LinqDataSourceInsertEventArgs.ExceptionHandled Property

Definition

Gets or sets a value that indicates whether the exception was handled and that it should not be thrown again.

public:
 property bool ExceptionHandled { bool get(); void set(bool value); };
public bool ExceptionHandled { get; set; }
member this.ExceptionHandled : bool with get, set
Public Property ExceptionHandled As Boolean

Property Value

true if the exception was handled; otherwise, false.

Examples

The following example shows an event 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

You can create event handlers for the Inserting event to examine validation exceptions that occurred before the insert operation. If you handle the exception and do not want it to be thrown again, set the ExceptionHandled property to true. If you do not set the ExceptionHandled property to true, the exception will be propagated to the next event handler in the call stack.
