求教DropDownList实现分页跳转

求教高手，怎么用DropDownList实现girdview分页跳转?我的部分代码如下，无法跳转，请问错在哪里？应该怎么改？
protected void bindtodg(int myclassid)
{
........
this.topicdg.DataSource = dt;
this.topicdg.DataBind();
this.nowpage.Text = (this.topicdg.PageIndex + 1).ToString();
this.totalpage.Text = this.topicdg.PageCount.ToString();
this.pagelist.Items.Clear();
for (int i = 1; i <= this.topicdg.PageCount; i++)
{
this.pagelist.Items.Add(i.ToString());
}
this.pagelist.SelectedIndex = this.topicdg.PageIndex;
}

protected void pagelist_SelectedIndexChanged(object sender, EventArgs e)
{
this.topicdg.PageIndex = this.pagelist.SelectedIndex;
bindtodg(1);
}
AutoPostBack已设为true

Answer 1

是不是DropDownList的AutoPostBack没有设为“true”。
（选择页数时，页面没有刷新？）
