Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
type DataGridViewDataErrorEventHandler = delegate of sender:Object * e:DataGridViewDataErrorEventArgs -> unit
- Type: System.Object
The source of the event.
- Type: System.Windows.Forms.DataGridViewDataErrorEventArgs
A DataGridViewDataErrorEventArgs that contains the event data.
The DataError event is raised when an error occurs during a data processing operation in a data-bound DataGridView (for example, when a format or parse operation throws an exception or the update of the data source fails).
When you create a delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
The following code example demonstrates how to use a to display information about a DataError in a message box. This code is part of a larger example provided in the DataGridViewComboBoxColumn class overview topic.
