How to: Share Sizing Properties Between Grids

This example shows how to share the sizing data of columns and rows between Grid elements in order to keep sizing consistent.

Example

The following example introduces two Grid elements as child elements of a parent DockPanel. The IsSharedSizeScope attached property of Grid is defined on the parent DockPanel.

The example manipulates the property value by using two Button elements; each element represents one of the Boolean property values. When the IsSharedSizeScope property value is set to true, each column or row member of a SharedSizeGroup shares sizing information, regardless of the content of a row or column.

<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"/>

The following code-behind example handles the methods that the button Click event raises. The example writes the results of these method calls to TextBlock elements that use related get methods to output the new property values as strings.

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

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

Public 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

Public 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
