两个CheckBox如何能相互制约，怎么设置属性才能做到

[小小蔷薇]

两个CheckBox，选第一个就不选第二个，选第二个就不选第一个，应该怎么设置CheckBox的属性啊？

用的是VS2010

[bdmh]

就俩个，用代码控制吧

[二当家]

checkboxlist 有这个组件的

[claymore1114]

js控制，要不 用radio

[小小蔷薇]

VB.net不能在控件的属性里直接设置吗？

代码控制：

 Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
        If Me.CheckBox1.Checked = True Then
            Me.CheckBox2.Checked = False
        End If
    End Sub

    Private Sub CheckBox2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox2.CheckedChanged
        If Me.CheckBox2.Checked = True Then
            Me.CheckBox1.Checked = False
        End If
    End Sub

也可以换成单选框。

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Me.CheckBox2.Checked = Not Me.CheckBox1.Checked()
End Sub

Private Sub CheckBox2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox2.CheckedChanged
Me.CheckBox1.Checked = Not Me.CheckBox2.Checked()
End Sub

用RadioButton比较方便

[Tosp2012]

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
  Me.CheckBox2.Checked = Not Me.CheckBox1.Checked()
  End Sub
  Private Sub CheckBox2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox2.CheckedChanged
  Me.CheckBox1.Checked = Not Me.CheckBox2.Checked()
  End Sub

代码控制：

VB.NET code
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If Me.CheckBox1.Checked = True Then
Me.CheckBox2.Checked = False
End If
End Sub

Private Sub CheckBox2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox2.CheckedChanged
If Me.CheckBox2.Checked = True Then
Me.CheckBox1.Checked = False
End If
End Sub



也可以换成单选框。

代码判断。。。两个checkbox直接if..else就可以。。

如果更多checkbox，可以写个方法遍历这些checkobx，看是否己有选中项。。。

------------------------

如果是单选，为什么不用单选按钮（radiobutton）？

用户看上去就知道是单选，用户也只能单选，少了些程序的判断，也会避免用户的多余操作
