Question

这是我在Visual Studio中的Web表单。用户单击“提交”按钮后，将显示另一个视图，感谢他们填写表单，但该按钮仍显示在页面上并带有感谢信息。如何点击后消失？

Answer 1

您可以将按钮添加到PanelNameForm，然后单击它后可以隐藏整个面板。在Onclick_button事件添加。

PanelThankYou.Visible = true
PanelNameForm.Visible = false

Answer 2

普通的通常做法是重定向到单独的＆＃34;谢谢你＆＃34;表格提交页面。

在您的情况下，您可以简单地添加

Button.Visible = False

进入按钮的点击事件。（顺便说一句，您可能希望将按钮的ID更改为与保留字不同的内容）。

Answer 3

在设计代码中设置autopostback = true，

然后在你的代码后面的类文件检查ispagepostback属性，如果它的真实提交说谢谢你加载新页面或隐藏谢谢你的消息..

单击“提交”按钮后消失
