Property Value

Type: System.Windows.Style
The style that is used to render the column header; or null, to use the ColumnHeaderStyle setting. The registered default is null. For information about what can influence the value, see DependencyProperty.

To define a Style for a column header, specify a TargetType of DataGridColumnHeader.

A Style can be applied to all column headers or to an individual column header. To apply a Style to an individual header, set the DataGridColumn.HeaderStyle property, which takes precedence over the DataGrid.ColumnHeaderStyle property.

The following example uses a style resource to change the style of column headers in the DataGrid. The style of the first column header is then set with an inline style that overrides the DataGrid.ColumnHeaderStyle.

<Window.Resources>
    <!-- DataGrid style -->
    <Style x:Key="DataGridStyle1" TargetType="{x:Type DataGrid}">
        <Setter Property="ColumnHeaderStyle" Value="{DynamicResource ColumnHeaderStyle1}"/>
    </Style>
    <!-- DataGridColumnHeader style -->
    <Style x:Key="ColumnHeaderStyle1" TargetType="DataGridColumnHeader">
        <Setter Property="Height" Value="30"/>
        <Setter Property="Background" Value="LightBlue"/>
        <Setter Property="Foreground" Value="Blue"/>
        <Setter Property="FontSize" Value="18" />
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="ToolTip" Value="Click to sort."/>
            </Trigger>
        </Style.Triggers>
    </Style>
</Window.Resources>
<Grid>
    <DataGrid Name="dataGrid1" Margin="12,12,0,0" 
              AutoGenerateColumns="False"
              Style="{DynamicResource DataGridStyle1}">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Name" 
                                Binding="{Binding Name}">
                <!-- Local Style for header of first DataGrid column. -->
                <DataGridColumn.HeaderStyle>
                    <Style TargetType="DataGridColumnHeader">
                        <Setter Property="Background" Value="Blue"/>
                        <Setter Property="Foreground" Value="White"/>
                        <Setter Property="FontSize" Value="24"/>
                    </Style>
                </DataGridColumn.HeaderStyle>
