I was able to change the font-family and font size drop down lists, see example below using VB.NET.
<FTB:FreeTextBox runat="server" ID="ftb" />
Dim fontFaces() As String = {"Time New Roman", "Georgia", "Arial", "Tahoma", "Wingdings"} Dim fontFaceNames() As String = {"Time", "Georgia", "Arial", "Tahoma", "Wingdings"} ftb.FontFacesMenuList = fontFaces ftb.FontFacesMenuNames = fontFaceNames
Note: The list of font sizes available are 1-7, the default is 3.
Dim fontSizes() As String = {"1", "2", "3", "4", "5", "6", "7"} Dim fontSizeNames() As String = {"8", "10", "12", "14", "16", "18", "20"} ftb.FontSizesMenuList = fontSizes ftb.FontSizesMenuNames = fontSizeNames
