Rowupdating get datakey

En este articulo veremos las algunas formas de lograrlo y como difieren las técnicas que se puede aplicarse.Temas que se tratar: 1- Seleccionar una Row 2-Uso de Data Key Names y Data Keys a- Data Key Names con campos Múltiples Para todos los casos planteados partiremos del mismo gridview, el cual se ira modificando para agregarle opciones y ver los distintos temas.

Now you can ask questions directly to me on my new site ASPForums. También se dispone de distintos tipos de representación visual, como ser un Link, Button o Image.Para este caso usaremos un comando del tipo Image, por lo tanto se deberá definir la propiedad “Select Image Url”.Para este caso en particular se agregara solo la opción de selección.Mediante las flechas laterales se puede posicionar el comando.In this example I will give you a complete solution on “How to operate Check Box List in Grid View Edit Mode“ CREATE TABLE [dbo].[Brand]( [ID] [bigint] NOT NULL, [Name] [varchar](max) NOT NULL, CONSTRAINT [PK_Brand] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[Product]( [ID] [bigint] NOT NULL, [Name] [varchar](max) NULL, [Description] [varchar](max) NULL, [Brand ID] [bigint] NULL, CONSTRAINT [PK_Product_2] PRIMARY KEY CLUSTERED ( [ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] INSERT INTO Brand Values(1,'Kohinoor') INSERT INTO Brand Values(2,'Proctor & Gamble') INSERT INTO Brand Values(3,'Telenor') INSERT INTO Brand Values(4,'Unilever') INSERT INTO PRODUCT VALUES(1,'Lux Beauty Soap','Product of Unilever',4) INSERT INTO PRODUCT VALUES(2,'Tibbet Pomed','Winter Product',1) INSERT INTO PRODUCT VALUES(3,'Data SIM','Subscriber Identity Module',3) INSERT INTO PRODUCT VALUES(4,'Nippon','Color Television',1) Note: If you look at the Grid View events you will get onrowdatabound, onrowupdating, onrowediting, onrowcancelingedit events. Like onrowdatabound event will fire when Grid View Data Bind() method was called, onrowediting event will fire when user click on Edit link, onrowupdating event will fire when user click on Update link & onrowcancelingedit will fire when user click on Cancel link.

Keep in mind in every event we need to rebind the Grid View Note: Don’t forget to add “System.

We define a connection in the web.config file and give a name to the connection string.

Now we access this connection string on the page so we can open a connection with the relation database. The first one accesses the connection string and the other is for the SQL connection.

Open Visual Studio 2008 and create a new Web Application.

This example won’t hook into a database, but we will create a class to mock a table and retrieve data from it instead. This enables you to not display the ID to the user, yet still being able to retrieve it.

Here we can update Name, Emp_Code and Emp_Age fields depending on the Id field of the "EMPLOYEE" table.
