Hello,

I will be happy to assist you with this question.

I am not 100% sure if I understand your question, however, I believe that you would like to utilize the KeyTip property within the ultraToolbarsManager control. To do this, I recommend using the following code for for first instance of the first tool in a Ribbon:

this.ultraToolbarsManager.Ribbon.Tabs[0].Group[0].Tolls[0].SharedProps.KeyTip = "123";

Please use the following page in the Infragistics documentation to learn more about the SharedProps property:

Please let me know if you have further questions regarding this matter.
