    NET Framework ใน Version 2.0 ขึ้นไป โดยมีประโยชน์ในการสร้าง Connection เชื่อมต่อกับฐานข้อมูล SQL Server (2000,2005,2008) โดยที่เราไม่ต้องทำการ Import System.

    One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").While the events fired by the Data Sources are similar, the parameters passed by the various Data Sources are different. The e parameter passed to the Row Updating event on the Grid View gives you access to the data in the row being updated (including the data originally retrieved and the current data), simplifying your validation code.In many ways, the parameters passed to the Sql Data Source's events give you more control than any of the other Data Sources. Using the Data View event also means that you're not tied to any particular Data Source.For instance, in the SQLData Source, the e parameter gives you access to the Command object being used and all of its properties. Select Command Type = Sql Data Source Command Type. If you decide to switch from SQL to Entity Framework, for instance, you won't have to change any code if you've used the Data View's events.The SQLData Source's *ing events are the best place to set values in any parameters that your SQL statements are using. Tailoring Queries In the Selecting event, additional options are available through the Select Arguments object that's available through the e parameter's Arguments property.
