急，俺 在等

PlaceHolder ph = new PlaceHolder();
ph.ID = "fd";
for (int i = 1; i <= 3; i++)
{
Label label = new Label();
label.ID = "lbl" + i;
label.Text = "<a href=></a>";
ph.Controls.Add(label);

}


form1.Controls.Add(ph);
运行后label没有显示，这怎么回事啊?

[PandaIT]

<asp:PlaceHolder id="PlaceHolder1"
runat="server"/>


页面上放一个这样的！！

然后再添加！！

Button Button1 = new Button();
    Button1.Text = "Button 1";
    PlaceHolder1.Controls.Add(Button1);
    
    Literal Literal1 = new Literal();
    Literal1.Text = "<br>";
    PlaceHolder1.Controls.Add(Literal1);
    
    Button Button2 = new Button();
    Button2.Text = "Button 2";
    PlaceHolder1.Controls.Add(Button2);

动态添加不太会，DD

[mynameishuchao]

还是不行

[zhujiazhi]

PlaceHolder ph = new PlaceHolder();

ph.ID = "fd";
for (int i = 1; i <= 3; i++)
{
Label label = new Label();
label.ID = "lbl" + i;
label.Text = " <a href=''>123</a>";
ph.Controls.Add(label);

}

this.Controls.Add(ph);

这个可以显示的
