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.
