我有一个已创建的自定义选项卡控件,但我遇到了问题。我有一个可编辑的文本框作为自定义 TabControl 视图的一部分。
<Controls:EditableTextControl x:Name="PageTypeName"
Style="{StaticResource ResourceKey={x:Type Controls:EditableTextControl}}" Grid.Row="0" TabIndex="0"
Uid="0"
AutomationProperties.AutomationId="PageTypeNameTextBox"
AutomationProperties.Name="PageTypeName"
Visibility="{Binding ElementName=PageTabControl,Path=ShowPageType}">
<Controls:EditableTextControl.ContextMenu>
<ContextMenu x:Name="TabContextMenu">
<MenuItem Header="Rename Page Type" Command="{Binding Path=PlacementTarget.EnterEditMode, RelativeSource={RelativeSource AncestorType=ContextMenu}}"
AutomationProperties.AutomationId="RenamePageTypeMenuItem"
AutomationProperties.Name="RenamePageType"/>
<MenuItem Header="Delete Page Type" Command="{Binding Path=PageTypeDeletedCommand}"
AutomationProperties.AutomationId="DeletePageTypeMenuItem"
AutomationProperties.Name="DeletePageType"/>
</ContextMenu>
</Controls:EditableTextControl.ContextMenu>
<Controls:EditableTextControl.Content>
<!--<Binding Path="CurrentPageTypeViewModel.Name" Mode="TwoWay"/>-->
<Binding ElementName="PageTabControl" Path="CurrentPageTypeName" Mode ="TwoWay"/>
</Controls:EditableTextControl.Content>
</Controls:EditableTextControl>
在内容部分,我绑定到一个名为 CurrentPageTypeName 的 Dependency Prop。这个 Dependency 属性是这个自定义选项卡控件的一部分。
public static DependencyProperty CurrentPageTypeNameProperty = DependencyProperty.Register("CurrentPageTypeName", typeof(object), typeof(TabControlView));
public object CurrentPageTypeName
{
get { return GetValue(CurrentPageTypeNameProperty) as object; }
set { SetValue(CurrentPageTypeNameProperty, value); }
}
在另一个视图中,我使用自定义 TabControl 然后将我的属性与实际名称值绑定到 CurrentPageTypeName 属性,如下所示:
<Views:TabControlView Grid.Row="0" Name="RunPageTabControl"
TabItemsSource="{Binding RunPageTypeViewModels}"
SelectedTab="{Binding Converter={StaticResource debugConverter}}"
CurrentPageTypeName="{Binding Path=RunPageName, Mode=TwoWay}"
TabContentTemplateSelector="{StaticResource tabItemTemplateSelector}"
SelectedIndex="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.SelectedTabIndex}"
ShowPageType="Hidden" >
<!--<Views:TabControlView.TabContentTemplate>
<DataTemplate DataType="{x:Type ViewModels:RunPageTypeViewModel}">
<RunViews:RunPageTypeView/>
</DataTemplate>
</Views:TabControlView.TabContentTemplate>-->
</Views:TabControlView>
我的问题是似乎什么都没有发生。它是从 Itemsource 中获取其内容,而不是从我的链式 Dependency 道具中获取。我正在尝试的甚至可能吗?如果是这样,我做错了什么。
感谢您的关注。
