SubString上的ComboBox AutoComplete

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。

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

本机WinFormscombobox具有内置的自动完成function，它运行良好：问题是它只能通过从combobox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）进行匹配。

我希望我的用户能够做的是CustomerID或CustomerName的类型，因为高级用户熟悉大多数CustomerID，而新员工可以从中输入CustomerName并获得AutoComplete。 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。

通常建议用于这种情况的解决方案是创建一个隐藏的列表框，仅在用户输入时显示，但我对此不满意，因为它感觉像是一个快速的黑客并且不容易重复使用，并且可能看起来和与标准ComboBox控件相比，行为不一致。

我尝试使用DroppedDown属性来实现这一点，使列表出现并使用SelectedIndex来设置项目，但是当我这样做时，combobox文本框的内容被重置，而我只希望“最匹配的项目”到从ComboBox列表中突出显示（我需要“建议”而不是“追加”，无论如何，追加模式不能真正用于子串匹配）。

我认为必须有更好的方法吗？ 如果有人知道自定义/第三方控制这样做，我也不反对买一个。

谢谢。

PS：我使用.Net Framework 3.5在WinForms的C＃中编程。

好吧，我有一些代码供你试试。 它不是一个combobox，但它是一个自动完成文本框，其修改可以按照您的要求执行。

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新的ClsCustomAutoCompleteTextbox拖到表单上。

然后你应该能够运行它。 我确实意识到你想要C＃（至少现在我意识到了这一点）。 在VB中尝试这个，看看这是否是你想要的，我可以将它转换为C＃。

我不知道这是否是一个选项，但是，例如你可以做这样的事情：

  private void Main_Load(object sender, EventArgs e) { DataTable dt = new DataTable(); dt.Columns.Add("colCustomers", typeof(string)); dt.Rows.Add(new object[] { "1 John" }); dt.Rows.Add(new object[] { "2 Kate" }); dt.Rows.Add(new object[] { "3 Jill" }); comboBox1.DataSource = dt.DefaultView; //allows us to filter the results comboBox1.DisplayMember = "Col1"; } private void comboBox1_TextChanged(object sender, EventArgs e) { if (comboBox1.SelectedIndex == -1) { dt.DefaultView.RowFilter = "colCustomers LIKE '%" + comboBox1.Text + "%'"; } } 

当然，您也可以使用搜索和定位而不是过滤，但由于可能有很多客户，我认为最好只留下匹配的客户。 当用户删除他的条目时，它应该再次显示所有人。 代码可能会受益于对您的需求的一些调整，但您必须尝试提出您想要的东西。

Answer 4

你可以使用这个类：

 public partial class MyComboBox : ComboBox { private IList 

Answer 5

这是我的数据绑定combobox的代码（在我的例子中是一个Access DB）。 您将combobox和列表框添加到窗体。 然后，使用下面的代码作为参考，如下所示：

1. 如何更新数据绑定combobox
2. 添加事件处理程序，以便在combobox中使用箭头键时，它会遍历列表框中的结果。
3. 使用计时器将数据库查询限制为仅在自上次按键后经过500毫秒时。

我确信有更好的方法可以做到这一点。 这段代码“适合我”。 批评者表示赞赏。
