Examples

The following example shows how to define a HeaderContainerStyle that specifies display properties for a column header.

<Style x:Key="myHeaderStyle" TargetType="{x:Type GridViewColumnHeader}">
  <Setter Property="Background" Value="LightBlue"/>
</Style>

<GridViewColumn Header="Month" Width="80"
      HeaderContainerStyle="{StaticResource myHeaderStyle}"
      HeaderTemplate="{StaticResource myHeaderTemplate}"
      DisplayMemberBinding="{Binding Path=Month}"/>

The following example shows how to define a HeaderContainerStyle that defines display properties by using a ControlTemplate.

<Style x:Key="myControlTemplateStyle" 
       TargetType="{x:Type GridViewColumnHeader}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type GridViewColumnHeader}">
        <Grid Background="LightBlue">
          <DockPanel HorizontalAlignment="Center"
                      VerticalAlignment="Center">
            <CheckBox></CheckBox>
            <TextBlock Text="{TemplateBinding Content}" 
                  FontSize="16" Foreground="DarkBlue"/>
          </DockPanel>
          <Canvas>
          <Thumb x:Name="PART_HeaderGripper"
                 Style="{StaticResource GridViewColumnHeaderGripper}"
                 Background="Transparent"
                 />
        </Canvas>
        </Grid>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

<GridView ColumnHeaderContainerStyle="{StaticResource 
                       myControlTemplateStyle}">
  <GridViewColumn Header="Year" Width="80"
        CellTemplate="{StaticResource myCellTemplateYear}"/>
  <GridViewColumn Header="Month" Width="80"
        CellTemplate="{StaticResource myCellTemplateMonth}"/>
  <GridViewColumn Header="Day" Width="80"
        CellTemplate="{StaticResource myCellTemplateDay}"/>
</GridView>

Remarks

The HeaderContainerStyle property and the HeaderTemplate property can together define property values and the visual tree for column header content. The HeaderContainerStyle property can also specify the visual tree by defining a ControlTemplate.

Properties that define the content, layout, and style of a column header are found in many related classes, and some of these properties have functionality that is similar or the same. For more information, see GridView Column Header Styles and Templates Overview.

When you set a style, some restrictions apply. For more information, see the Styling and Templating.
