DataRepeater.OnItemValueNeeded Method

Raises the ItemValueNeeded event.

Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

protected virtual void OnItemValueNeeded(
	DataRepeaterItemValueEventArgs e


Type: Microsoft.VisualBasic.PowerPacks.DataRepeaterItemValueEventArgs

An object that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnItemValueNeeded method also enables 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 you override OnItemValueNeeded in a derived class, make sure to call the OnItemValueNeeded method of the base class so that registered delegates receive the event.
