The exception, if an error occurred; otherwise, null.

Examples

The following example shows a handler for the Inserting event. It displays any validation exception messages by using a Label control.

Protected Sub LinqDataSource_Inserting(ByVal sender As Object, _  
        ByVal e As LinqDataSourceInsertEventArgs)  
    If (e.Exception IsNot Nothing) Then  
        For Each innerException As KeyValuePair(Of String, Exception) _  
               In e.Exception.InnerExceptions  
            Label1.Text &= innerException.Key & ": " & _  
                innerException.Value.Message + "<br />"  
        Next  
        e.ExceptionHandled = True  
    End If  
End Sub

protected void LinqDataSource_Inserting(object sender,   
        LinqDataSourceInsertEventArgs e)  
{  
    if (e.Exception != null)  
    {  
        foreach (KeyValuePair<string, Exception> innerException in   
             e.Exception.InnerExceptions)  
        {  
        Label1.Text += innerException.Key + ": " +   
            innerException.Value.Message + "<br />";  
        }  
        e.ExceptionHandled = true;  
    }  
}

Remarks

If a validation exception is thrown before the insert operation is performed, the exception is stored in the Exception property. In a handler for the Inserting event, you can retrieve the exception through the Exception property.
