以下示例演示如何使用 Extensible Application Markup Language (XAML) 或代码创建和使用 Grid 实例。此示例使用三个 ColumnDefinition 对象和三个 RowDefinition 对象来创建一个具有九个单元格的网格，例如在工作表中。每个单元格都包含一个表示数据的 TextBlock 元素，顶部行包含一个应用了 ColumnSpan 属性的 TextBlock 。为了显示每个单元格的边界，启用了 ShowGridLines 属性。

// Create the application's main window mainWindow = new Window(); mainWindow.Title = "Grid Sample"; // Create the Grid Grid myGrid = new Grid(); myGrid.Width = 250; myGrid.Height = 100; myGrid.HorizontalAlignment = HorizontalAlignment.Left; myGrid.VerticalAlignment = VerticalAlignment.Top; myGrid.ShowGridLines = true; // Define the Columns ColumnDefinition colDef1 = new ColumnDefinition(); ColumnDefinition colDef2 = new ColumnDefinition(); ColumnDefinition colDef3 = new ColumnDefinition(); myGrid.ColumnDefinitions.Add(colDef1); myGrid.ColumnDefinitions.Add(colDef2); myGrid.ColumnDefinitions.Add(colDef3); // Define the Rows RowDefinition rowDef1 = new RowDefinition(); RowDefinition rowDef2 = new RowDefinition(); RowDefinition rowDef3 = new RowDefinition(); RowDefinition rowDef4 = new RowDefinition(); myGrid.RowDefinitions.Add(rowDef1); myGrid.RowDefinitions.Add(rowDef2); myGrid.RowDefinitions.Add(rowDef3); myGrid.RowDefinitions.Add(rowDef4); // Add the first text cell to the Grid TextBlock txt1 = new TextBlock(); txt1.Text = "2005 Products Shipped"; txt1.FontSize = 20; txt1.FontWeight = FontWeights.Bold; Grid.SetColumnSpan(txt1, 3); Grid.SetRow(txt1, 0); // Add the second text cell to the Grid TextBlock txt2 = new TextBlock(); txt2.Text = "Quarter 1"; txt2.FontSize = 12; txt2.FontWeight = FontWeights.Bold; Grid.SetRow(txt2, 1); Grid.SetColumn(txt2, 0); // Add the third text cell to the Grid TextBlock txt3 = new TextBlock(); txt3.Text = "Quarter 2"; txt3.FontSize = 12; txt3.FontWeight = FontWeights.Bold; Grid.SetRow(txt3, 1); Grid.SetColumn(txt3, 1); // Add the fourth text cell to the Grid TextBlock txt4 = new TextBlock(); txt4.Text = "Quarter 3"; txt4.FontSize = 12; txt4.FontWeight = FontWeights.Bold; Grid.SetRow(txt4, 1); Grid.SetColumn(txt4, 2); // Add the sixth text cell to the Grid TextBlock txt5 = new TextBlock(); Double db1 = new Double(); db1 = 50000; txt5.Text = db1.ToString(); Grid.SetRow(txt5, 2); Grid.SetColumn(txt5, 0); // Add the seventh text cell to the Grid TextBlock txt6 = new TextBlock(); Double db2 = new Double(); db2 = 100000; txt6.Text = db2.ToString(); Grid.SetRow(txt6, 2); Grid.SetColumn(txt6, 1); // Add the final text cell to the Grid TextBlock txt7 = new TextBlock(); Double db3 = new Double(); db3 = 150000; txt7.Text = db3.ToString(); Grid.SetRow(txt7, 2); Grid.SetColumn(txt7, 2); // Total all Data and Span Three Columns TextBlock txt8 = new TextBlock(); txt8.FontSize = 16; txt8.FontWeight = FontWeights.Bold; txt8.Text = "Total Units: " + (db1 + db2 + db3).ToString(); Grid.SetRow(txt8, 3); Grid.SetColumnSpan(txt8, 3); // Add the TextBlock elements to the Grid Children collection myGrid.Children.Add(txt1); myGrid.Children.Add(txt2); myGrid.Children.Add(txt3); myGrid.Children.Add(txt4); myGrid.Children.Add(txt5); myGrid.Children.Add(txt6); myGrid.Children.Add(txt7); myGrid.Children.Add(txt8); // Add the Grid as the Content of the Parent Window Object mainWindow.Content = myGrid; mainWindow.Show ();

任一方法都会生成一个看起来非常相似的用户界面，如下所示。
