组合框或列表框？ [英] Combobox or List box?

问题描述

我很好奇我是否应该使用列表框或组合框来查找仓库部件号，然后点击它时触发事件。我希望能够单击该号码，然后从串行端口发送特定命令。我目前使用一些超链接来做这个，但现在有很多，下拉列表将有助于选择和激发相同的命令，就像它是超链接一样。



这是我的代码，当单击HC1_101部件的超链接时...我可以用列表框替换它来发送相同的命令吗？我可以将链接添加到下拉列表吗？

I was curious if I should use a listbox or combobox to look up warehouse part numbers and then fire an event if it is clicked. I want to be able to click that number and then send a specific command out a serial port. I currently use a selection of hyperlinks to do this but there are now to many and a dropdown list would be helpful to select from and fire the same command as if it was the hyperlink.

Here is my code for when a hyperlink is clicked for part HC1_101... could I replace this with a listbox to send the same command? Can I just add the links to the dropdown list?

private void linkLabel_HC1_101_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    if (serialPort1.IsOpen)
    {
        var content = new List<byte>();
        content.Add(2);
        content.AddRange(Encoding.ASCII.GetBytes("01P00101##"));
        content.Add(3);
        byte[] buffer = content.ToArray();
        serialPort1.Write(buffer, 0, buffer.Length);
    }
}

推荐答案

哪个更好？是一个我们很难给出正确和准确答案的问题。我们对您的项目一无所知。



以下是一些指向Windows窗体版控件的MSDN链接：

ComboBox类 [ ^ ]

ListBox类 [ ^ ]



在事件列表中，您将找到必须使用的代理（事件处理程序）。

"Which is better?" is a question we can hardly give a correct and precise answer. We don't know anything of your project.

Here are some MSDN links to the Windows Forms version of the controls:
ComboBox class[^]
ListBox class[^]

In their event lists, you will find which delegate (event handler) you will have to use.

选择完全取决于你想要什么。 ComboBox 在顶部添加文本框输入。你打算用这部分控制做什么？如果你想在其中输入内容（即使是为了类似搜索的选择样式），你需要 ComboBox 。如果您希望能够输入列表中未显示的某些文本，还需要 ComboBox 。顺便说一下，列表部分的一个可能的应用是将历史存储在文本框部分的输入中。在所有其他情况下，它是 ListBox 。



就这么简单。

The choice depends solely on what you want. ComboBox adds a text box input on top. What are you going to do with this part of control? If you want to input something in it (even for the purpose of search-like selection style), you need ComboBox. If you want to be able to input some text not shown in the list, you also need ComboBox. By the way, one possible application of the list part would be storing the history in input in text box part. In all other cases, it's ListBox.

As simple as that.
