploaded before it returns a response to the client side.

WebFileUploader takes advantage of HttpModule technology to handle large file upload with a more sophisticated implementation that doesn’t perform memory-level buffering. As the result, WebFileUploader can handle large file uploads with very minimal memory and resources consumption.

Automatic and batch upload.

With automatic upload feature, each selected file will be uploaded immediately without any additional efforts. This feature is suitable for data form that accepts only a single file upload. However, it could be useful in some other advanced scenarios as well, such as in mail application.

Batch upload mode

Batch upload is the default upload type in WebFileUploader. With batch upload, users can add multiple files in the uploader interface, and then upload all selected files in a single session.

Batch upload provides more intuitive and better controls on the uploading process – such as users can add several files, or remove unnecessary files or change the files – making it the preferred upload type for most file uploading scenarios.

Batch Upload mode

Batch upload with priority mode

When using batch upload type, you can also configure the upload priority which decides the logical order of the files to be uploaded.

You can set the upload priority by series, which is the default value, or by type. By series means the files will be uploaded in the original sequence as they were added in the uploader interface, while by type means files with same type will be uploaded first, then following the other types in alphabetical order

Batch Upload with Priority mode

Simultaneous batch upload mode

By default, WebFileUploader uploads one file at a time to avoid over consumption on bandwidth and resources. However, WebFileUploader can also be configured to upload multiple files asynchronously to support enterprise-level usage, such as internal or corporate web application.

Since WebFileUploader will upload all files simultaneously, please use this feature with caution as it will significantly affect your server’s workload and resources consumption. Make sure you have load-tested your server properly to use this feature. It’s also advisable to use this feature with file validation for enhanced security.

Simultaneous batch upload mode

Built-in file validation.

WebFileUploader gives you the flexibility to set the number of initial file upload fields that displayed in panel user interface. This property is not applicable for attachment bar user interface.

Limit upload files based on type, count, or custom

Real-time progress bar

WebFileUploader easily lets you enhanced your application’s security by limiting the upload files based on type, count, or custom rules.

By default, WebFileUploader automatically validates redundant files. That means you can't select the same file that already been added.

To limit file types, set the FileTypes property to the file extensions with mask. You can enter multiple file types by separating each type with a semicolon separator, such as *.png;*.gif;*.jpg. To limit files count, simply set the FilesCount to an integer number.

Limit upload size and total upload size

Limit upload size and total upload size

WebFileUploader is designed for enterprise file uploading usage which takes full account on security aspect. The most basic validation provided is limiting the upload size of an individual. By default, WebFileUploader doesn't limit the upload size.

In addition, WebFileUploader also enables you to limit the total size of all uploaded files. When it reach the maximum size, it will abort the current file being uploaded and cancel the rest pending uploads.

Easily customizable in client and server-side.

Customizable styles and appearances

WebFileUploader lets you create your own custom style easily via properties to match your overall application’s look-and-feel.

Localizable text element

WebFileUploader also provides localizable text element. This is important when you’re building a cross-culture application which requires sophisticated uploading experience.

Complete client-side events

WebFileUploader is designed with rock-solid API and extensible client-side events to give you total control over uploading process. Works in conjunction with real-time progress bar feature, WebFileUploader sent event notification to client-side in real-time – such as OnBeforeUpload, OnAfterUpload OnErrorUpload, and even OnUploading event.

Complete server-side events

In addition to client-side events, WebFileUploader also provides comprehensive server-side events, making it easy for developers to customize and extend the control with additional processing on certain event.

It is designed with sophisticated architecture that enables server-side events to be raised properly, although WebFileUploader doesn’t have direct access to the Page object due to the nature of its architecture that used more advanced HttpModule/HttpHandler technology instead of old-fashioned AJAX.
