【问题描述】:
如果State 属于InProgress,并且所有其他选项都没有任何组,我如何进入GridView 为State 创建组?
public class RecordVm: VmBase
{
public int Id { get; set; }
public string Description { get; set; }
public State State { get; set; }
public bool IsCompeleted { get; set; }
}
public enum State
{
Empty, Opened, InProgress, Completed
}
public class MainVm : VmBase
{
public ObservableCollection<RecordVm> RecordVms { get; } = new ObservableCollection<RecordVm>();
public ListCollectionView ListCollection {get;}
public MainVm()
{
ListCollection = new ListCollectionView(RecordVms);
ListCollection.GroupDescriptions?.Add(new PropertyGroupDescription("State"));
}
}
目前,我为每个 State 变体创建了一个组,但这样的选项不适合我。
<DataGrid ItemsSource="{Binding ListCollection}"
Style="{StaticResource AzureDataGrid}"
RowStyle="{DynamicResource DataGridRowStyleStateGreen}">
<DataGrid.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Name}" />
</StackPanel>
</DataTemplate>
</GroupStyle.HeaderTemplate>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GroupItem}">
<Expander>
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=Name}" />
<TextBlock Margin="5,0,0,0" Text="{Binding Path=ItemCount}"/>
<TextBlock Text=" Items"/>
</StackPanel>
</Expander.Header>
<ItemsPresenter />
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</DataGrid.GroupStyle>
enter code here

最简单的方法可能是,您将另一个属性添加到您的模型并按该属性进行分组,而不是尝试跳过一些组
-
@lokusking,你做个小例子不难,我更能理解你的想法
