protected:
virtual void OnItemValueNeeded(
    DataRepeaterItemValueEventArgs^ e
)

abstract OnItemValueNeeded : 
        e:DataRepeaterItemValueEventArgs -> unit
override OnItemValueNeeded : 
        e:DataRepeaterItemValueEventArgs -> unit

    e As DataRepeaterItemValueEventArgs

Parameters

• e
  Type: Microsoft.VisualBasic.PowerPacks.DataRepeaterItemValueEventArgs

  An object that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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.
