--------------------编程问答-------------------- protected void DetailsView1_ItemUpdated(object sender, DetailsViewUpdatedEventArgs e)
{
DetailsView myDetailsView = (DetailsView)(sender);

}

if (DetailsView1.CurrentMode == DetailsViewMode.Edit)//编辑模式
        {
            string b = ((TextBox)DetailsView1.FindControl("TextBox1")).Text;
        }
