Contoh

Contoh berikut menunjukkan cara mengatur ItemHeight properti dalam Extensible Application Markup Language (XAML).

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" WindowTitle="WrapPanel Properties Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Orientation="Horizontal" Background="Azure" ItemWidth="25" ItemHeight="25" Height="200" Width="200">
            <Button Width="200">Button 1</Button>
            <Button>Button 2</Button>
            <Button>Button 3</Button>
        </WrapPanel>
  </Border>    
</Page>

Contoh berikut menunjukkan cara mengatur ItemHeight properti dengan menggunakan kode.

// Create the application's main window
mainWindow = gcnew System::Windows::Window();
mainWindow->Title = "WrapPanel Sample";


// Instantiate a new WrapPanel and set properties
myWrapPanel = gcnew WrapPanel();
myWrapPanel->Background = Brushes::Azure;
myWrapPanel->Orientation = Orientation::Horizontal;
myWrapPanel->ItemHeight = 25;

myWrapPanel->ItemWidth = 75;
myWrapPanel->Width = 150;
myWrapPanel->HorizontalAlignment = HorizontalAlignment::Left;
myWrapPanel->VerticalAlignment = VerticalAlignment::Top;

// Define 3 button elements. Each button is sized at width of 75, so the third button wraps to the next line.
btn1 = gcnew Button();
btn1->Content = "Button 1";
btn2 = gcnew Button();
btn2->Content = "Button 2";
btn3 = gcnew Button();
btn3->Content = "Button 3";

// Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel->Children->Add(btn1);
myWrapPanel->Children->Add(btn2);
myWrapPanel->Children->Add(btn3);

// Add the WrapPanel to the MainWindow as Content
mainWindow->Content = myWrapPanel;
mainWindow->Show();

// Create the application's main window
mainWindow = new System.Windows.Window();
mainWindow.Title = "WrapPanel Sample";


// Instantiate a new WrapPanel and set properties
myWrapPanel = new WrapPanel();
myWrapPanel.Background = System.Windows.Media.Brushes.Azure;
myWrapPanel.Orientation = Orientation.Horizontal;
myWrapPanel.Width = 200;
myWrapPanel.HorizontalAlignment = HorizontalAlignment.Left;
myWrapPanel.VerticalAlignment = VerticalAlignment.Top;

// Define 3 button elements. The last three buttons are sized at width 
// of 75, so the forth button wraps to the next line.
btn1 = new Button();
btn1.Content = "Button 1";
btn1.Width = 200;
btn2 = new Button();
btn2.Content = "Button 2";
btn2.Width = 75;
btn3 = new Button();
btn3.Content = "Button 3";
btn3.Width = 75;
btn4 = new Button();
btn4.Content = "Button 4";
btn4.Width = 75;

// Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1);
myWrapPanel.Children.Add(btn2);
myWrapPanel.Children.Add(btn3);
myWrapPanel.Children.Add(btn4);

// Add the WrapPanel to the MainWindow as Content
mainWindow.Content = myWrapPanel;
mainWindow.Show();

WindowTitle = "WrapPanel Sample"

' Instantiate a new WrapPanel and set properties
Dim myWrapPanel As New WrapPanel()
myWrapPanel.Background = Brushes.Azure
myWrapPanel.Orientation = Orientation.Horizontal

myWrapPanel.Width = 200
myWrapPanel.HorizontalAlignment = Windows.HorizontalAlignment.Left
myWrapPanel.VerticalAlignment = Windows.VerticalAlignment.Top

' Define 3 button elements. The last three buttons are sized at width 
' of 75, so the forth button wraps to the next line.
Dim btn1 As New Button()
btn1.Content = "Button 1"
btn1.Width = 200
Dim btn2 As New Button()
btn2.Content = "Button 2"
btn2.Width = 75
Dim btn3 As New Button()
btn3.Content = "Button 3"
btn3.Width = 75
Dim btn4 As New Button()
btn4.Content = "Button 4"
btn4.Width = 75

' Add the buttons to the parent WrapPanel using the Children.Add method.
myWrapPanel.Children.Add(btn1)
myWrapPanel.Children.Add(btn2)
myWrapPanel.Children.Add(btn3)
myWrapPanel.Children.Add(btn4)

' Add the WrapPanel to the Page as Content
Me.Content = myWrapPanel

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" WindowTitle="WrapPanel Sample">
  <Border HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="2">
        <WrapPanel Background="LightBlue" Width="200" Height="100">

            <Button>Button 2</Button>
            <Button>Button 3</Button>

Keterangan

Jika properti ini tidak diatur (atau jika diatur ke Auto dalam XAML atau ke Double.NaN dalam kode), ukuran partisi tata letak sama dengan ukuran elemen turunan yang diinginkan.

Elemen anak dari WrapPanel properti tinggi mungkin diatur secara eksplisit. ItemHeight menentukan ukuran partisi tata letak yang dicadangkan oleh WrapPanel untuk elemen anak. Akibatnya, ItemHeight lebih diutamakan daripada tinggi elemen sendiri.

Penggunaan Atribut XAML

<object ItemHeight="double"/>  
- or -  
<object ItemHeight="qualifiedDouble"/>  
- or -  
<object ItemHeight="Auto"/>
