                {…}
                Note you can replace "DynamicPopulateMethod" with a naming of your choice, but the return
                type and parameter name and type must exactly match, including case.
代码[dai ma]示意:
<ajaxToolkit:DynamicPopulateExtender ID="dp" runat="server"
    TargetControlID="Panel1"

                (2)过滤[guo lv]条件[tiao jian]也可以是Custom的组合[zu he] FilterType="Custom, Numbers"
                (3)ValidChars="+-=/*()." Custom要定义这样的有效[you xiao]字[you xiao zi]符[you xiao zi fu]串
                (4) 其实这是个鸡肋:你可以输入[shu ru]中文[zhong wen],聊胜于无,忍了
示意代码[dai ma]:
<ajaxToolkit:FilteredTextBoxExtender ID="ftbe" runat="server"

   功能:Xp的关机效果,后面全部灰掉,很多邮箱的删除[shan chu]对话框[dui hua kuang]都着种效果
   细节: (1)本质上讲这是一个对话框[dui hua kuang]模版,比ConfirmButton有意义有更强的扩展[kuo zhan]性!
                (2)从下面的代码[dai ma]中我们发现 点OK的时候可以调用[tiao yong]后台[hou tai]方法[fang fa]
                (3)同时可以执行[zhi hang]一段脚本[jiao ben]
代码[dai ma]示意:

 21.ReorderList  

   功能:这个控件的炫酷程度仅次于Animation ,可以动态[dong tai]移动数据[shu ju]
   细节: (1)绑定[bang ding]数据[shu ju],拖动[tuo dong]数据[shu ju]之后数据[shu ju]将被更新到绑定[bang ding]源
                (2)它不是已有控件的扩展[kuo zhan]是全新的服务器[fu wu qi]端控件,只是它对Ajax行为是敏感的
                (3)重排的实现有两种方式:CallBack PostBack 前者的发生在页面上是没有PostBack的(也就是没有刷新[shua xin]页面)
                (4) 而数据[shu ju]添加或者编辑的时候就必须要使用PostBack来同步[tong bu]服务器[fu wu qi]端的数据[shu ju]状态[zhuang tai]
                (5)PostbackOnReorder就是针对两种策略进行选[hang xuan]择
                (6)可以扩展[kuo zhan]的很多,三言两语难以说尽给出基本框架[kuang jia]吧,回头再说
代码[dai ma]示意:
   <ajaxToolkit:ReorderList ID="ReorderList1" runat="server"
    DataSourceID="ObjectDataSource1"

      <InsertItemTemplate></InsertItemTemplate>
</ajaxToolkit:ReorderList>

 22.ResizableControl  

   功能:就像设计状态[zhuang tai]一样可以拖动[tuo dong]修改[xiu gai]大小,可是有什么实际的意义么,放大字体[zi ti]?没有想到
   细节: (1)HandleCssClass – The name of the CSS class to apply to the resize handle 这个属性[shu xing]必须要有!
  代码[dai ma]示意:
<ajaxToolkit:ResizableControlExtender ID="RCE" runat="server"
    TargetControlID="PanelImage"
    HandleCssClass="handleImage"
    ResizableCssClass="resizingImage"
    MinimumWidth="50"

    MaximumWidth="260"
    MaximumHeight="130"
    OnClientResize="OnClientResizeImage"
    HandleOffsetX="3"
    HandleOffsetY="3" />

 23.RoundedCorners  

   功能:控件圆角[yuan jiao] 纯粹是控制[kong zhi]外观的了,什么时候审美疲劳了还要改,呵呵
   细节: (1)还有一个非常非常坑人的地方:你必须要设置[she zhi] CssClass="roundedPanel"要不然不起作用[zuo yong]
                (2) Radius设置[she zhi]弧度,默认[mo ren]是5
                (3)好象只适用于[yong yu]容器
代码[dai ma]示意:
              <ajaxToolkit:RoundedCornersExtender ID="rce" runat="server"     TargetControlID="Panel1"     Radius="6" />

 24.Slider  

   功能:实现WinForm中的Slider控件效果
   细节: (1)修改[xiu gai]文本[wen ben]框的值也可以影响Slider的状态[zhuang tai]!这个反馈还是有用的!

    <cc1:SliderExtender ID="SliderExtender2" runat="server"
                                BehaviorID="Slider2"
                                TargetControlID="Slider2"
                                BoundControlID="TextBox1"
                                Orientation="Horizontal"
                                EnableHandleAnimation="true"
                                 Minimum="0"
                                Maximum="100"
                                />

 25.TextBoxWatermark  

   功能:文本[wen ben]水印
   细节: 没有什么说的看代码[dai ma]—>
代码[dai ma]示意:
    <asp:TextBox ID="TextBox1" CssClass="unwatermarked" Width="150" runat="server"></asp:TextBox>
            <cc1:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" runat="server" TargetControlID="TextBox1" WatermarkText="请输入[shu ru]用户[yong hu]名[yong hu ming]" WatermarkCssClass="watermarked" />

 26.UpdatePanelAnimation  

   功能:更新动画[dong hua]效果
   细节:代码[dai ma]结构[jie gou]简单但是要说的东西很多,回头再说写专题吧
代码[dai ma]示意:
  <ajaxToolkit:UpdatePanelAnimationExtender ID="ae"
  runat="server" TargetControlID="up">
     <Animations>
        <OnUpdating>  </OnUpdating>
        <OnUpdated>  </OnUpdated>
    </Animations>
</ajaxToolkit:UpdatePanelAnimationExtender>

 27.ToggleButton  

   功能:就是把一个CheckBox的逻辑应用[ying yong]到一个按钮上,于是就有了双态按钮这么个玩意,有点意思啊
   闲言少叙,看代码[dai ma]:
<asp:CheckBox ID="CheckBox1" Checked="true" Text="I like ASP.NET" runat="server"/>
    <cc1:ToggleButtonExtender ID="ToggleButtonExtender1" runat="server" TargetControlID="CheckBox1" ImageWidth="19"
     ImageHeight="19" UncheckedImageUrl="Image/down.gif" CheckedImageUrl="Image/up.gif" CheckedImageAlternateText="Check"
     UncheckedImageAlternateText="UnCheck" />

 28.ValidatorCallout  

   功能:Windows系统[xi tong]中最常见的气泡提示[ti shi],比如你磁盘[ci pan]空间[kong jian]不足的时候……
   细节: 是对数据[shu ju]验证[yan zheng]控件的扩展[kuo zhan],比较新鲜
代码[dai ma]示意:
<asp:RequiredFieldValidator runat="server" ID="NReq" ControlToValidate="NameTextBox" Display="None" ErrorMessage="<b>Required Field Missing</b><br />A name is required." />
        <asp:RequiredFieldValidator runat="server" ID="PNReq" ControlToValidate="PhoneNumberTextBox" Display="None" ErrorMessage="<b>Required Field Missing</b><br />A phone number is required.<div style=’margin-top:5px;padding:5px;border:1px solid #e9e9e9;background-color:white;’><b>Other Options:</b><br /><a href=’javascript:alert(&quot;not implemented but you get the idea;)&quot;);’>Extract from Profile</a></div>" />
