操作說明：在方格之間共用調整大小屬性

  • 發行項

此範例示範如何在 Grid 元素之間共用資料行與資料列的調整大小資料，以讓大小保持一致。

範例

下列範例介紹兩個 Grid 元素當做父代 DockPanel 的子項目。 Grid 的 IsSharedSizeScope 附加屬性定義在父代 DockPanel 上。

此範例會透過使用兩個 Button 元素來操縱屬性值；每個元素代表其中一個布林值屬性值。 當 IsSharedSizeScope 屬性的值設定為 true 時，不論資料列或資料行的內容為何，SharedSizeGroup 的每個資料行或資料列成員都會共用調整大小資訊。

<DockPanel Name="dp1" Grid.IsSharedSizeScope="False" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="10">

...

   <StackPanel Orientation="Horizontal" DockPanel.Dock="Top">  
       <Button Click="setTrue" Margin="0,0,10,10">Set IsSharedSizeScope="True"</Button>
       <Button Click="setFalse" Margin="0,0,10,10">Set IsSharedSizeScope="False"</Button>
   </StackPanel> 

   <StackPanel Orientation="Horizontal" DockPanel.Dock="Top">

   <Grid ShowGridLines="True" Margin="0,0,10,0">
     <Grid.ColumnDefinitions>
       <ColumnDefinition SharedSizeGroup="FirstColumn"/>
       <ColumnDefinition SharedSizeGroup="SecondColumn"/>
     </Grid.ColumnDefinitions>
     <Grid.RowDefinitions>
       <RowDefinition Height="Auto" SharedSizeGroup="FirstRow"/>
     </Grid.RowDefinitions>

       <Rectangle Fill="Silver" Grid.Column="0" Grid.Row="0" Width="200" Height="100"/>
       <Rectangle Fill="Blue" Grid.Column="1" Grid.Row="0" Width="150" Height="100"/>

       <TextBlock Grid.Column="0" Grid.Row="0" FontWeight="Bold">First Column</TextBlock>
       <TextBlock Grid.Column="1" Grid.Row="0" FontWeight="Bold">Second Column</TextBlock>
   </Grid>

   <Grid ShowGridLines="True">
     <Grid.ColumnDefinitions>
       <ColumnDefinition SharedSizeGroup="FirstColumn"/>
       <ColumnDefinition SharedSizeGroup="SecondColumn"/>
     </Grid.ColumnDefinitions>
     <Grid.RowDefinitions>        
       <RowDefinition Height="Auto" SharedSizeGroup="FirstRow"/>
     </Grid.RowDefinitions>

       <Rectangle Fill="Silver" Grid.Column="0" Grid.Row="0"/>
       <Rectangle Fill="Blue" Grid.Column="1" Grid.Row="0"/>

       <TextBlock Grid.Column="0" Grid.Row="0" FontWeight="Bold">First Column</TextBlock>
       <TextBlock Grid.Column="1" Grid.Row="0" FontWeight="Bold">Second Column</TextBlock>
   </Grid>
   
   </StackPanel>

   <TextBlock Margin="10" DockPanel.Dock="Top" Name="txt1"/>

下列程式碼後置範例會處理按鈕 Click 事件引發的方法。 此範例會將這些方法呼叫的結果寫入到 TextBlock 元素，這些元素會使用相關的 get 方法將新屬性值輸出成字串。

private void setTrue(object sender, System.Windows.RoutedEventArgs e)
{
    Grid.SetIsSharedSizeScope(dp1, true);
    txt1.Text = "IsSharedSizeScope Property is set to " + Grid.GetIsSharedSizeScope(dp1).ToString();
}

private void setFalse(object sender, System.Windows.RoutedEventArgs e)
{
    Grid.SetIsSharedSizeScope(dp1, false);
    txt1.Text = "IsSharedSizeScope Property is set to " + Grid.GetIsSharedSizeScope(dp1).ToString();
}

Private Sub setTrue(ByVal sender As Object, ByVal args As RoutedEventArgs)

    Grid.SetIsSharedSizeScope(dp1, True)
    txt1.Text = "IsSharedSizeScope Property is set to " + Grid.GetIsSharedSizeScope(dp1).ToString()
End Sub

Private Sub setFalse(ByVal sender As Object, ByVal args As RoutedEventArgs)

    Grid.SetIsSharedSizeScope(dp1, False)
    txt1.Text = "IsSharedSizeScope Property is set to " + Grid.GetIsSharedSizeScope(dp1).ToString()
End Sub
