Getting Started

Learn how to install the toolkit and add the toolkit to the Visual Studio/Visual Web Developer toolbox with the following videos and tutorials.

What's New?

This release of the Ajax Control Toolkit improves the performance of the Ajax Control Toolkit and makes it easier to create custom Ajax Control Toolkit controls.

For details on the new features included with this release, please see Stephen Walther's blog post at
  • Control Bundles - Use Control Bundles to specify the subset of the Ajax Control Toolkit controls that you want to use in your app. Control Bundles can substantially improve the performance of your app by enabling you to download only the scripts that you need.
  • CombineScripts Handler - Use the new AjaxControlToolkit.CombineScripts handler to cache Ajax Control Toolkit scripts for an entire app. To take advantage of the CombineScripts handler, you need to register the handler in your web.config file (see the sample website).

What's Changed?

  • Visual Studio 2012 Solution - Starting with this release, you must use Visual Studio 2012 when working with the Ajax Control Toolkit source code. We no longer maintain separate Visual Studio 2008, Visual Studio 2010, and Visual Studio 2012 solution and project files.
  • Sanitizer Providers - The Sanitizer Providers no longer ship in a separate assembly. The code has been merged into the AjaxControlToolkit.dll assembly. You will need to update your web.config file (see the sample website).

This release of the Ajax Control Toolkit was brought to you by Superexpert Consulting -- we build ASP.NET websites

Reviews for this release

Normally, I would rate the toolkit very highly. However, as of this July release, the toolkit is no longer FIPS compliant. This means it, and subsequent releases, can no longer be implemented on government servers that are secured to federal security guidelines. I submitted issue 27501. Please fix this issue!

The AjaxFileUpload control still throws a NotImplementedException when trying to make use of the ContextKeys property. Given the way this control operates, having context keys is pretty essential and it should never have been left out.

Huge issue We only use the most basic of features and getting errors.

Wow, did someone just forget to uncomment code? protected override IEnumerable<ScriptReference> GetScriptReferences() { if (!Visible) return null; List<ScriptReference> refs = new List<ScriptReference>(); //refs.AddRange(ScriptObjectBuilder.GetScriptReferences(GetType())); //if (ScriptPath.Length > 0) //{ //

AjaxControlToolkit.config: <controlBundles> <controlBundle> <control name="CalendarExtender" /> <control name="AjaxFileUpload" /> <control name="AsyncFileUpload" /> <control name="CascadingDropDown" /> </controlBundle> Still CascadingDropDown doesn't work. If I delete del config file, it works again.

This error was encountered after upgraded. Server Error in '/' Application. -------------------------------------------------------------------------------- Could not load control AjaxControlToolkit.HTMLEditor.Editor. The script reference(s) of this control was not loaded correctly. If AjaxControlToolkit.config is used, probably this control is not registered properly. Description: An unhan
