次のコード例は、複数の項目を選択できるようにする @no__t 0 を示しています。The following code example demonstrates a ListView that allows multiple items to be selected. この例では、HideSelection および HeaderStyle プロパティを設定する方法を示します。The example demonstrates setting the HideSelection and HeaderStyle properties. また、ColumnHeader.TextColumnHeader.TextAlignColumnHeader.Width の各プロパティも示しています。It also demonstrates the ColumnHeader.Text, ColumnHeader.TextAlign and ColumnHeader.Width properties. この例を実行するには、次のコードを ListView1 という名前の @no__t 0 オブジェクトと、TextBox1 という名前の @no__t) を含むフォームに貼り付けます。To run this example, paste the following code into a form that contains a ListView object named ListView1 and a TextBox named TextBox1. フォームのコンストラクターまたは Load イベントハンドラーから InitializeListView メソッドを呼び出します。Call the InitializeListView method from the form's constructor or Load event handler.

// This method adds two columns to the ListView, setting the Text 
// and TextAlign, and Width properties of each ColumnHeader.  The 
// HeaderStyle property is set to NonClickable since the ColumnClick 
// event is not handled.  Finally the method adds ListViewItems and 
// SubItems to each column.

注釈

@No__t-0 プロパティを使用すると、ListView コントロールの View プロパティが Details に設定されている場合に表示する列ヘッダーの種類を指定できます。また、ListView コントロールに ListView.ColumnHeaderCollection で指定した @no__t 5 個のオブジェクトが指定されています。The HeaderStyle property allows you to specify the type of column headers to display when the View property of the ListView control is set to Details and the ListView control has ColumnHeader objects specified in the ListView.ColumnHeaderCollection. ColumnHeader オブジェクトは、ListView コントロールに表示される列を定義します。ColumnHeader objects define the columns that are displayed in the ListView control. 各列は、ListView の各項目のサブ項目情報を表示するために使用されます。Each column is used to display subitem information for each item in the ListView.

@No__t-0 プロパティを使用すると、列ヘッダーを表示するかどうかを指定できます。また、表示される場合は、クリック可能なボタンとして機能するかどうかを指定できます。The HeaderStyle property allows you to specify whether the column headers are visible or, if they are visible, whether they will function as clickable buttons. @No__t-0 プロパティが ColumnHeaderStyle.None に設定されている場合、ListView コントロールの項目とサブ項目は引き続き列に配置されますが、列ヘッダーは表示されません。If the HeaderStyle property is set to ColumnHeaderStyle.None, the column headers are not displayed, although the items and subitems of the ListView control are still arranged in columns. @No__t-0 プロパティが ColumnHeaderStyle.Clickable に設定されている場合、列ヘッダーは、ユーザーがクリックして操作を実行できるボタンのように機能します。たとえば、クリックした列の項目をキーとして使用して、ListView コントロールの項目を並べ替えることができます。If the HeaderStyle property is set to ColumnHeaderStyle.Clickable, the column headers act like buttons that users can click to carry out an action, such as sorting the items in the ListView control using the items in the clicked column as a key. この動作は、ColumnClick イベントのハンドラーで実装できます。You can implement this behavior in a handler for the ColumnClick event. @No__t-0 プロパティが ColumnHeaderStyle.Nonclickable に設定されている場合、列ヘッダーは表示されますが、クリックすることはできません。If the HeaderStyle property is set to ColumnHeaderStyle.Nonclickable, the column headers appear, but cannot be clicked.
