ComboBox项目源
原标题:binding ComboBox item source

缩略语 (它有<代码>ItemSource)我的行文有<条码>ComboBox,并谨将其<条码>与<条码>所载名单挂钩,但可加附。 由于不是ViewModel,任何人都有解决这一问题的想法?

样本:

<代码>CilyCollection和StatusListViewModel上的两份清单。 每个城市都有<代码>Status财产。

<Grid x:Name="LayoutRoot" DataContext="ViewModel">
    <sdk:DataGrid Grid.Row="1"
                  AutoGenerateColumns="False"
                  ItemsSource="{Binding CityCollection}">
        <Controls:DataGrid.Columns>
            <Controls:DataGridTemplateColumn Header="Status">
                <Controls:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <ComboBox ItemsSource="{Binding StatusList}"
                                  Margin="2"
                                  SelectedItem="{Binding status,Mode=TwoWay}"
                                  ItemTemplate="{StaticResource StatusTemplate}" />
                    </DataTemplate>
                </Controls:DataGridTemplateColumn.CellTemplate>
            </Controls:DataGridTemplateColumn>
        </Controls:DataGrid.Columns>
    </sdk:DataGrid>
</Grid>

2. 具有相对约束源的物品

{Binding DataContext.StatusList, RelativeSource={RelativeSource  AncestorType={x:Type ItemsControl}}}

您可在数据表中查阅CilyCollection项目。 因此,你可以控制城市的地位财产。 身份识别员无法使用。 对地位党进行约束:

< DataTemplate >

< ComboBox itemsSource= ElementName=LayoutRoot, Path=DataContext.StatusList}>

......
