다른 스택 패널의 스택 패널 너비를 만드는 방법은 무엇입니까?

Question

나는 각각 왼쪽 스택 패널이있는 두 개의 도크 패널이 있습니다.

의 너비 맨 아래 StackPanel은 폭의 너비에 의해 결정됩니다 텍스트 그 안에 있습니다.

의 너비 맨 위 StackPanel은 같은 너비로 맨 아래 스택 패널.

elementName을 통해 상단 스택 패널의 너비를 하단 스택 패널의 너비에 바인딩하려고했지만 작동하지 않습니다.

상단 너비를 하단 너비와 동일하게 만드는 방법은 무엇입니까?

<StackPanel>
    <DockPanel LastChildFill="True" Height="100" >
        <StackPanel Width="{Binding ElementName=LeftMenuText, Path=Width}" 
                    DockPanel.Dock="Left"
                    Background="Yellow">
            <TextBlock
                Text="This is some text."/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Right"
                    Background="Orange">
        </StackPanel>
    </DockPanel>

    <DockPanel 
        Height="3"
        Background="Black"></DockPanel>

    <DockPanel LastChildFill="True" Height="100">
        <StackPanel Name="LeftMenuWrapper"
                    DockPanel.Dock="Left"
                    Background="Yellow">
            <TextBlock 
                    Text="This is some text that is longer."/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Right"
                    Background="Blue">
        </StackPanel>
    </DockPanel>
</StackPanel>

Answer 1

LeftMenuWrapper의 실제 전체에 바인딩하십시오.

 <StackPanel>
    <DockPanel LastChildFill="True" Height="100" >
        <StackPanel Width="{Binding ElementName=LeftMenuWrapper, Path=ActualWidth}" 
                    DockPanel.Dock="Left"
                    Background="Yellow">
            <TextBlock
                Text="This is some text."/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Right"
                    Background="Orange">
        </StackPanel>
    </DockPanel>

    <DockPanel 
        Height="3"
        Background="Black"></DockPanel>

    <DockPanel LastChildFill="True" Height="100">
        <StackPanel Name="LeftMenuWrapper"
                    DockPanel.Dock="Left"
                    Background="Yellow">
            <TextBlock 
                    Text="This is some text that is longer."/>
        </StackPanel>
        <StackPanel DockPanel.Dock="Right"
                    Background="Blue">
        </StackPanel>
    </DockPanel>
</StackPanel>

이 작업을 수행하는 또 다른 방법으로 아스날에 추가하기 위해. 그리드의 issharedscope 속성을 사용할 수도 있습니다.

   <StackPanel Grid.IsSharedSizeScope="True">
      <Grid Height="100">
         <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" SharedSizeGroup="TextHolder"/>
            <ColumnDefinition Width="*"/>
         </Grid.ColumnDefinitions>
         <Border Background="Yellow">
            <TextBlock Text="This is some text."/>
         </Border>
         <Border Grid.Column="1" Background="Orange"/>
      </Grid>
      <Border Height="3" Background="Black"/>
      <Grid Height="100">

            <ColumnDefinition Width="Auto" SharedSizeGroup="TextHolder"/>
            <ColumnDefinition Width="*"/>
         </Grid.ColumnDefinitions>
         <Border Background="Yellow">
            <TextBlock Text="This is some text that is longer."/>
         </Border>
         <Border Grid.Column="1" Background="Blue"/>
      </Grid>
   </StackPanel>
</Page>

Answer 2

당신은 이것을 사용하여 할 수 있습니다 Grids와 함께 SharedSizeGroup 대신에 DockPanel에스. 즉

<StackPanel Grid.IsSharedSizeScope="True">
    <Grid Height="100" >

        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <StackPanel Grid.Column="0" Width="{Binding ElementName=LeftMenuText, Path=Width}"
                                DockPanel.Dock="Left"
                                Background="Yellow">
            <TextBlock
                    Text="This is some text."/>
        </StackPanel>
        <StackPanel Grid.Column="1" DockPanel.Dock="Right"
                                Background="Orange">
        </StackPanel>
    </Grid>

    <DockPanel
      Height="3"
      Background="Black"></DockPanel>

    <Grid Height="100">

        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" SharedSizeGroup="A"/>
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <StackPanel Grid.Column="0" Name="LeftMenuWrapper"
                                DockPanel.Dock="Left"
                                Background="Yellow">
            <TextBlock
                            Text="This is some text that is longer."/>
        </StackPanel>
        <StackPanel Grid.Column="1" DockPanel.Dock="Right"
                                Background="Blue">
        </StackPanel>
    </Grid>
</StackPanel>

기억해야 할 주요 사항은 그리드 내부의 각 열을 제공하는 것입니다. SharedSizeGroup 같은 이름 ( "a"이 예에서)으로 추가 Grid.IsSharedSizeScope="True" 공유 부모에게 GridS ( StackPanel 포함 Grid이 예에서 s)
