我需要一个只有Yes&的组合框。不是它的选项。 这将在应用程序的任何地方使用，所以我想我会 制作一个继承自combobox的控件。我遇到了麻烦 搞清楚如何在控制中添加Y / N.我试过了： Public Class YesNoCombobox 继承ComboBox Sub New（） MyBase.New（） 如果Me.Items.Count = 0那么 Me.Items.Add（" N - No"） Me.Items.Add （Y - 是） 结束如果 结束次级 结束班级 这使N / Y增加了一倍，因为设计师在设计师 代码中也设置了N / Y.有没有人想过如何做到这一点？ 克里斯

I have a need to have a combo box that just has Yes & No as it options. This will be used everywhere in the application, so I thought I would make a control that inherits from combobox. I am having trouble figuring out how to add the Y/N in control. I tried: Public Class YesNoCombobox Inherits ComboBox Sub New() MyBase.New() If Me.Items.Count = 0 Then Me.Items.Add("N - No") Me.Items.Add("Y - Yes") End If End Sub End Class This doubles the N/Y because the designer places a N/Y in the designer code as well. Anyone have thoughts on how to do this? Chris

推荐答案

如果它只需要Y& N，不应该是布尔控件或列表框 控件，而不是ComboBox控件吗？ 使用ComboBox，我会比方说，这是一个很糟糕的设计用户界面的好例子。 UI'应该易于使用并且易于用户理解。用户 不要指望Y& ComboBoxes N回答。 你有什么理由认为你需要一个ComboBox吗？ " Chris" < no@spam>在留言中写道 新闻：eo ************** @ TK2MSFTNGP03.phx.gbl ... If it needs only Y & N, shouldn''t it be a boolean control or a listbox control, but not a ComboBox control? Using a ComboBox for this, I would say, is a good example of a poorly designed UI. UI''s should be easy to use and understand for users. Users don''t expect ComboBoxes for Y & N answers. Is there some reason why you feel you need a ComboBox for this?

是的，谢谢你的关注我的设计，但我们正在复制已经存在的 功能。他们喜欢它的样子，而且不值得为改变它而战斗。它运作良好，我仍然会像解决方案一样。 Chris

Yes, thank you for your concern on my design, but we are duplicating a functionality that already exists. They like the way it is and it is not worth fighting to change it. It works well and it I still would like a solution. Chris

我会使用复选框控件（布尔控制）:-)。 - MS Herfried K. Wagner MVP< URL ：http：//dotnet.mvps/> VB< URL：http：//classicvb/petition/>

I''d use a checkbox control ("boolean control") :-). -- M S Herfried K. Wagner M V P <URL:dotnet.mvps/> V B <URL:classicvb/petition/>
