WPF學習日誌 ~ Grid ~

Grid這個"容器"相較之前的容器來看，顯的比較複雜一些，需要設定的東西比較多，下面用簡單的程式碼展示一下基本的功能，希望大家對於Grid能有一些基本的了解

Dim gd As Grid

    Private Sub Window1_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded
        gd = New Grid
        Me.Title = "Grid Test"
        ''設定Form的大小跟Content的長、寬是一樣的
        Me.SizeToContent = Windows.SizeToContent.WidthAndHeight
        Me.Content = gd
        ''為了方面觀看變化，我們把隔線設定為顯示
        gd.ShowGridLines = True
        ''為了範例需要我們把新增欄、列的新增跟按鈕的新增分開處理
        For iRow As Integer = 0 To 4
            ''新增Grid的列
            Dim rd = New RowDefinition
            If iRow = 4 Then
                ''最後一列為了展示跨越欄位的button，這邊做特殊設定
                ''可以自行修改看看GridUnitType的部分看看有什麼不同
                rd.Height = New GridLength(100, GridUnitType.Star)
            Else
                rd.Height = GridLength.Auto
            End If
            gd.RowDefinitions.Add(rd)
        Next
        For iCol As Integer = 0 To 4
            ''新增Grid的欄
            Dim cd As New ColumnDefinition
            If iCol = 4 Then
                cd.Width = New GridLength(100, GridUnitType.Star)
            Else
                cd.Width = GridLength.Auto
            End If
            gd.ColumnDefinitions.Add(cd)
        Next

        For z As Integer = 0 To 3
            For x As Integer = 0 To 3
                Dim btn As New Button
                btn.Name = "Button" & z & "_" & x
                btn.Content = "Button " & z & "-" & x
                btn.Margin = New Thickness(2)
                Grid.SetColumn(btn, x)
                Grid.SetRow(btn, z)
                gd.Children.Add(btn)
            Next
        Next
        Dim btnBig As New Button
        btnBig.Name = "btnBig"
        btnBig.Content = "Big Button"
        btnBig.Margin = New Thickness(2)
        Grid.SetRow(btnBig, 4)
        Grid.SetColumn(btnBig, 0)
        ''設定跨越Grid的三格，如果是跨越Row的話是用SetRowSpan
        Grid.SetColumnSpan(btnBig, 3)
        gd.Children.Add(btnBig)
    End Sub
