要在编辑模式下获取Dropdownlist的SelectedValue，请在RowDataBound事件中使用以下代码，

To get the SelectedValue of Dropdownlist in Edit Mode, use the below code in RowDataBound Event,

DataRowView drv = (DataRowView)e.Row.DataItem;
if (e.Row.RowType == DataControlRowType.DataRow)
{
   if ((e.Row.RowState & DataControlRowState.Edit) > 0)
   {
      DropDownList ddl= (DropDownList )e.Row .FindControl ("DropDownList1");
      ddl.SelectedValue = drv[3].ToString();
   }
}
