HtmlInputButton 服务器控件声明性语法
[本文档仅供预览，在以后的发行版中可能会发生更改。包含的空白主题用作占位符。]
创建服务器端控件，该控件映射到 <input type=button>、<input type=submit> 和 <input type=reset> HTML 元素，并允许您分别创建命令按钮、提交按钮或重置按钮。
<input
Type="Button|Reset|Submit"
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"
OnServerClick="OnServerClick event handler"
OnUnload="OnUnload event handler"
runat="server"
/>
备注
使用 HtmlInputButton 控件可以对 <input type=button>、<input type=submit> 和 <input type=reset> HTML 元素进行编程。 用户单击 HtmlInputButton 控件时，来自嵌有该控件的窗体的输入被发送到服务器并得到处理。 然后，将响应发送回请求浏览器。
通过为 ServerClick 事件提供自定义事件处理程序，可以在单击控件时执行特定的指令集。
备注
reset 按钮不支持 ServerClick 事件。单击 reset 按钮时，不一定必须清除页上的所有输入控件。相反，在加载页时，它们返回到它们的原始状态。例如，如果文本框最初包含值“JohnDoe”，则单击 reset 按钮会使文本框返回到该值。
与 HtmlInputText 和 HtmlTextArea 控件一起使用时，可创建可以在服务器上处理的用户输入页或身份验证页。
备注
此控件不需要结束标记。
