组合框里的文字默认设置了颜色，鼠标进入时颜色就变了，现在鼠标进入和离开时不想有任何的动作，也就是文字不变颜色，

MouseEnter事件写了一大堆代码，有什么简洁的方法吗？

Select Case True
    Case e.sender.name.StartsWith("ComboBoxFilterCol")
        If e.sender.text = "筛选列" Then
            e.sender.ForeColor = Color.Silver
        Else
            e.sender.ForeColor = Color.Black
        End If
    Case e.sender.name.StartsWith("ComboBoxFilterList")
        If e.sender.text = "条件" Then
            e.sender.ForeColor = Color.Silver
        Else
            e.sender.ForeColor = Color.Black
        End If
    Case e.sender.name.StartsWith("CheckedComboBoxFilter")
        If e.sender.text = "筛选值" Then
            e.sender.ForeColor = Color.Silver
        Else
            e.sender.ForeColor = Color.Black
        End If
End Select
