带有超链接的列表框 ->选择已更改
我想用 xaml 绑定实现这样的功能:
列表框包含超链接。
单击超链接时 - 我们转到另一个框架
,但 SelectedItem 也必须更改,并且在另一个框架上我们显示有关所选项目的信息。
我想要它而不订阅点击/选定事件。 我的列表框的唯一声明性
示例
<ListBox Grid.Row="1"
x:Name="OrderTypesListBox"
ItemsSource="{Binding OrderTypes, Mode=OneWay}"
SelectedItem="{Binding SelectedCall.OrderType, Mode=TwoWay}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Name}" />
<HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/WindowPage" TargetName="ContentFrame" Content="WindowPage"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
现在像这样解决
<ListBox Grid.Row="1"
x:Name="OrderTypesListBox"
ItemsSource="{Binding OrderTypes, Mode=OneWay}"
SelectedItem="{Binding SelectedCall.OrderType, Mode=TwoWay}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<HyperlinkButton
TargetName="ContentFrame"
NavigateUri="{Binding OrderTypeNextPage}"
Content="{Binding Name}"
Click="HyperlinkButton_Click"
Tag="{Binding}"
/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
private void HyperlinkButton_Click(object sender, RoutedEventArgs e)
{
OrderTypesListBox.SelectedItem = (sender as HyperlinkButton).Tag;
}
I want to do with xaml bindings such feature:
Listbox contains hyperlinks.
When hyperlink clicked - we go to another frame
But also SelectedItem must changed, and on another frame we show info about selected item.
I want it without subscribing click/selected events. Only declarative
Example of my listbox
<ListBox Grid.Row="1"
x:Name="OrderTypesListBox"
ItemsSource="{Binding OrderTypes, Mode=OneWay}"
SelectedItem="{Binding SelectedCall.OrderType, Mode=TwoWay}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Name}" />
<HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/WindowPage" TargetName="ContentFrame" Content="WindowPage"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Now solve like that
<ListBox Grid.Row="1"
x:Name="OrderTypesListBox"
ItemsSource="{Binding OrderTypes, Mode=OneWay}"
SelectedItem="{Binding SelectedCall.OrderType, Mode=TwoWay}"
>
<ListBox.ItemTemplate>
<DataTemplate>
<HyperlinkButton
TargetName="ContentFrame"
NavigateUri="{Binding OrderTypeNextPage}"
Content="{Binding Name}"
Click="HyperlinkButton_Click"
Tag="{Binding}"
/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
private void HyperlinkButton_Click(object sender, RoutedEventArgs e)
{
OrderTypesListBox.SelectedItem = (sender as HyperlinkButton).Tag;
}

不要使用超链接按钮。当 ViewModel 中的 SelectedItem 发生更改时,执行所需的操作。
编辑:如果您需要响应所有点击事件,即使该项目已被选中,那么您可以使用行为来执行此操作。只需为 TextBlock 创建一个在 TextBlock 单击事件上导航的行为即可。
Edit2: 行为的编码非常简单且易于使用(并且不会破坏 MVVM 范式)。
Don't use a HyperlinkButton. Perform the needed actions when the SelectedItem changes in your ViewModel.
Edit: If you need to respond to all click events even if the item is already selected then you can use a Behavior to do this. Just create a behavior for the TextBlock that navigates on the TextBlock click event.
Edit2: Behaviors are pretty simple to code up and easy to use (and don't break the MVVM paradigm).
