I have a application where I have several different datagrids on one form.  I would like to use ONE set of buttons/events to handle ALL datagrids depending on which grid is the "active grid", instead of duplicating buttons for each one.  Is there a way to pass  an "active grid" object, or something similar so that the same single button event is used for all datagrids on the form?

As soon as you press a button, the active grid will lose focus, so the "active" grid will be come inactive.  You could have a private variable that keeps track of which grid is the active one, and is updated upon every grid's .GotFocus or .LostFocus event.

    Private dgActive As DataGrid

    Private Sub DataGrid_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.GotFocus, DataGrid2.GotFocus
        dgActive = CType(sender, DataGrid)
    End Sub

    Private Sub DataGrid_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGrid1.LostFocus, DataGrid2.LostFocus
        dgActive = Nothing
    End Sub

Then in your button events, you would just have to use reference dgActive as the datagrid to perform the operations on.
