推荐答案

这是想法是创建一个按钮列表中，你会保存您在btnCreateDynamic_click创建的按钮。

An idea would be to create a list of buttons in which you'd store the buttons you created in btnCreateDynamic_click.

您可以有这样的方法：

private Button CreateButton(string id, string name) { Button b = new Button(); b.Text = name; b.ID = id; b.Click += new EventHandler(Button_Click); b.OnClientClick = "ButtonClick('" + b.ClientID + "')"; return b; }

在btnCreateDynamic_click你可以有这样的：

in btnCreateDynamic_click you could have something like:

Button b = CreateButton("dinamicBtn"+myDinamicButtonsList.Count.ToString(),"dinamicBtn"+myDinamicButtonsList.Count.ToString()); myDinamicButtonsList.add(b);

，并在页面加载，例如，你可以不喜欢

and in the pageLoad for example you could do something like

foreach(button btn in myDinamicButtonsList){ form1.Controls.Add(btn)); } List<Button> myDinamicButtonsList = new List<Button>();

myDinamicButtonsList应某处，从那里可以每个请求后检索存储

myDinamicButtonsList should be stored somewhere from where it could be retrieved after each request.

修改： 在页面加载，你可以有这样的事情：

EDIT: In page load you could have something like this:

if(Session["myDinamicButtons"] == null){ List<Button> myDinamicButtonsList = new List<Button>(); Session["myDinamicButtons"] = myDinamicButtonsList; } foreach(Button btn in Session["myDinamicButtons"] as List<Button>){ form1.Controls.Add(btn)); }

我没有测试它，但它应该工作。

i didn't tested it but it should work.
