DataGridView::OnRowErrorTextNeeded Method (DataGridViewRowErrorTextNeededEventArgs^)
.NET Framework (current version)
Raises the RowErrorTextNeeded event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
protected: virtual void OnRowErrorTextNeeded( DataGridViewRowErrorTextNeededEventArgs^ e )
Parameters
- e
-
Type:
System.Windows.Forms::DataGridViewRowErrorTextNeededEventArgs^
A DataGridViewRowErrorTextNeededEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnRowErrorTextNeeded 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 OnRowErrorTextNeeded in a derived class, be sure to call the base class’s OnRowErrorTextNeeded method so that registered delegates receive the event.
