當我點擊另一個按鈕時如何更改按鈕的顏色？

Question

我想要做的是當我點擊btn1（將啓用組合框），我會選擇組合框中的顏色（例如紅色），然後單擊btnSave。 btn1的顏色將變成紅色（永久）。

Answer 1

我以爲用vb

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load 
    Dim dt As New DataTable 
    dt.Columns.Add("no", GetType(String)) 
    dt.Columns.Add("color", GetType(String)) 
    dt.Rows.Add("1", "Red") 
    dt.Rows.Add("2", "Blue") 

    ComboBox1.DataSource = dt 
    ComboBox1.DisplayMember = dt.Columns("color").ToString 
    ComboBox1.ValueMember = dt.Columns("no").ToString 
    ComboBox1.Enabled = False 
End Sub 


Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
    ComboBox1.Enabled = True 
End Sub 

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click 
    If ComboBox1.Enabled <> False Then 
     Button1.BackColor = Color.FromName(ComboBox1.Text) 
    End If 
End Sub
