Esempi

Nell'esempio seguente viene illustrato come creare un gestore eventi per l' Inserted evento che controlla le eccezioni e recupera la proprietà Identity per il nuovo record.The following example shows how to create an event handler for the Inserted event that checks for exceptions and retrieves the identity property for the new record.

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;            
    }
}
Protected Sub LinqDataSource_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LinqDataSourceStatusEventArgs)
    If (IsNothing(e.Exception)) Then
        Dim newProduct As Product
        newProduct = CType(e.Result, Product)
        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
    End If
End Sub

Commenti

Gestire l' Inserted evento per intercettare eventuali eccezioni dall'operazione di inserimento o per esaminare i valori al termine dell'operazione di inserimento.Handle the Inserted event to catch any exceptions from the insert operation or to examine the values after the insert operation has finished. È possibile recuperare i nuovi valori tramite l' LinqDataSourceStatusEventArgs oggetto passato ai gestori eventi.You can retrieve the new values through the LinqDataSourceStatusEventArgs object that is passed to event handlers. Ad esempio, è possibile utilizzare l' LinqDataSourceStatusEventArgs oggetto per recuperare la proprietà Identity generata da un database per un nuovo record di dati.For example, you can use the LinqDataSourceStatusEventArgs object to retrieve the identity property generated by a database for a new data record.
