RadMessageBox has title and message ui elements inside it which have specific fonts sizes set. If you need to modify the fonts or the font sizes you can create a new control template for the RadMessageBoxControl class.
In order to avoid writing it from scratch you can copy the default RadMessageBoxControl style and modify its control template.
You can do this by extracting the style from the Telerik.Windows.Controls.Primitives.dll assembly with the reflector tool. The themes are located in a Resources folder inside the assembly.
You can also use the control template from this help article.
The special namespace looks like this:
xmlns:special="clr-namespace:Telerik.Windows.Controls.MessageBox;assembly=Telerik.Windows.Controls.Primitives"
Write again if have other questions. Regards,

please attach sample code that all of ui item in radmessagebox font be "Tahoma"
Here is where you can download the .net reflector tool. Once you have it installed, double click on the primitives assembly and it should open in reflector. If it does not open, right-click on the assembly and choose Open With from the windows menu and choose reflector (you may have to browse for the executable). After the assembly is open, look at the tree view on the left, select the primitives assembly and drill down to the resources folder. All themes are in the Telerik.Windows.Controls.Primitives.g.resources file. You are looking for the themes/messagebox.xaml file.
