protected:
 bool ProcessRightKey(System::Windows::Forms::Keys keyData);
protected bool ProcessRightKey (System.Windows.Forms.Keys keyData);
member this.ProcessRightKey : System.Windows.Forms.Keys -> bool
Protected Function ProcessRightKey (keyData As Keys) As Boolean

Parámetros

keyData
Keys

Combinación bit a bit de valores de Keys que representa las teclas que se van a procesar.A bitwise combination of Keys values that represents the key or keys to process.

Devoluciones

true si se procesó la tecla; en caso contrario, false.true if the key was processed; otherwise, false.

Excepciones

La tecla FLECHA DERECHA provocaría que el control accediese al modo de edición, pero la propiedad EditType de la nueva celda actual no indica una clase derivada de Control e implementa IDataGridViewEditingControl.The RIGHT ARROW key would cause the control to enter edit mode, but the EditType property of the new current cell does not indicate a class that derives from Control and implements IDataGridViewEditingControl.

Esta acción podría confirmar un valor de celda o provocar el acceso al modo de edición, pero un error en el origen de datos impide la acción y no hay ningún controlador para el evento DataError o el controlador estableció la propiedad ThrowException en true.This action would commit a cell value or enter edit mode, but an error in the data source prevents the action and either there is no handler for the DataError event or the handler has set the ThrowException property to true.

Ejemplos

En el ejemplo de código siguiente se muestra cómo cambiar el comportamiento de la tecla entrar en una subclase DataGridView invalidando los métodos ProcessDataGridViewKey y ProcessDialogKey.The following code example demonstrates how to change the behavior of the ENTER key in a DataGridView subclass by overriding the ProcessDataGridViewKey and ProcessDialogKey methods. En el ejemplo, la tecla entrar tiene el mismo comportamiento que la tecla flecha derecha, lo que facilita que un usuario edite varias celdas en una sola fila de datos.In the example, the ENTER key has the same behavior as the RIGHT ARROW key, making it easier for a user to edit multiple cells in a single row of data.
