LinqDataSourceInsertEventArgs::ExceptionHandled Property
Gets or sets a value that indicates whether the exception was handled and that it should not be thrown again.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
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.
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
[C#]
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;
}
}
