Need to ResetDataSource conditionally in within a Collection

Ernest Noa

I have an EditDataForm spec. I am trying to rebind a FormField named EDUCATIONALHISTORYID that uses a simple data list when the CONSTITUENTID field is updated. The simple data list takes CONSTITUENTID as a parameter. I have code to do this when the when the UIFieldChanged event fires. This causes a loop, the event fires correctly when the CONSTITUENTID is changed, and then it updates EDUCAITONALHISTORYID which causes it to fire again and begin looping.

I need a way to know that it was the CONSTITUENTID field that was changed, or some other solution.

Public Class BulkEditFundRecipientDataFormUIModel

Private Sub BulkEditFundRecipientDataFormUIModel_UIFieldChanged(sender As Object, e As UIFieldChangedEventArgs) Handles Me.UIFieldChanged

For Each m In DESIGNATIONRECIPIENT.Value

If m.Selected = True Then

m.EDUCATIONALHISTORYID.ResetDataSource()

End If

Next

End Sub

End Class

Normally I would just debug, and peer into “e” and see what I’ve got. Unfortunately in my current situation I have no debugging ability.

You should be able to handle CONSTITUENTID.ValueChanged instead of Me.UIFieldChanged. This will only fire when constituent id changes instead of when anything changes.

Edit: Inside the collection field's UI model.
