python实现在不同控件中显示数据的例子,代码如下:
复制代码 代码示例:
<%@ Page Language=VB Debug=true %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OLEDB" %>
<script runat=server>
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
If Not IsPostBack Then
Dim DBConn as OleDbConnection
Dim DBCommand As OleDbDataAdapter
Dim DSPageData as New DataSet
DBConn = New OleDbConnection( _
"PROVIDER=Microsoft.Jet.OLEDB.4.0;" _
& "DATA SOURCE=" _
& Server.MapPath("EmployeeDatabase.mdb;"))
DBCommand = New OleDbDataAdapter _
("Select LastName & ', ' & FirstName " _
& "as EmpName, ID " _
& "From Employee " _
& "Order By LastName, FirstName", DBConn)
DBCommand.Fill(DSPageData, _
"EmployeeNames")
DBCommand = New OleDbDataAdapter _
("Select * from Employee", DBConn)
DBCommand.Fill(DSPageData, _
"EmployeesAll")
DBCommand = New OleDbDataAdapter _
("Select LastName from Employee", DBConn)
DBCommand.Fill(DSPageData, _
"Emp3")
ddlEmps.DataSource = _
DSPageData.Tables("EmployeeNames").DefaultView
ddlEmps.DataBind()
dgEmps2.DataSource = _
DSPageData.Tables("EmployeesAll").DefaultView
dgEmps2.DataBind()
dgEmps3.DataSource = _
DSPageData.Tables("Emp3").DefaultView
dgEmps3.DataBind()
End If
End Sub
