Definición

Obtiene el estado del objeto GridViewRow.

public:
 virtual property System::Web::UI::WebControls::DataControlRowState RowState { System::Web::UI::WebControls::DataControlRowState get(); void set(System::Web::UI::WebControls::DataControlRowState value); };
public virtual System.Web.UI.WebControls.DataControlRowState RowState { get; set; }
member this.RowState : System.Web.UI.WebControls.DataControlRowState with get, set
Public Overridable Property RowState As DataControlRowState

Valor de propiedad

DataControlRowState

Combinación bit a bit de los valores de DataControlRowState.

Ejemplos

En el ejemplo siguiente se muestra cómo usar la RowState propiedad para determinar si una fila está en modo de edición o está seleccionada. Si el usuario selecciona una fila diferente mientras el GridView control está en modo de edición, el control sale del GridView modo de edición.

Comentarios

Utilice la RowType propiedad para determinar el estado del GridViewRow objeto. El estado puede ser una combinación bit a bit de los valores de la tabla siguiente:

Valor de estado Descripción
DataControlRowState.Alternate El GridViewRow objeto es una fila alternativa en el GridView control .
DataControlRowState.Edit El GridViewRow objeto está en modo de edición.
DataControlRowState.Normal El GridViewRow objeto está en su estado normal (predeterminado).
DataControlRowState.Selected El GridViewRow objeto está seleccionado.

Esta propiedad se usa normalmente para determinar el estado de una fila antes de realizar una operación.
