我在WPF中使用了ItemsControl,将字典集合作为ItemsControl的ItemsSource。在这个字典集合中,使用了键和ObservableCollection。每个字典项的ObservableCollection中有不同的项目,所以当我提供一个ItemsSource时,它们将具有相同的高度。
代码如下:
<ItemsControl
Grid.Row="1"
Height="Auto"
ItemsSource="{Binding Values}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel
HorizontalAlignment="Stretch"
VerticalAlignment="Top"
IsItemsHost="True"
Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<GroupBox
MinWidth="303"
Margin="5,0,0,0">
<ItemsControl Margin="20,5,0,5">
<ItemsControl.Resources>
<CollectionViewSource x:Key="Collection" Source="{Binding Value}" />
<DataTemplate DataType="{x:Type Model:Sensor}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Label
Grid.Column="1"
Content="{Binding Name}"
FontFamily="SegoeUI-Semibold"
FontSize="12"
FontWeight="SemiBold" />
<Label
Grid.Column="2"
HorizontalContentAlignment="Center"
Content="{Binding Value}"
FontFamily="SegoeUI"
FontSize="12" />
</Grid>
</DataTemplate>
<DataTemplate DataType="{x:Type Model:DigitalInput}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Label
Grid.Column="1"
Content="{Binding Name}"
FontFamily="SegoeUI-Semibold"
FontSize="12"
FontWeight="SemiBold" />
<Label
Grid.Column="2"
HorizontalContentAlignment="Center"
Content="{Binding InputState}"
FontFamily="SegoeUI"
FontSize="12" />
</Grid>
</DataTemplate>
</ItemsControl.Resources>
<ItemsControl.ItemsSource>
<CompositeCollection>
<CollectionContainer Collection="{Binding Source={StaticResource Collection}}" />
</CompositeCollection>
</ItemsControl.ItemsSource>
</ItemsControl>
</GroupBox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
请查看类代码:
private Dictionary<string, ObservableCollection<IValue>> values;
public Dictionary<string, ObservableCollection<IValue>> Values
{
get { return values; }
set { values = value; }
}
