Register event for Collection field in web event handler

Blackbaud CRM 

In last post I have mentioned how to register any event for any field in web event handler. I have a scenario to play with collection fields. I have 5 fields in single collection. And for instance, if I change 3rd field and based on this field change other field will have an impact . So in this case I need to register an event which will handle this. See below lines

Private Sub BatchCommitmentUpdateHandler_AfterLoad(sender As Object, e As EventArgs) Handles Me.AfterLoad         With Me.FieldChangedHandlers             '' If Commitment lookup id is selected then it will get the commitment details from the DATAFORMID_COMMITMETINFO             ''form and load all single values along with the collection values If FieldIsDefined("XMLSTANDARDMETRIC") Then .Add("XMLSTANDARDMETRIC\AMOUNT", AddressOf StandardMetricAmountValidation)        End With     End Sub Private Sub StandardMetricAmountValidation (ByVal e As FieldEventArgBase) ‘ Implement the custom logic here End Sub

Now, whenever user will change 3^rd field which is AMOUNT column in collection “XMLSTANDARDMETRIC” then it will enter into the method “StandardMetricAmountValidation” and in this method we can use custom implementation.
