示例

下面的示例演示如何通过使用可扩展应用程序标记语言 (XAML) 或代码来创建和使用 Grid 的实例。此示例使用三个 ColumnDefinitions 和三个 RowDefinitions 来创建包含九个单元格的网格（如工作表）。每个单元格都包含一个表示数据的 TextBlock 元素，并且首行包含应用了 ColumnSpan 属性的 TextBlock。为了显示每个单元格的边界，已启用了 ShowGridLines 属性。

Public Sub New()
    WindowTitle = "Grid Sample"
    'Create a Grid as the root Panel element
    Dim myGrid As New Grid()
    myGrid.Height = 100
    myGrid.Width = 250
    myGrid.ShowGridLines = True
    myGrid.HorizontalAlignment = Windows.HorizontalAlignment.Left
    myGrid.VerticalAlignment = Windows.VerticalAlignment.Top

    ' Define and Add the Rows and Columns
    Dim colDef1 As New ColumnDefinition
    Dim colDef2 As New ColumnDefinition
    Dim colDef3 As New ColumnDefinition
    myGrid.ColumnDefinitions.Add(colDef1)
    myGrid.ColumnDefinitions.Add(colDef2)
    myGrid.ColumnDefinitions.Add(colDef3)

    Dim rowDef1 As New RowDefinition
    Dim rowDef2 As New RowDefinition
    Dim rowDef3 As New RowDefinition
    Dim rowDef4 As New RowDefinition
    myGrid.RowDefinitions.Add(rowDef1)
    myGrid.RowDefinitions.Add(rowDef2)
    myGrid.RowDefinitions.Add(rowDef3)
    myGrid.RowDefinitions.Add(rowDef4)

    Dim txt1 As New TextBlock
    txt1.Text = "2004 Products Shipped"
    txt1.FontSize = 20
    txt1.FontWeight = FontWeights.Bold
    Grid.SetColumnSpan(txt1, 3)
    Grid.SetRow(txt1, 0)
    myGrid.Children.Add(txt1)

    Dim txt2 As New TextBlock
    txt2.Text = "Quarter 1"
    txt2.FontSize = 12
    txt2.FontWeight = FontWeights.Bold
    Grid.SetRow(txt2, 1)
    Grid.SetColumn(txt2, 0)
    myGrid.Children.Add(txt2)

    Dim txt3 As New TextBlock
    txt3.Text = "Quarter 2"
    txt3.FontSize = 12
    txt3.FontWeight = FontWeights.Bold
    Grid.SetRow(txt3, 1)
    Grid.SetColumn(txt3, 1)
    myGrid.Children.Add(txt3)

    Dim txt4 As New TextBlock
    txt4.Text = "Quarter 3"
    txt4.FontSize = 12
    txt4.FontWeight = FontWeights.Bold
    Grid.SetRow(txt4, 1)
    Grid.SetColumn(txt4, 2)
    myGrid.Children.Add(txt4)

    Dim txt5 As New TextBlock
    txt5.Text = "50,000"
    Grid.SetRow(txt5, 2)
    Grid.SetColumn(txt5, 0)
    myGrid.Children.Add(txt5)

    Dim txt6 As New Controls.TextBlock
    txt6.Text = "100,000"
    Grid.SetRow(txt6, 2)
    Grid.SetColumn(txt6, 1)
    myGrid.Children.Add(txt6)

    Dim txt7 As New TextBlock
    txt7.Text = "150,000"
    Grid.SetRow(txt7, 2)
    Grid.SetColumn(txt7, 2)
    myGrid.Children.Add(txt7)

    ' Add the final TextBlock Cell to the Grid
    Dim txt8 As New TextBlock
    txt8.FontSize = 16
    txt8.FontWeight = FontWeights.Bold
    txt8.Text = "Total Units: 300000"
    Grid.SetRow(txt8, 3)
    Grid.SetColumnSpan(txt8, 3)
    myGrid.Children.Add(txt8)

    Me.Content = myGrid
