Question

我需要在1个组合框中选择的项目将在另一个组合框中显示此选择中的未决项目。我不在项目中使用SQL，EXEL，ACCESS或VBA。我在winforms中添加了自己的项目。它应该看起来像这样的声音： http://imgur.com/BYQNVzd 非常感谢您的帮助。

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    If ComboBox1.SelectedIndex = 0 Then
        ' Index 0 is BMW
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"X5", "X6", "7-series", "5-series", "3-series"})
    ElseIf ComboBox1.SelectedIndex = 1 Then
        ' Toyota
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"Teana", "Camry"})
    ElseIf ComboBox1.SelectedIndex = 2 Then
        ' kia
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"Rio"})
    End If
End Sub

看起来像这样

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    If ComboBox1.SelectedIndex = 0 Then
        ' Index 0 is BMW
        ComboBox2.Items.Clear()
        ComboBox2.Items.AddRange({"X5", "X6", "7-series", "5-series", "3-series"})
    ElseIf ComboBox1.SelectedIndex = 1 Then
        ' Toyota

    End If
End Sub

组合框值取决于另一个组合框的选择
