I have the following DataGridin WPF with two groups.
The first group is the bool flag, which represents whether the person is active / inactive.
The second group (or subgroup) is the identifier of each person. Each person can have several cities, therefore grouping for identifier, because each person is displayed several in DataGrid.
Here is the XAML:
<DataGrid CanUserAddRows="False" AutoGenerateColumns="False" ItemsSource="{Binding DataSource}">
<DataGrid.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Expander IsExpanded="True">
<Expander.Style>
<Style TargetType="{x:Type Expander}">
<Style.Triggers>
<DataTrigger Binding="{Binding Name}" Value="True">
<Setter Property="Background" Value="{StaticResource ActiveBrush}"/>
</DataTrigger>
<DataTrigger Binding="{Binding Name}" Value="False">
<Setter Property="Background" Value="{StaticResource InactiveBrush}"/>
<Setter Property="FontStyle" Value="Italic"/>
<Setter Property="Foreground" Value="Gray"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Expander.Style>
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name, Converter={StaticResource BoolToTextConverter}}" Margin="5 2 5 2"/>
<TextBlock Text=":" Margin="0 2 5 2"/>
<TextBlock Text="{Binding ItemCount}" Margin="0 2 0 2"/>
</StackPanel>
</Expander.Header>
<ItemsPresenter />
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Background="LightSteelBlue">
<TextBlock Text="{Binding Name}" Foreground="White" Margin="5 2 5 2"/>
</StackPanel>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</DataGrid.GroupStyle>
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<StackPanel>
<DockPanel>
<Button BorderThickness="0" Content="Edit" Margin="3"
Command="{Binding Commands.Edit}"
CommandParameter="{Binding SelectedItem, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}"/>
</DockPanel>
</StackPanel>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
<DataGridTextColumn Header="ID" Binding="{Binding ID}" IsReadOnly="True"/>
<DataGridTextColumn Header="Name" Binding="{Binding Name}" IsReadOnly="True"/>
<DataGridTextColumn Header="City" Binding="{Binding City}" IsReadOnly="True"/>
</DataGrid.Columns>
</DataGrid>
Everything works great ! However, I do not like the blue line for each subgroup. What I want to achieve is the grouping style in the following image:
, "" .
? XAML ?
Edit
:
public class Person
{
public Person(bool active, int id, string name, string city)
{
Active = active;
ID = id;
Name = name;
City = city;
}
public bool Active { get; set; }
public int ID { get; set; }
public string Name { get; set; }
public string City { get; set; }
}
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
DataContext = this;
var data = new ObservableCollection<Person>
{
new Person(true, 233, "Max", "New York"),
new Person(true, 233, "Max", "Los Angeles"),
new Person(true, 314, "John", "Paris"),
new Person(true, 578, "Mary", "Vienna"),
new Person(true, 782, "Susan", "Rome"),
new Person(true, 782, "Susan", "Prague"),
new Person(true, 782, "Susan", "San Francisco"),
new Person(false, 151, "Henry", "Chicago")
};
DataSource = new ListCollectionView(data);
}
private ListCollectionView _dataSource;
public ListCollectionView DataSource
{
get { return _dataSource; }
set
{
_dataSource = value;
_dataSource.GroupDescriptions.Add(new PropertyGroupDescription("Active"));
_dataSource.GroupDescriptions.Add(new PropertyGroupDescription("ID"));
}
}
