ASP.NET Team Blog
10 October 2018

Since taking over the ASP.NET AJAX Control Toolkit, we at DevExpress have been committed to keeping this library stable, modern, and useful. So I'm happy to announce the availability of v18.1.1 today.

This release brings several bug fixes and an enhancement. There is also a notable community contribution that will help those of you who are using an older version and want to upgrade to the latest release. Let's take a look.

Notable Community Contribution

From the DevExpress team that works on the toolkit, I'd like say thank you to developer tdjastrzebski. This dev has provided the ASP.NET AJAX Control Toolkit community with an updated AjaxControlToolkit.ScriptUserControl.

When we released the first version of the ASP.NET AJAX Control Toolkit (DevExpress edition) back in March 2015, we made several fixes and updates. One of those fixes involved removing the AjaxControlToolkit.ScriptUserControl because it was unused code and we could not validate how it worked properly. So the best decision, and correct one, was to remove it so that the release would be stable and we could provide other enhancements too.

Unfortunately, there was an issue for users who wanted upgrade their Toolkit install. Essentially, if you used the AjaxControlToolkit.ScriptUserControl then upgrading to v15.1+ meant that you would need to update your old code. There are some old ASP.NET Toolkit-based projects that still depend on this class.

Therefore, we're thankful that tdjastrzebski has developed the new version of the AjaxControlToolkit.ScriptUserControl that is compatible with the latest release of our ASP.NET AJAX Control Toolkit.

If you've been hesitant to upgrade to the latest version then please take a look at AjaxControlToolkit.ScriptUserControl and upgrade to the latest version of the ASP.NET AJAX Control Toolkit.
