动态添加的DropDownList控件如何设置AutoPostBack属性?

Question

            DropDownList ddlist = new DropDownList();
            ddlist.ID = "proddllist" ;
            ddlist.ddlist.AutoPostBack = true;
 那AutoPostBack 执行的函数该怎么添加呢?

Answer 1

    protected void Button1_Click(object sender, EventArgs e)
    {
        DropDownList ddlist = new DropDownList();
        ddlist.ID = "proddllist";
        ddlist.AutoPostBack = true;
        ddlist.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);
       
    }
   
    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {    }

Answer 2

ddlist.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);

Answer 3

如果是增加JS事件
你依然可以在前台代码中写入静态的，也可以在后台PageLoad时加入，例如我给DropDownList加个Onclick事件：DropDownList1.Attributes("onclick", "function{}//JS方法名");
而服务端事件，如几位楼上所说的方法，但是在VS2005中，
DropDownList1.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);似乎是没必要自己写，由平台自动会给你建立，前提是你的AutoPostBack 设为了True

Answer 4

用(DropDownList)findcontrol(ddID)来操作该dropdownlist

Answer 5

ddlist.SelectedIndexChanged += delegate(object sender, EventArgs e){//Code here};

Answer 6

想偷懒也可以使用
 ddlist.SelectedIndexChanged += delegate { Response.Write(ddlist.SelectedItem.Text); };
