急！！求大神 帮帮忙 bandedGridView行定位

Question

双击选中的行 编辑完后调用bandedGridView1_RowUpdated这个事件 操作成功后
重新加载数据后 将选中行的FocusedRowHandle 重新赋给bandedGridView1
但是不管用 加载后选中的是默认的第一行
代码
private int focusedRowHandle = -1;
private void loadData()
{
gridControl1.DataSource = ds.Tables[0];
bandedGridView1.FocusedRowHandle = focusedRowHandle;
}
private void bandedGridView1_RowUpdated(object sender, DevExpress.XtraGrid.Views.Base.RowObjectEventArgs e)
{
var edrow = e.Row as DataRowView;
var list = new List();
focusedRowHandle = e.RowHandle;
if (ComClass.PClient.RunTransaction(list))
{
MessageBox.Show("操作成功！");
loadData();
}
else
{
MessageBox.Show("操作失败！");
}

请各位大神帮忙看看
