LinqDataSource.Inserted 事件

定義

命名空間:

System.Web.UI.WebControls

組件:

System.Web.Extensions.dll

在插入作業完成時發生。

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) 

事件類型

EventHandler<LinqDataSourceStatusEventArgs>

範例

下列範例示範如何為 Inserted 檢查例外狀況的事件建立事件處理常式，並擷取新記錄的識別屬性。

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

備註

Inserted處理 事件以攔截插入作業的任何例外狀況，或檢查插入作業完成後的值。 您可以透過 LinqDataSourceStatusEventArgs 傳遞至事件處理常式的物件擷取新值。 例如，您可以使用 LinqDataSourceStatusEventArgs 物件來擷取資料庫針對新資料記錄所產生的識別屬性。
