注釈

Edit DataGrid Cancel Updateクラスを使用して、グリッド内の各データ行の、、およびの各ボタンを含むコントロールの特別な列を作成します。 EditCommandColumnUse the EditCommandColumn class to create a special column for the DataGrid control that contains the Edit, Update, and Cancel buttons for each data row in the grid. これらのボタンを使用すると、 DataGridコントロールの行の値を編集できます。These buttons allow you to edit the values of a row in the DataGrid control.

行が選択さEditれていない場合は、 EditCommandColumn DataGridコントロールの各データ行に対応するボタンがオブジェクトに表示されます。If no row is selected, an Edit button displays in the EditCommandColumn object for each data row in the DataGrid control. Cancel Update Edit EditCommand項目のボタンがクリックされると、イベントが発生し、ボタンがボタンとボタンに置き換えられます。EditWhen the Edit button for an item is clicked, the EditCommand event is raised and the Edit button is replaced with the Update and Cancel buttons. EditCommandイベントを処理するコードを指定する必要があります。You need to provide code to handle the EditCommand event. 一般的なイベントハンドラーは、 EditItemIndexプロパティを選択された行に設定し、データをDataGridコントロールに再バインドします。A typical event handler sets the EditItemIndex property to the selected row, and then rebinds the data to the DataGrid control.

注意

CancelTextEditText、およびUpdateTextの各プロパティの値を指定する必要があります。You must provide values for the CancelText, EditText, and UpdateText properties. それ以外の場合、関連付けられてEditCommandColumnいるボタンはに表示されません。Otherwise, the associated buttons will not appear in the EditCommandColumn.

のボタンは、 EditCommandColumn ButtonTypeプロパティを設定することにより、ハイパーリンクまたはプッシュボタンとして表示するように設定できます。The buttons in the EditCommandColumn can be set to display as hyperlinks or push buttons by setting the ButtonType property.

またはUpdate CancelボタンをクリックするUpdateCommandCancelCommand 、イベントまたはイベントがそれぞれ発生します。Clicking the Update or Cancel button raises the UpdateCommand or CancelCommand event, respectively. これらのイベントを処理するコードを指定する必要があります。You need to provide code to handle these events.

UpdateCommandイベントの一般的なハンドラーによってデータが更新さEditItemIndexれ、 -1プロパティが (項目の選択を解除するために) に設定DataGridされ、データがコントロールに再バインドされます。A typical handler for the UpdateCommand event updates the data, sets the EditItemIndex property to -1 (to deselect the item), and then rebinds the data to the DataGrid control.

CancelCommandイベントの一般的なハンドラーは、 EditItemIndexプロパティを ( -1項目の選択を解除するために) に設定し、データDataGridをコントロールに再バインドします。A typical handler for the CancelCommand event sets the EditItemIndex property to -1 (to deselect the item), and then rebinds the data to the DataGrid control.

注意事項

オブジェクトEditCommandColumnを使用して、悪意のあるクライアントスクリプトを含む可能性のあるユーザー入力を表示できます。The EditCommandColumn object can be used to display user input, which might include malicious client script. アプリケーションに表示する前に、実行可能スクリプト、SQL ステートメント、またはその他のコードに対してクライアントから送信された情報を確認してください。Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. DataGridコントロールに入力テキストを表示する前に、検証コントロールを使用してユーザー入力を検証することができます。You can use validation controls to verify user input before displaying the input text in a DataGrid control. ASP.NET には、ユーザー入力でスクリプトと HTML をブロックする入力要求の検証機能が用意されています。ASP.NET provides an input request validation feature to block script and HTML in user input. 詳細については、「標準コントロールのセキュリティ保護」を参照してください。文字列に HTML エンコーディングを適用し、 ASP.NET Web ページでユーザー入力を検証することにより、Web アプリケーションのスクリプト攻略を防止します。For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Validating User Input in ASP.NET Web Pages.

既定では、 Update EditCommandColumnコントロールのボタンがクリックされると、ページの検証が実行されます。By default, page validation is performed when an Update button in the EditCommandColumn control is clicked. ページの検証では、ページ上の検証コントロールに関連付けられている入力コントロールが、検証コントロールによって指定された検証規則に合格するかどうかを判断します。Page validation determines whether the input controls that are associated with a validation control on the page all pass the validation rules that are specified by the validation control. ページの検証が行われないようにCausesValidationするにfalseは、プロパティをに設定します。To prevent page validation from occurring, set the CausesValidation property to false.
