Ejemplos

Esta sección contiene dos ejemplos de código.This section contains two code examples. En el primer ejemplo de código se muestra cómo insertar datos en una base de datos mediante el SqlDataSource control.The first code example demonstrates how to insert data into a database using the SqlDataSource control. En el segundo ejemplo de código se muestra cómo recuperar datos de Microsoft SQL Server, cómo mostrarlos en un GridView control y cómo utilizar un DetailsView control para ver los detalles de una fila seleccionada en GridView y como un formulario para insertar nuevos registros.The second code example demonstrates how to retrieve data from Microsoft SQL Server, display it in a GridView control, and use a DetailsView control to see details of a selected row in the GridView and as a form to insert new records.

En el ejemplo de código siguiente se muestra cómo insertar datos en una base de datos mediante el SqlDataSource control.The following code example demonstrates how to insert data into a database using the SqlDataSource control. Los datos actuales de la tabla se muestran en el DropDownList control.The current data in the table is displayed in the DropDownList control. Puede agregar nuevos registros escribiendo valores en los TextBox controles y, a continuación, haciendo clic en el botón Insertar .You can add new records by entering values in the TextBox controls, and then clicking the Insert button. Al hacer clic en el botón Insertar , se insertan los valores especificados en la base de datos y DropDownList se actualiza el.When the Insert button is clicked, the specified values are inserted into the database and the DropDownList is refreshed.

En el ejemplo de código siguiente se muestra cómo recuperar datos de SQL Server, cómo mostrarlos en un GridView control y cómo utilizar un DetailsView control para ver los detalles de una fila seleccionada en GridView y como un formulario para insertar nuevos registros.The following code example demonstrates how to retrieve data from SQL Server, display it in a GridView control, and use a DetailsView control to see details of a selected row in the GridView and as a form to insert new records.

Inicialmente, los datos se muestran en el GridView control y la fila seleccionada de GridView también se muestra en el DetailsView control.Initially, the data is displayed in the GridView control and the selected row of the GridView is also displayed in the DetailsView control. Los GridView DetailsView controles y utilizan controles de origen de datos diferentes; el que está asociado a DetailsView tiene las FilterExpression FilterParameters propiedades y, que garantizan que se muestre la fila seleccionada de GridView .The GridView and DetailsView controls use different data source controls; the one that is associated with the DetailsView has the FilterExpression and FilterParameters properties, which ensure that the selected row of the GridView is displayed.

Si hace clic en el botón Insertar generado automáticamente del DetailsView control, DetailsView muestra una interfaz de usuario diferente, que se usa para insertar un nuevo registro.If you click the automatically generated Insert button of the DetailsView control, the DetailsView shows a different user interface, which is used to insert a new record. En el ejemplo se utiliza un procedimiento almacenado para insertar registros y se devuelve la clave principal de la fila insertada.The example uses a stored procedure to insert records and returns the primary key of the inserted row. Si inserta un registro, DetailsView rellena automáticamente la InsertParameters colección con los valores de las columnas enlazadas y llama al Insert método.If you insert a record, the DetailsView automatically populates the InsertParameters collection with values from the bound columns and calls the Insert method. DetailsViewPuede deducir los parámetros correctos de cualquier BoundField objeto y un parámetro para el TemplateField objeto cuando se utiliza la sintaxis de enlace de datos bidireccional ASP.net.The DetailsView can infer the correct parameters from any BoundField object and a parameter for the TemplateField object when the ASP.NET two-way data-binding syntax is used. En este ejemplo, se agrega un parámetro adicional en el OnInserting controlador de eventos para controlar la clave principal devuelta por el procedimiento almacenado.In this example, an additional parameter is added in the OnInserting event handler to handle the primary key that is returned by the stored procedure.

Por último, después de que el control Inserte los datos DetailsView en la base OnInserted de datos, se llama al controlador de eventos para controlar el Inserted evento, se muestra el valor de la clave principal de la fila insertada y se DataBind GridView llama explícitamente al método del control para actualizar los datos.Finally, after data is inserted by the DetailsView control into the database, the OnInserted event handler is called to handle the Inserted event, the value of the primary key of the inserted row is displayed, and the DataBind method of the GridView control is called explicitly to refresh the data.

Como productos de base de datos diferentes usan variedades diferentes de SQL, la sintaxis de la cadena de SQL depende del proveedor de ADO.NET actual que se está usando, identificado por la propiedad ProviderName.Because different database products use different varieties of SQL, the syntax of the SQL string depends on the current ADO.NET provider being used, which is identified by the ProviderName property. Si la cadena de SQL es un comando o consulta parametrizado, el marcador de posición del parámetro también depende del proveedor de ADO.NET que se está usando.If the SQL string is a parameterized query or command, the placeholder of the parameter also depends on the ADO.NET provider being used. Por ejemplo, si el proveedor es System.Data.SqlClient , que es el proveedor predeterminado para la SqlDataSource clase, el marcador de posición del parámetro es '@parameterName' .For example, if the provider is the System.Data.SqlClient, which is the default provider for the SqlDataSource class, the placeholder of the parameter is '@parameterName'. Sin embargo, si el proveedor está establecido en System.Data.Odbc o System.Data.OleDb , el marcador de posición del parámetro es '?' .However, if the provider is set to the System.Data.Odbc or System.Data.OleDb, the placeholder of the parameter is '?'. Para obtener más información sobre los comandos y las consultas SQL parametrizados, vea usar parámetros con el control SqlDataSource.For more information on parameterized SQL queries and commands, see Using Parameters with the SqlDataSource Control.

La InsertCommand propiedad puede ser una cadena SQL o el nombre de un procedimiento almacenado, si el origen de datos admite procedimientos almacenados.The InsertCommand property can be an SQL string or the name of a stored procedure, if the data source supports stored procedures.

El valor de la InsertCommand propiedad se almacena en el estado de vista.The value of the InsertCommand property is stored in view state.
