DataGridTextBoxColumn.Edit メソッド

定義

セルを編集用に準備します。

protected public:
 override void Edit(System::Windows::Forms::CurrencyManager ^ source, int rowNum, System::Drawing::Rectangle bounds, bool readOnly, System::String ^ displayText, bool cellIsVisible);

protected internal override void Edit(System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Rectangle bounds, bool readOnly, string displayText, bool cellIsVisible);
override this.Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool * string * bool -> unit
override this.Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool * string * bool -> unit
Protected Friend Overrides Sub Edit (source As CurrencyManager, rowNum As Integer, bounds As Rectangle, readOnly As Boolean, instantText As String, cellIsVisible As Boolean)
Protected Friend Overrides Sub Edit (source As CurrencyManager, rowNum As Integer, bounds As Rectangle, readOnly As Boolean, displayText As String, cellIsVisible As Boolean)

パラメーター

source
CurrencyManager

列が属するCurrencyManager コントロールのDataGrid

rowNum
Int32

編集中のこの列の行番号。

bounds
Rectangle

コントロールがサイト化される境界 Rectangle

readOnly
Boolean

列が読み取り専用かどうかを示す値。 true 値が読み取り専用の場合。それ以外の場合は false

instantTextdisplayText
String

コントロールに表示するテキスト。

cellIsVisible
Boolean

セルが表示されるかどうかを示す値。 true セルが表示されている場合。それ以外の場合は false

次の例では、 Edit メソッドを使用して、 DataGrid コントロール内のクリックされたセルのテキストを変更します。

public ref class MyGridColumn: public DataGridTextBoxColumn

public:
   void EditCol( CurrencyManager^ cm, int rowNum, Rectangle cellRect, bool readOnly, String^ myString, bool isVisible )

   }

      if ( hi->Type == DataGrid::HitTestType::Cell )

注釈

Editは、グリッド上のTextBox コントロールを編集中のセルの位置に配置します。 このメソッドは、編集操作の開始時に、 DataGrid クラスの BeginEdit メソッドによって呼び出されます。
