Hi Bryan,
To disable the ability to resize the rows, you need to set the MinHeight and MaxHeight properties on the DataRow and make them the same value.
For example:
<Style TargetType="{x:Type xcdg:DataRow}" >
<Setter Property="MinHeight" Value="50" />
<Setter Property="MaxHeight" Value="50" />
</Style>
