Not able to remove eventhandler

Anonymous — Wed, 30 Mar 2016 18:36:03 GMT

I am using below eventhandler to add e.selectionadded event

AddHandler ed.SelectionAdded, AddressOf testit

And I am using below statement to remove it.

RemoveHandler ed.SelectionAdded, AddressOf testit

But it does not get removed.

My testit function,

Public viewmodel As New GetATT_ViewModel
 Public Sub testit(sender As Object, e As SelectionAddedEventArgs)
        Dim objectid() As ObjectId = e.AddedObjects.GetObjectIds

        viewmodel.getattribute(objectid)


    End Sub

I read somewhere that you need to make function shared but I can not make that as I am calling another function in it which is not shared.

I don't understand why you are handling SelectionAdded event if you just need to get the selected objects.

Why don't you complete the selection and then pass the selected objects to your viewmodel.getattribute() method ?

@_gile If you are talking about select object then user hits button to get information of that object, It will be manual right? Its like addign another step.

I wanted whenever user selects block, palete displayes its attributes, thats why I aded ed.selectionadded event handler

I hope it clarifies

Thanks,
