VB.net ComboBox自动下拉输入 [英] VB.net ComboBox auto drop down on input

问题描述

我想创建一个ComboBox，它会根据输入自动删除包含字母的字词。我的下拉菜单是下拉框，所以组合框有一个输入字段。

I want to create a ComboBox that automaitcally drops down the words containing the letter based on the input. My dropdownstyle is dropdown so the combobox has an input field.

例如，我将输入字母A或a我想要ComboBox自动下拉包含字母A或a。 ComboBox的内容是由我自己手动设置的。

For example i would input the letter A or a I want the ComboBox to automatically dropdown the words which contains the letter A or a. The contents of the ComboBox are being set by myself manually.

这是可能吗？提前感谢。

Is this possible? Thanks in advance.

推荐答案

您必须设置这些

AutoCompleteMode: SuggestAppend
AutoCompleteSource: ListItems
DropDownStyle: DropDown

$ b b

假设您的组合有这些项目，那么您必须将它们添加到autocompletecustomsource

Suppose your combo has these items then you have to add them to the autocompletecustomsource also

ComboBox1.Items.Add("10")
ComboBox1.Items.Add("92")
ComboBox1.Items.Add("9000")
ComboBox1.Items.Add("9001")

ComboBox1.AutoCompleteCustomSource.Add("10")
ComboBox1.AutoCompleteCustomSource.Add("92")
ComboBox1.AutoCompleteCustomSource.Add("9000")
ComboBox1.AutoCompleteCustomSource.Add("9001")

ComboBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
