How to set DataGrid's row Background, based on a property value using data bindings

Use a DataTrigger:

<DataGrid ItemsSource="{Binding YourItemsSource}">    <DataGrid.RowStyle>        <Style TargetType="DataGridRow">             <Style.Triggers>                <DataTrigger Binding="{Binding State}" Value="State1">                    <Setter Property="Background" Value="Red"></Setter>                </DataTrigger>                <DataTrigger Binding="{Binding State}" Value="State2">                    <Setter Property="Background" Value="Green"></Setter>                </DataTrigger>            </Style.Triggers>        </Style>    </DataGrid.RowStyle></DataGrid>

The same can be done without DataTrigger too:

 <DataGrid.RowStyle>     <Style TargetType="DataGridRow">         <Setter Property="Background" >             <Setter.Value>                 <Binding Path="State" Converter="{StaticResource BooleanToBrushConverter}">                     <Binding.ConverterParameter>                         <x:Array Type="SolidColorBrush">                             <SolidColorBrush Color="{StaticResource RedColor}"/>                             <SolidColorBrush Color="{StaticResource TransparentColor}"/>                         </x:Array>                     </Binding.ConverterParameter>                 </Binding>             </Setter.Value>         </Setter>     </Style> </DataGrid.RowStyle>

Where BooleanToBrushConverter is the following class:

public class BooleanToBrushConverter : IValueConverter{    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)    {        if (value == null)            return Brushes.Transparent;        Brush[] brushes = parameter as Brush[];        if (brushes == null)            return Brushes.Transparent;        bool isTrue;        bool.TryParse(value.ToString(), out isTrue);        if (isTrue)        {            var brush =  (SolidColorBrush)brushes[0];            return brush ?? Brushes.Transparent;        }        else        {            var brush = (SolidColorBrush)brushes[1];            return brush ?? Brushes.Transparent;        }    }    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)    {        throw new NotImplementedException();    }}

In XAML, add and define a RowStyle Property for the DataGrid with a goal to set the Background of the Row, to the Color defined in my Employee Object.

<DataGrid AutoGenerateColumns="False" ItemsSource="EmployeeList">   <DataGrid.RowStyle>        <Style TargetType="DataGridRow">             <Setter Property="Background" Value="{Binding ColorSet}"/>        </Style>   </DataGrid.RowStyle>

And in my Employee Class

public class Employee {    public int Id { get; set; }    public string Name { get; set; }    public int Age { get; set; }    public string ColorSet { get; set; }    public Employee() { }    public Employee(int id, string name, int age)    {        Id = id;        Name = name;        Age = age;        if (Age > 50)        {            ColorSet = "Green";        }        else if (Age > 100)        {            ColorSet = "Red";        }        else        {            ColorSet = "White";        }    }}

This way every Row of the DataGrid has the BackGround Color of the ColorSet Property of my Object.
