asp.net实例代码之显示数据在不同的控件

发布时间:2020-03-02编辑:脚本学堂
本文分享一个asp.net的例子,用于在不同的控件中显示数据,有需要的朋友参考下吧。

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
