The 15.1 AjaxControlToolkit release causes an error when Telerik UI for ASP.NET AJAX controls are used together with AjaxControlToolkit controls: "this._setProperties is undefined".
This issue appears when using controls like RadDateTimePicker and other controls.
After upgrading to AJAXControlToolkit v15.1 we have to downgrade again to work with telerik.
