How to Retrive single data from sqldatasource control

hi,

i need to code for retrieving single data from sqldatasource control. i need the full set of coding

connecting
retrieving data in text box
editing data to the table
updating data to the table
deleting data to the table

i want to fetch "single field data"

any one who know the code please post reply or send it to my mail senthilonline_foryou@.rediffmail.comI suggest that you use a stored procedure like this (assuming ID is an identity index column, with a data row NAME VARCHAR(50) in Table Fred)

CREATE PROCEDURE dbo.uspGetFred
(
@.ID INT,
@.NAME VARCHAR(50) OUTPUT
)
SET NOCOUNT ON
SELECT NAME FROM Fred WHERE ID = @.ID
GO

The VB code below retrieves NAME into aName fpor a given value of iID
CONST DBCONNECT As String = "Your Connect String"

Dim sName As String = ""
Dim xSqlConnection As SqlConnection = New SqlConnection(DBCONNECT )
Dim xSqlCommand As SqlCommand = New SqlCommand("uspGetFred", xSqlConnection)
Try
xSqlCommand.CommandType = CommandType.StoredProcedure
xSqlCommand.Parameters.Add("@.ID", SqlDbType.Int)
xSqlCommand.Parameters("@.ID").Value = CType(iId, Integer)
xSqlCommand.Parameters.Add("@.NAME", SqlDbType.VarChar, 50)
xSqlCommand.Parameters("@.NAME").Direction = ParameterDirection.Output
xSqlCommand.Connection.Open()
xSqlCommand.ExecuteNonQuery()
sName = xSqlCommand.Parameters("@.NAME").Value
Catch ex As Exception
' Handle your error here!
Finally
xSqlCommand.Connection.Close()
xSqlCommand.Dispose()
xSqlConnection.Dispose()
End Try

HTH!
