子字符串上的组合框自动完成 [英] ComboBox AutoComplete on SubString

问题描述

在我的一个 WinForms 应用程序中，我有一个带有 ComboBox 的窗口，供用户从中选择客户.

In one of my WinForms applications, I have a window with a ComboBox for the user to select a customer from.

此列表框中的客户采用以下格式:CustomerID - CustomerName"，例如004540 - NorthWind Traders"

The customers in this list box are in this format : "CustomerID - CustomerName", for example "004540 - NorthWind Traders"

本机 WinForms 组合框有一个内置的自动完成功能，而且效果很好:问题在于它只能从组合框列表中每个项目的字符串的开头匹配，而不是从任何地方(子字符串)匹配.

The native WinForms combobox has an autocomplete feature built-in and it works well: the problem is that it only works by matching from the beginning of the string of each item of the combobox's list and not from anywhere (substring).

我希望我的用户能够做的是输入 CustomerID 或 CustomerName 的任何一种类型，因为高级用户熟悉大多数 CustomerID，而新员工将受益于能够输入 CustomerName 并获得自动完成功能.这意味着我实际上想从列表中寻找最佳匹配，其中输入的文本是 ComboBox 项的子字符串.

What I would like my users to be able to do is to either type of the CustomerID or CustomerName, as senior users are familiar with most CustomerIDs while new recruits would benefit from being able to type the CustomerName in and get the AutoComplete anyway. That means that I actually want to look for the best match from the list where the inputted text is a substring of the ComboBox item.

通常针对这种情况建议的解决方案是创建一个仅在用户键入时显示的隐藏列表框，但我对此并不满意，因为它感觉像是快速破解并且不容易重用，并且与标准 ComboBox 控件相比，其外观和行为可能不一致.

A solution often suggested for this kind of scenario is to create a hidden list box that only shows up when the user types, but I'm not happy with that as it feels like a quick hack and is not easily reusable, and may look and behave inconsistently compared to the standard ComboBox control.

我尝试自己使用 DroppedDown 属性来实现这个列表，并使用 SelectedIndex 来设置项目，但是当我这样做时组合框的文本框的内容会被重置，而我只想要最佳匹配item"从组合框列表中突出显示(我需要建议"而不是附加"，附加模式无论如何都不能真正与子字符串匹配一起使用).

I've tried to implement this myself using the DroppedDown property to make the list appear and use SelectedIndex to set the item but the content of the combobox's textbox is reset when I do that, while I only would like the "best matching item" to be highlighted from the ComboBox lists (I need "Suggest" and not "Append", Append-mode can not be really be used with substring-matching anyway).

我认为一定有更好的方法吗?如果有人知道这样做的自定义/第 3 方控件，我也不反对购买.

I think that there must be a better way? If anyone knows of a custom / 3rd Party control doing this, I'm not against buying one either.

谢谢.

推荐答案

好吧，我有一些代码供您尝试.它不是一个组合框，而是一个自动完成的文本框，带有按照您的要求执行的修改.

Well, I have some code for you to try. Its not a combo box, but it is an autocomplete text box with modifications that perform as you are requesting.

将代码复制到新表单中.然后在做任何其他事情之前，保存并构建.然后转到表单设计器并将一个新的 ClsCustomAutoCompleteTextbox 拖到您的表单上.

Copy the code into a new form. Then before doing anything else, save and build. Then go to the form designer and drag a new ClsCustomAutoCompleteTextbox onto your form.

然后你应该能够运行它.我确实意识到您想要 C#(至少现在我意识到了这一点).在 VB 中试试这个，看看这是不是你想要的，我可以把它转换成 C#.

Then you should be able to run it. I do realize that you are wanting C# (At least now I realize that). Try this in VB and see if this is what you want, and I can convert it to C#.
