WPF4 DataGridHeaderBorder in a xaml Style

2020-02-02 01:23发布

Making a separate question, related to comments on the answer to WPF 4: What happened to DataGridColumnHeader?

It appears I can use DataGridHeaderBorder in a UserControl, stand-alone in a ResourceDictionary, but not in a Style's setter of a Template.

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    >

    <!-- Works -->
    <DataTemplate x:Key="yomama">
        <DataGridColumnHeader />
    </DataTemplate>

    <!-- Compile Error: error MC3074: The tag 'DataGridHeaderBorder' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'. -->
    <Style x:Key="{x:Type DataGridRowHeader}"
        TargetType="{x:Type DataGridRowHeader}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type DataGridRowHeader}">
                    <Grid>
                        <DataGridHeaderBorder></DataGridHeaderBorder>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

I can get it to work if I use xmlns:dg="http://schemas.microsoft.com/wpf/2008/toolkit", even though I'm not referencing WPFToolkit in the project. I've verified I'm set to .NET4 and referencing PresentationFramework v4.

Thanks for helping me remove the dg: hack.

You can also try this.In this case to change the foreground of the header.

<Style x:Key="Consulta_Grilla_HeaderStyle" 
       TargetType="{x:Type DataGridColumnHeader}">
    <Style.Resources>
        <Style TargetType="{x:Type Grid}" >
            <Setter Property="TextBlock.Foreground" Value="Yellow"/>      
        </Style>
    </Style.Resources>
</Style>
