AjaxPanel自定义控件实现页面无刷新数据交互

 

(一) . 简要

          AjaxPanel, 一个自定义控件, 只要在页面中将AjaxPanel作为父控件, 则它内部的控件在运行时无刷新. 

          做了个程序试了一下果然比较Cool !  下面介绍一下具体配置, 配置也比较简单.

(二). 运行示例图

(三). 配置

     1. 把 AjaxPanel 添加到工具箱中. 步骤如下:

  2. 在Web.Config文件的: <configuration> 节,添加如下配置:

1 <configSections>2      <section name="magicAjax" type="MagicAjax.Configuration.MagicAjaxSectionHandler, MagicAjax"/>3      </configSections>4      <magicAjax outputCompareMode="HashCode" tracing="false">5         <pageStore mode="NoStore" unloadStoredPage="false" cacheTimeout="5" maxConcurrentPages="5" maxPagesLimitAlert="false"/>6      </magicAjax>7  <configSections>
<system.web>2         <httpModules>3             <add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax"/>4         </httpModules>5 <system.web>

(四). 做了上面几步配置后, 下面就可以使用了, 示例代码也非常简单, 具体如下:

   1.前台页面文件 Magicajax.aspx 代码如下:

 1 <body> 2     <form id="form1" runat="server"> 3     <div> 4         <ajax:AjaxPanel ID="AjaxPanel1" runat="server" FontBold="True"> 5             <asp:Panel ID="Panel1" runat="server" FontSize="XX-Large" Height="45px" Width="273px"> 6                 AjaxPanel example</asp:Panel> 7             <br /> 8             <asp:Button ID="Button1" runat="server" BackColor="#FFC080" Height="26px" OnClick="Button1_Click" 9                 Text="CreateData" Width="85px" />10             &nbsp;11             <asp:Button ID="Button2" runat="server" BackColor="#FFC080" Height="26px" Text="ClearData"12                 Width="73px" /><br />13             <br />14             <asp:GridView ID="GridView1" runat="server" BackColor="White" BorderColor="#E7E7FF"15                 BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Horizontal">16                 <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />17                 <RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />18                 <SelectedRowStyle BackColor="#738A9C" FontBold="True" ForeColor="#F7F7F7" />19                 <PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />20                 <HeaderStyle BackColor="#4A3C8C" FontBold="True" ForeColor="#F7F7F7" />21                 <AlternatingRowStyle BackColor="#F7F7F7" />22             </asp:GridView>23         </ajax:AjaxPanel>24     25     </div>26     </form>27 </body>

  2.后台页面文件 Magicajax.aspx.cs 代码如下:

 1 public partial class _Default : System.Web.UI.Page  2 { 3     protected void Page_Load(object sender, EventArgs e) 4     { 5  6     } 7    private DataTable CreateStructure() 8    { 9         DataTable dt = new DataTable();10         dt.Columns.Add(new DataColumn("CategoryID"typeof(int)));11         dt.Columns.Add(new DataColumn("CategoryName"typeof(string)));12         dt.Columns.Add(new DataColumn("Price"typeof(int)));      13         return dt;14    }15    public DataSet CreateData()16    {17      DataSet ds = new DataSet();18      DataTable dt = this.CreateStructure();19 20      DataRow drNew = dt.NewRow();      21      drNew = dt.NewRow();22      drNew["CategoryID"= 1;23      drNew["CategoryName"= "Apple";24      drNew["Price"= 2;25      dt.Rows.Add(drNew);26 27      drNew = dt.NewRow();28      drNew["CategoryID"= 2;29      drNew["CategoryName"= "Banana";30      drNew["Price"= 3;31      dt.Rows.Add(drNew);32 33      drNew = dt.NewRow();34      drNew["CategoryID"= 3;35      drNew["CategoryName"= "Orange";36      drNew["Price"= 1;37      dt.Rows.Add(drNew);38 39      drNew = dt.NewRow();40      drNew["CategoryID"= 4;41      drNew["CategoryName"= "Radish";42      drNew["Price"= 2;43      dt.Rows.Add(drNew);44 45      drNew = dt.NewRow();46      drNew["CategoryID"= 5;47      drNew["CategoryName"= "Pen";48      drNew["Price"= 3;49      dt.Rows.Add(drNew);50 51      drNew = dt.NewRow();52      drNew["CategoryID"= 6;53      drNew["CategoryName"= "Pencil";54      drNew["Price"= 7;55      dt.Rows.Add(drNew);56 57      drNew = dt.NewRow();58      drNew["CategoryID"= 7;59      drNew["CategoryName"= "Ruler";60      drNew["Price"= 3;61      dt.Rows.Add(drNew);62 63      drNew = dt.NewRow();64      drNew["CategoryID"= 8;65      drNew["CategoryName"= "Eraser";66      drNew["Price"= 5;67      dt.Rows.Add(drNew);68 69      ds.Tables.Add( dt );70      return ds;71    }72    protected void Button1_Click(object sender, EventArgs e)73    {74       this.GridView1.DataSource = this.CreateData();75       this.DataBind();76    }77 }
