Change Tab as container

I know that we can use InserItem to set the inserted tab in a new tab.

Instead I can't find a method to move a grid (TDBGrid) control between different existings tab.

Example: I have a TabControl1 with three tabs (with no TabPage) and a grid on first tab (0).
when I select a different tab (1 or 2) I want to move the grid on new selected tab.

I tried this, but get Out of memory error:

Private Sub TabControl1_BeforeItemClick(ByVal Item As XtremeSuiteControls.ITabControlItem, Cancel As Variant)
    Dim curTab As TabControlItem
    Set curTab = Item
    Set TDBGrid1.Container = curTab    '<- Error 7 - Out of memory
End Sub

How to?
SuiteControl 15.3.1
