从代码后面添加表单onsubmit()

Question

如何在子页面后面的代码中修改母版页asp.net项目表单的onsubmit参数?

我想更新的形式值是这样的:

<form id="form1" runat="server" onsubmit="SetPostbackValues()">

Answer 1

试试下面-

((System.Web.UI.HtmlControls.HtmlForm) Master.FindControl("form1")).Attributes.Add("onsubmit",
            "javascript:return SetPostbackValues();");
