在datalist里删除数据，后台删掉了，前台页面不刷新的问题

只有调试的时候才好使。不然只能刷新页面才显示删除后的新数据。请各位帮帮忙，谢谢大家。
if (!Page.IsPostBack)
{
string name = Request.QueryString["name"];
bind2();
}
public void bind2()
{
dt = new SonManager().SelectAll("3");
DLcon2.DataSource = dt;
DLcon2.DataKeyField = "id";
DLcon2.DataBind();
}
protected void DLcon2_DeleteCommand(object source, DataListCommandEventArgs e)
{
string id = DLcon2.DataKeys[e.Item.ItemIndex].ToString();
bool b = new SonManager().Delete(id);
if (b)
{
bind2();
Response.Write("<script>alert('删除成功!');</script>");
}
else
{
Response.Write("<script>alert('删除失败!');</script>");
}

bind2();
}
protected void DLcon2_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
string id = DLcon2.DataKeys[e.Item.ItemIndex].ToString();
}

Answer 1

如果想不刷新，最简单的就是用ajaxcontroltoolkit的updatepanel

Answer 2

用Ajax 的 ScriptManager +UpdatePanel 搞定

Answer 3

SonManager返回的是啥啊？SelectAll("3");前3条么？

Answer 4

删除以后 重新绑定一次
