Hi Jose,
you could use the following Style to set the Background of a DataCell to Red when its Content value is equal to a double 1.0:
<Style TargetType="xcdg:DataCell">
<Style.Triggers>
<Trigger Property="Content">
<Trigger.Value>
<s:Double>1.0</s:Double>
</Trigger.Value>
<Setter Property="Background"
Value="Red" />
</Trigger>
</Style.Triggers>
</Style>
