Edit(CurrencyManager, Int32, Rectangle, Boolean)

準備儲存格以進行編輯作業。

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

protected internal virtual void Edit (System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Rectangle bounds, bool readOnly);

abstract member Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool -> unit
override this.Edit : System.Windows.Forms.CurrencyManager * int * System.Drawing.Rectangle * bool -> unit

Protected Friend Overridable Sub Edit (source As CurrencyManager, rowNum As Integer, bounds As Rectangle, readOnly As Boolean)

參數

source: CurrencyManager

CurrencyManager 的 DataGridColumnStyle。

rowNum: Int32

要編輯的資料列編號。

bounds: Rectangle

控制項位置所在的周框 Rectangle。

readOnly: Boolean

數值，指出資料行是否唯讀。如果該值為唯讀，則為 true，否則為 false。

備註

一般而言，方法會將 Edit 控制項放在要編輯之儲存格位置的方格上。
