禁用动态创建的按钮的回发

Question

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" Runat="Server">
    <asp:Panel ID="Panel1" runat="server">
        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    </asp:Panel>    
</asp:Content>

public partial class Page1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack == true)
        {
            btn_Click(sender, e);
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Button btn = new Button();
        btn.Text = "Dynamic button";
        btn.Click += btn_Click;
        Panel1.Controls.Add(btn);
    }

    void btn_Click(object sender, EventArgs e)
    {
        Response.Redirect("../Page2");
    }
}

从这段代码中，当单击“button1”时，它应该创建一个新按钮“btn”，当单击“btn”时，它应该转到其click函数中的url（即btn_Click())。但是当我单击“button1”时，它不执行“button1_click()”，而是执行“btn_click()”。我该怎么办？？

Answer 1

if (IsPostBack == true)

可以成为

if (IsPostBack)

然后

Response.Redirect("../Page2");

可以成为

Response.Redirect("~/Page2");

<asp:Button runat="server" ID="Button1" OnClick="Button1_Click"></asp:Button>
