Hello Miguel,

Thank you for contacting Infragistics. Please clarify the specific component you are working with. (eg. XamTreeGrid or XamDataTree)

In which way do you want to modify our components?

Firstly, I'd like to point you to our themes topic in our online documentation where you can find details about customizing the look and feel.

Alternately, if you are already using the cross platform Data Tree, you can use the Infragistics XamTreeGrid.

Let me know if you have any questions.

Sincerely,
