我是 wpf 的新手。我正在.net 3.5 中使用 wpf 开发一个小型应用程序。我有一个与数据表绑定的 wpf toolkid 数据网格控件。现在我无法在我的数据网格上对数据进行分组。
谁能告诉我如何做到这一点?
这是我的xmal
<Window.Resources>
<Style x:Key="GroupHeaderStyle" TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Expander x:Name="exp" IsExpanded="True"
Background="White"
Foreground="Black">
<Expander.Header>
<TextBlock Text="{Binding AdmissionDate}"/>
</Expander.Header>
<ItemsPresenter />
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>

这是我隐藏的代码
public partial class MainApp : Window
{
TestTakerDataSet takerDs = new TestTakerDataSet();
TestTakersTableAdapter takerTa = new TestTakersTableAdapter();
CollectionView view;
private void Window_Loaded(object sender, RoutedEventArgs e)
{
takerTa.FillByTerm(takerDs.TestTakers, "2010-2011T1E");
view = (CollectionView)CollectionViewSource.GetDefaultView(takerDs.TestTakers);
this.DataContext=view;
}
}
