}

set

...{

ViewState["Offset"] = value;

}

protected void Page_Load(object sender, EventArgs e)

...{

ScriptManager1.RegisterAsyncPostBackControl(DecrementButton);

ScriptManager1.RegisterAsyncPostBackControl(IncrementButton);

}

protected void MasterButton_Click(object sender, EventArgs e)

...{

switch (((Control)sender).ID)

...{

case "IncrementButton":

this.Offset = this.Offset + 1;

break;

case "DecrementButton":

this.Offset = this.Offset - 1;

break;

}

((UpdatePanel)ContentPlaceHolder1.FindControl("UpdatePanel1")).Update();

Calendar cal = ((Calendar)ContentPlaceHolder1.FindControl("Calendar1"));

DateTime newDateTime = DateTime.Today.Add(new TimeSpan(Offset, 0, 0, 0));

cal.SelectedDate = newDateTime;

}

ContentPage ASPX页面代码：

<%...@ Page Language="C#" MasterPageFile="~/AjaxMaster.Master" AutoEventWireup="true" CodeBehind="Content.aspx.cs" Inherits="UpdatepanelInManage.Content" Title="Untitled Page" %>

<%...@ MasterType VirtualPath="AjaxMaster.Master" %>

Content Page<br />

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<asp:Calendar ID="Calendar1" runat="server" OnSelectionChanged="Calendar1_SelectionChanged"></asp:Calendar>

</ContentTemplate>

</asp:UpdatePanel>

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

namespace UpdatepanelInManage

...{

public partial class Content : System.Web.UI.Page

...{

protected void Page_Load(object sender, EventArgs e)

...{

DateTime newDateTime =

DateTime.Today.Add(new TimeSpan(Master.Offset, 0, 0, 0));

Calendar1.SelectedDate = newDateTime;

}

protected void Calendar1_SelectionChanged(object sender, EventArgs e)

...{

DateTime selectedDate = Calendar1.SelectedDate;

//添加@ MasterType标记到页面中，以便可以作为强类型属性引用Master Page页面的Offset属性

// <%@ MasterType VirtualPath="AjaxMaster.Master" %>

Master.Offset = ((TimeSpan)Calendar1.SelectedDate.Subtract(DateTime.Today)).Days;
