LinqDataSource.Inserted LinqDataSource.Inserted LinqDataSource.Inserted LinqDataSource.Inserted Event

定義

挿入操作が終了したときに発生します。Occurs when an insert operation has finished.

public:
 event EventHandler<System::Web::UI::WebControls::LinqDataSourceStatusEventArgs ^> ^ Inserted;
public event EventHandler<System.Web.UI.WebControls.LinqDataSourceStatusEventArgs> Inserted;
member this.Inserted : EventHandler<System.Web.UI.WebControls.LinqDataSourceStatusEventArgs> 
Public Custom Event Inserted As EventHandler(Of LinqDataSourceStatusEventArgs) 

次の例では、例外を確認し、新しいInsertedレコードの identity プロパティを取得するイベントのイベントハンドラーを作成する方法を示します。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

注釈

挿入操作Insertedから例外をキャッチしたり、挿入操作の完了後に値を調べたりするには、イベントを処理します。Handle the Inserted event to catch any exceptions from the insert operation or to examine the values after the insert operation has finished. イベントハンドラーに渡されるLinqDataSourceStatusEventArgsオブジェクトを使用して、新しい値を取得できます。You can retrieve the new values through the LinqDataSourceStatusEventArgs object that is passed to event handlers. たとえば、 LinqDataSourceStatusEventArgsオブジェクトを使用して、データベースによって生成された新しいデータレコードの id プロパティを取得できます。For example, you can use the LinqDataSourceStatusEventArgs object to retrieve the identity property generated by a database for a new data record.
