But in the application when I try to set the property I get the error: SelectedItem is read-only.

I am afraid that, currently, RadTreeMap doesn't support programmatic selection. The documentation of the SelectedItem property is incorrect. This will be updated. You can find the correct one in the API reference documentation of the RadTreeMapBase class.
