How to create the diagonal line with header in WPF DataGrid?

In WPF DataGrid (SfDataGrid), a diagonal line can be added to a column header by using the HeaderTemplate property. This can be achieved by creating a custom DataTemplate and assigning it to the HeaderTemplate.

<syncfusion:GridTextColumn HeaderText="Order ID" 
                           MappingName="OrderID">
    <syncfusion:GridTextColumn.HeaderTemplate>
        <DataTemplate>
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <TextBlock Grid.Row="0" 
                           Text="Value1" 
                           HorizontalAlignment="Center"
                           VerticalAlignment="Center"/>
                <TextBlock Grid.Row="1" 
                           Text="Value2" 
                           HorizontalAlignment="Center"
                           VerticalAlignment="Center"/>
                <Line Grid.RowSpan="2" X1="150" Y1="0" X2="0" Y2="90" 
                      Stroke="Black"  
                      StrokeThickness="2"/>
            </Grid>
        </DataTemplate>
    </syncfusion:GridTextColumn.HeaderTemplate>
</syncfusion:GridTextColumn>
