LinqDataSourceInsertEventArgs::Exception Property
Visual Studio 2010
Gets the exception that was thrown while the data was being validated before the insert operation.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
public: property LinqDataSourceValidationException^ Exception { LinqDataSourceValidationException^ get (); }
Property Value
Type: System.Web.UI.WebControls::LinqDataSourceValidationExceptionThe exception, if an error occurred; otherwise, nullptr.
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.
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
[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;
}
