这段就可以了，

void Item_Bound(Object sender, DataGridItemEventArgs e)
{

if((e.Item.ItemType == ListItemType.Item) ||
(e.Item.ItemType == ListItemType.AlternatingItem))
{
DropDownList ddl = (DropDownList)e.Item.FindControl("DropDownList1");
ddl.DataSource = ds.Tables["authors"].DefaultView;
ddl.DataTextField = "au_lname";
ddl.DataValueField = "au_id";
ddl.DataBind();
ddl.Items.FindByValue(DataBinder.Eval(e.Item.DataItem,"au_id").ToString()).Selected = true;
}

写错

ItemDataBound事件
先找到那个控件，然后进行正常的绑定就可以了。
