Ajax切换按钮扩展程序不工作

本文关键字：程序 工作 扩展 按钮 Ajax | 更新日期: 2023-09-27 18:12:52

<asp:CheckBox ID="CheckBox1" OnCheckedChanged="CheckBox1_CheckedChanged" runat="server" Text="Toggle Visibility" AutoPostBack="true"/>

和Ajax切换按钮扩展器:

<ajaxToolkit:ToggleButtonExtender ID="Ext1" CheckedImageAlternateText="View" TargetControlID="CheckBox1" runat="server" CheckedImageUrl="~/Images/Others/view.png" UncheckedImageAlternateText="Hide" UncheckedImageUrl="~/Images/Others/hide.png" ImageWidth="32" ImageHeight="24" ></ajaxToolkit:ToggleButtonExtender>

但它不起作用。页面正在加载，但是带有默认的复选框。

感谢您的帮助
