AjaxControlToolKit之DragPanelExtender用法

1、将控件ToolkitScriptManager拖至页面中...
2、定义3个Panel，用于实现窗体拖动效果，代码如下：

<form id="form1" runat="server">
3

<div>
4

<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
5

</cc1:ToolkitScriptManager>
6

</div>
8

<div style=" 292px; height: 318px">
9

<asp:Panel ID="Panel3" runat="server" Height="50px" Width="125px">
10

<asp:Panel ID="Panel1" runat="server" Height="27px" Width="292px" BackColor="ActiveBorder" BorderWidth="1px">
11

鼠标拖动区域</asp:Panel>
12

<asp:Panel ID="Panel2" runat="server" Height="274px" Width="291px" Style="overflow: scroll" BorderColor="Black" BorderWidth="1px">
13

14

</asp:Panel>
15

</div>
16

<cc1:DragPanelExtender ID="DragPanelExtender1" runat="server" TargetControlID="Panel3">
17

</cc1:DragPanelExtender>
18

</form>

</body>

并且将DragPanelExtender控件拖至页面中，使其TargetControlID="Panel3"，指定要拖动的区域的Panel，如本例中的Panel3.
