如何:在网格之间共享大小调整属性

此示例演示如何在 Grid 元素之间共享列和行的大小调整数据,以使大小调整保持一致。

示例

下面的示例引入了两个 Grid 元素作为父 DockPanel 的子元素。 GridIsSharedSizeScope 附加属性在父级 DockPanel 上定义。

该示例通过使用两个 Button 元素处理属性值;每个元素表示其中一个布尔属性值。 当将 IsSharedSizeScope 属性值设置为 true 时,无论行或列的内容如何,SharedSizeGroup 的每个列或行成员都将共享大小调整信息。

<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"/>

以下代码隐藏示例处理按钮 Click 事件引发的方法。 该示例将这些方法调用的结果写入 TextBlock 元素,这些元素使用相关的 get 方法以字符串形式输出新属性值。

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
