DataGridView::OnDataError Method (Boolean, DataGridViewDataErrorEventArgs^)
.NET Framework (current version)
Raises the DataError event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
protected: virtual void OnDataError( bool displayErrorDialogIfNoHandler, DataGridViewDataErrorEventArgs^ e )
Parameters
- displayErrorDialogIfNoHandler
-
Type:
System::Boolean
true to display an error dialog box if there is no handler for the DataError event.
- e
-
Type:
System.Windows.Forms::DataGridViewDataErrorEventArgs^
A DataGridViewDataErrorEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnDataError method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When overriding OnDataError in a derived class, be sure to call the base class’s OnDataError method so that registered delegates receive the event.
