Ok, I finally figured out why this wasn't working.  In the custom properties where I supplied the data list, the Data value didn't have "Office2013".  I had to write in Office2013 then add the comboTool.Value = ToolbarStyle.Office2013 and now it works.

Thank you!

With the sample I wasn't able to get working.  I am testing your latest one now and it does fire the Event.  But it still doesn't force the word Offce2013 into the combobox display.  I will keep working this and let you know.

Based on your reply, I'm not sure if you managed to get this working or are trying to get a reference to the ComboBoxTool so you can set the Value property. If you are trying to get the root tool, you can use code similar to:

ComboxBoxTool comboTool = (ComboxBoxTool)this.ultraToolbarsManager1.Tools["comboBoxTool1"];

comboTool.Value = ToolbarStyle.Office2013;

Ok, since I do not programmatically create my combobox and my value list is already added, I do I to my specific comboBox which has a key of "comboBoxTool1" so then I can add "           // Assign the value to the root ComboBoxTool. This will trigger the ToolValueChanged event, and cause the Style of the UltraToolbarsManager to be set.
            comboboxtool.Value = ToolbarStyle.Office2013;" 

Ok, yes your example is what I want to do.  I'm going to try to see how to change my code to the "Office2013" to display.
