ASP.NET AJAX Control Toolkit 11th Anniversary - v17.1.0 (Available Now)

ASP.NET Team Blog
12 April 2017

Today marks the ASP.NET AJAX Control Toolkit's 11 year anniversary! To celebrate, we're releasing v17.1.0 that contains new features, bug fixes, an updated installer, and NuGet packages. More on this below.

A long time ago...

Originally known as the “Atlas” Control Toolkit, this library was released on April 12th, 2006. If you'd like to go down memory lane, here's the official announcement that was followed by ScottGu's excellent blog post.

The first version of the AJAX Control Toolkit contained 35 UI controls. Later, a number of useful controls were added: charts, file upload controls, a color picker, and an HTML editor.

The toolkit has changed owners and gone through lots of source code changes. Check out this visualization of the AJAX Control Toolkit's source changes since 2009:

DevExpress Maintained & Upgraded

It's hard to believe but you can still upgrade the ASP.NET AJAX Control Toolkit from the very first release to the latest v17.1 without (major) issues. This is no small feat since it has changed source and evolved many times (see video). In fact, the ASP.NET AJAX Control Toolkit (DevExpress Edition) supports the latest versions of:

  • All major modern browsers (Chrome, IE, Firefox)
  • .NET Framework
  • Visual Studio IDE

v17.1 - Major Changes

ColorPickerExtender - new palette

A new continuous color palette was added to the ColorPickerExtender. Many thanks to Yoann Nivel for contributing this feature!

ASP.NET AJAX Control Toolkit - ColorPickerExtender

The new color palette is an optional property and can be enabled with the following code:

<ajaxToolkit:ColorPickerExtender PaletteStyle="Continuous" />

HtmlEditorExtender - Preview mode

Since the HtmlEditor has been deprecated, we've added the preview mode to it's replacement, the HtmlEditorExtender:

ASP.NET AJAX Control Toolkit - HtmlEditorExtender

This mode allows you to click on pasted links, which is not possible in content mode. To enable it, use this property:

<ajaxToolkit:HtmlEditorExtender DisplaySourceTab="true" />

AjaxFileUpload handler path - new property

A new property now allows you to specify the upload handler path programmatically for the AjaxFileUpload:

ajaxFileUpload.UploadHandlerPath = "MyFolder/AjaxFileUploadHandler.axd"
