使用PlaceHolder 和 Panel都行， Panel1.Controls.Add(new Label());想控制位置首先声明一下Label
Label lb1 = new Label();
lb1.Text="this is my lable";
lb1.Style = ...... ;
Panel1.Controls.Add(lb1);

Thanks! I used PlaceHolder combined with Tablerow and TableCell so I can add controls in the way I like to display.

Thanks! By the way, how can i trigger an event on a dynamic generated control or get a value from it.

I had a piece of code using similar techonolgy, but it doesn't work. Instead of the linkbutton, i created dropdownlist dynamicly. Can you help me to take a look why my code doesn't work.

建议你先读一读有关书籍或相关网站,你的问题是比较普遍的. 我猜是ViewState的问题. 处理不好的话dynamic controls的viewstate可能在postback后就丢了.一个方法检查,就是在IE里view source,看有没有你的__doPostBack function.建议你多Google. 比在这里问问题快得多. :-)

Sorry for later reply. you should call the dynamic function in both page load and post back.
