LinqDataSourceUpdateEventArgs::Exception Property
Visual Studio 2010
Gets the exception that was thrown while the data was being validated before the update 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 raised before the update operation is performed, the exception is stored in the Exception property. In an event handler for the Updating event, you can retrieve the exception through the Exception property.
The following example shows an event handler for the Updating event. It displays any validation exception messages by using a Label control.
Protected Sub LinqDataSource_Updating(ByVal sender As Object, _ ByVal e As LinqDataSourceUpdateEventArgs) 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_Updating(object sender,
LinqDataSourceUpdateEventArgs 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;
}
}
