使用ListView insertitem+LINQ to SQL模板插入数据后，如何取到刚新添数据的Int identity值？

Question

protected void LinqDataSource_Inserted(object sender, LinqDataSourceStatusEventArgs e)
{
    if (e.Exception == null)
    {
        Product newProduct = (Product)e.Result;
        Literal1.Text = "The new product id is " + newProduct.ProductID;
        Literal1.Visible = true;            
    }
    else
    {
        LogError(e.Exception.Message);
        Literal1.Text = "We are sorry. There was a problem saving the record. The administrator has been notified.";
        Literal1.Visible = true;
        e.ExceptionHandled = true;            
    }
}

起先老是在listview 的 listview1_iteminserted()里打转，搞来搞去，不得要领，后来看了国外某blog，提到需要在linqdatasource的inserted（）事件里取。于是翻了MSDN，方才实践一下，确是可以。本人新手，把刚才的做法贴上来，也许是火星了。有更好的方法告诉俺。
