Upgrade your project to AjaxControlToolkit v15.1

Important note: The ASP.NET AJAX Control Toolkit v15.1 now requires that your project is using .NET framework v4.0 or higher. Projects targeting .NET framework v3.5 have to be migrated to a more recent .NET version before upgrading.

0 - Remove previous version

Make sure your have removed previous versions before installing ASP.NET AJAX Control Toolkit v15.1:
  1. If you have added the toolkit to Toolbox via the “Choose items...” dialog, remove an assembly reference and reset your toolbox.
  2. If you have added the toolkit via the NuGet package manager, simply uninstall the package from the solution.

1 - Install

To install the ASP.NET AJAX Control Toolkit v15.1 go to the Download page and get the new Installer (created by DevExpress).

If you use the fully-qualified name for the ASP.NET AJAX Control Toolkit assembly, then please ensure that all occurrences are updated (this includes references in web.config and @Register directives in the ASPX markup).

2 - Replace ToolkitScriptManager with ScriptManager

The ToolkitScriptManager has been deprecated for the v15.1 release. Please use the standard ScriptManager control. It should be sufficient to change the tag name in the markup from <yourTagPrefix>:ToolkitScriptManager -> asp:ScriptManager. If you find any issues, then please report them here.

Refer to the "ToolkitScriptManager Removed in v15.1, Use ScriptManager" article for details.

3 - Clean up Web.config

Remove the following outdated elements from your project’s web.config file:

// (in system.web/httpHandlers and system.webServer/handlers sections).
<add name="CombineScriptsHandler" verb="*" path="CombineScriptsHandler.axd" type="AjaxControlToolkit.CombineScriptsHandler, AjaxControlToolkit"/>

// (in system.web section)
<section name="sanitizer" requirePermission="false" type="AjaxControlToolkit.Sanitizer.ProviderSanitizerSection, AjaxControlToolkit"/> 

// (in system.web section)
<sanitizer defaultProvider="HtmlAgilityPackSanitizerProvider">
. . .

4 - Use Microsoft.Web.Optimization for bundling and minification

The AjaxControlToolkit.CombineScriptsHandler have been removed for v15.1 and resource bundling was delegated to the ASP.NET Web Optimization Framework.

Find the detailed description and instructions on enabling it in the following article: How to use bundling and CDN.

Note: if you use named Control Bundles (defined in the ~/AjaxControlToolkit.config file), then adjust the script bundle virtual path as shown below:


5 - Html Editor

The following namespaces have been renamed so please update your code accordingly:

Change AjaxControlToolkit.HTMLEditor to AjaxControlToolkit.HtmlEditor.
Change AjaxControlToolkit.HTMLEditor.ToolbarButton to AjaxControlToolkit.HtmlEditor.ToolbarButtons.

To reduce the number of dependencies, we have moved Html Sanitizer out to an external NuGet package: AjaxControlToolkit.HtmlEditor.Sanitizer

For security concerns, we recommend that you always use Html Editor together with Html Sanitizer.
