Hi Henrik,

Thank you for posting in our forums.

The easiest approach here would be to use the EventManager of the UltraToolbarsManager in order to disable the ToolClick event while changing the value. You can do this with the help of the SetEnabled method:

            try

            {

                ultraToolbarsManager1.EventManager.SetEnabled(ToolbarEventIds.ToolClick, false);

                stateButton.Checked = true;

            }

            finally

            {

                ultraToolbarsManager1.EventManager.SetEnabled(ToolbarEventIds.ToolClick, true);

            }
Please let me know if you have any additional questions.
