推荐答案

您好，

您只需在登录按钮点击事件中做到这一点:

Hi,

You just do like this in the sign in button click event:

Control uc = LoadControl("YourLoginWebUserControl.ascx");
YourPlaceHolder.Controls.Add(uc);

然后，请记住在以下回发中重新创建控件，否则，如果usercontrol引发了任何按钮单击事件，则它们不会在后面的代码中触发.

就这样:-)

And then, remember to re-create the control in the following postback''s otherwise if the usercontrol was raising any button click events or so, they will not get fired in the code behind.

That''s it :-)

最简单的方法是将用户控件从解决方案资源管理器面板拖放到要放置的页面的内容占位符上.我希望它能给你一个主意. :)

the easiest way to do is to drag and drop the user control from the solution explorer panel to the content place holder of a page you want it to place. i hope itll give you an idea. :)
