何を開発していますか?Web アプリケーションの場合は、jQuery UI を使用してテキスト ボックスのオートコンプリートを実装できます。
$(function() {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$( "#tags" ).autocomplete({
source: availableTags
});
});
WPF を使用している場合は、C# でも同様に実行できます。
public Window1()
{
InitializeComponent();
List<string> source = new List<string>{/*your source of strings*/};
TextBoxName.ItemSource = source;
}
別の方法:
private void Form1_Load(object sender, EventArgs e)
{
// Create the list to use as the custom source.
var source = new AutoCompleteStringCollection();
source.AddRange(new string[]
{
"January",
"February",
"March",
"April",
"May",
"June",
"July",
"August",
"September",
"October",
"November",
"December"
});
// Create and initialize the text box.
var textBox = new TextBox
{
AutoCompleteCustomSource = source,
AutoCompleteMode =
AutoCompleteMode.SuggestAppend,
AutoCompleteSource =
AutoCompleteSource.CustomSource,
Location = new Point(20, 20),
Width = ClientRectangle.Width - 40,
Visible = true
};
// Add the text box to the form.
Controls.Add(textBox);
}
