创建服务器端控件，该控件映射到 <input type=checkbox> HTML 元素并允许您创建使用户可以选择 true 或 false 状态的复选框控件。

<input
Type="Checkbox"
EnableViewState="False|True"
Id="string"
Visible="False|True"
OnDataBinding="OnDataBinding event handler"
OnDisposed="OnDisposed event handler"
OnInit="OnInit event handler"
OnLoad="OnLoad event handler"
OnPreRender="OnPreRender event handler"
OnServerChange="OnServerChange event handler"
OnUnload="OnUnload event handler"
runat="server"

备注
示例
下面的示例演示如何创建 HtmlInputCheckBox 控件来允许用户选择 true 或 false 状态。当用户单击页上包含的输入按钮时，Button1_Click 事件处理程序确定是否选中了 HtmlInputCheckBox 控件。然后，它在 <span> 控件中显示一个消息。请注意，即使此例中在默认情况下将选中的值设置为 true，用户仍然需要单击 Button1 以显示该文本。
