.net2.0的页面传值

推荐使用,可踌页面传值或对象.关于其他页面传值方式,

开始正题:page1.aspx前台代码

< html xmlns = " http://www.w3.org/1999/xhtml " >
< head runat = " server " >
     < title > first Page </ title >
</ head >
< body >
     < form id = " form1 "  runat = " server " >
         < div >
            输入你的名字: < br  />
             < asp:TextBox ID = " TextBox1 "  runat = " server " >

             </ asp:TextBox >
             < p >
                选择一个日期 < br  />
                 < asp:Calendar ID = " Calendar1 "  runat = " server "  BackColor = " White "  BorderColor = " Black "  BorderStyle = " Solid "  CellSpacing = " 1 "  Font - Names = " Verdana "  Font - Size = " 9pt "  ForeColor = " Black "  Height = " 250px "  NextPrevFormat = " ShortMonth "  Width = " 330px " >
                     < SelectedDayStyle BackColor = " #333399 "  ForeColor = " White "   />
                     < TodayDayStyle BackColor = " #999999 "  ForeColor = " White "   />
                     < DayStyle BackColor = " #CCCCCC "   />
                     < OtherMonthDayStyle ForeColor = " #999999 "   />
                     < NextPrevStyle Font - Bold = " True "  Font - Size = " 8pt "  ForeColor = " White "   />
                     < DayHeaderStyle Font - Bold = " True "  Font - Size = " 8pt "  ForeColor = " #333333 "  Height = " 8pt "   />
                     < TitleStyle BackColor = " #333399 "  BorderStyle = " Solid "  Font - Bold = " True "  Font - Size = " 12pt "
                        ForeColor = " White "  Height = " 12pt "   />
                 </ asp:Calendar >
             </ p >
             < br  />
             < asp:Button ID = " Button1 "  runat = " server "  Text = " 提交到当前页 "  OnClick = " Button1_Click "   />
             < asp:Button ID = " Button2 "  runat = " server "  Text = " 提交到page2.aspx "  PostBackUrl = " Page2.aspx "   />
             < p >
                 < asp:Label ID = " Label1 "  runat = " server " ></ asp:Label ></ p >
         </ div >
     </ form >
</ body >
</ html >

后台:page1.aspx.vb

Protected   Sub Button1_Click() Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label1.Text = "Hello " & TextBox1.Text & "<br />" & _
        "日期选择了: " & Calendar1.SelectedDate.ToShortDateString()
    End Sub

第二页page2.aspx.前台放置一个label控件即可,page2.aspx.vb后台代码

Protected   Sub Page_Load() Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        '当上页属性值不为空时
        If Not Page.PreviousPage Is Nothing Then
            Dim p_textbox1 As TextBox = CType(PreviousPage.FindControl("textbox1"), TextBox)
            Dim p_Calendar1 As Calendar = CType(PreviousPage.FindControl("calendar1"), Calendar)
            Label1.Text = "Hello " & p_textbox1.Text & "<br />" & _
             "日期选择了: " & p_Calendar1.SelectedDate.ToShortDateString()
        End If
    End Sub

说明:Page1.aspx上的Button1_Click事件处理页面上服务器控件包含的值
.第二个按钮Button2完全不同。与第一个按钮不同，这个按钮不包含OnClick事件，它使用的是PostBackUrl属性。这个属性带一个字符串值，指向页面要传送到的文件位置。在本例中是Page2.aspx。这说明，现在Page2.aspx接收回送的内容和包含在Page1.aspx控件中的所有值。
要获得从前一个页面传送过来的控件值，只需创建该控件类型的一个实例，并用PreviousPage属性中的FindControl方法填充该实例。赋予FindControl方法的String值是Id值，它用于前一个页面上的服务器控件。赋予了值之后，就可以处理该服务器控件及其值了，就好像它最初位于当前页面上一样。从例子中可以看出，可以从控件中提取Text和SelectedDate属性.
