Generic Event Handling

I want to access an event that doesnt exist at desingtime
as it is only an object or control, however I know it
will at runtime. This works with properties OK but with
events it wont accept it unless it exists at designtime.

Example:
WORKS!
dim obj as Control
obj=Combobox1
msgbox obj.SelectedIndex

DOESNT WORK!!
Private Sub Generic() Handles obj.SelectedValueChanged

Hi Robby,

I think you may consider the AddHandler method in .NET. For example:

Dim obj as ComboBox

obj=Combobox1

AddHandler Obj.SelectedValueChanged, AddressOf EventHandler

For more information about AddHandler, you may refer to:

Please reread my original post as I think you have missed
the point. I cannot declare a ComboBox only a Control.

Hi Robby,

If we only can define it as Object, can we know the events it have, like
SelectedValueChanged? I think you may take a look at .NET refelction to see
if it will help on this issue:
