Question

我在vb.net中有10 x 10 tablelayoutpanel和10 x 10数组。我希望能够用鼠标单击一个单元格，并且该特定单元格将更改颜色，相应的数组元素将为1.未单击的单元格将在数组中具有0，依此类推。单击另一个单元格，单元格会更改颜色，相应的数组元素会更新。

在单元格上单击鼠标按钮后，我不确定如何更改tableLayoutPanel中单个单元格的颜色。

尝试通过谷歌搜索寻找想法，但似乎无法找到具体的东西。任何帮助将不胜感激。

细胞不是对照，不能单独控制背面颜色。您可以在每个单元格中放置一个面板，并在运行时添加处理程序。此示例将切换TLP中每个单元格的红色和蓝色之间的颜色

Private panels As New Dictionary(Of Panel, Point)()
Private values(9, 9) As Integer

Private Sub PanelClick(sender As Object, e As EventArgs)
    Dim s = DirectCast(sender, Panel)
    Dim x = panels(s).X
    Dim y = panels(s).Y
    values(x, y) = If(values(x, y) = 0, 1, 0)
    s.BackColor = If(values(x, y) = 0, Color.Red, Color.Blue)
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    For i = 0 To TableLayoutPanel1.ColumnCount - 1
        For j = 0 To TableLayoutPanel1.RowCount - 1
            Dim s = TableLayoutPanel1.GetControlFromPosition(i, j)
            If s IsNot Nothing Then
                Dim p = DirectCast(TableLayoutPanel1.GetControlFromPosition(i, j), Panel)
                panels.Add(p, New Point(i, j))
                AddHandler p.Click, AddressOf PanelClick
            End If
        Next
    Next
End Sub
