    }

Answer 1

You could add that control to the page, but with Visible=false

<h4 id="error1" runat="server" Visible="false"></h4>

And then you can just set make it visible from the code beside:

error1.Visible = true;
error1.InnerText = "Some message";

有很多方法可以使猫皮化，但是一种方法是将HtmlGenericControl添加到WebForm中，然后将适当的标记（“ h3”或“ h4”）传递给构造函数。
