You can do this with CExtPropertyGridCtrl::GetChildByRTC() like as follows

CExtPropertyGridComboBoxBar * pCombo =
        STATIC_DOWNCAST(
            CExtPropertyGridComboBoxBar,
            m_PGC.GetChildByRTC(
                RUNTIME_CLASS(CExtPropertyGridComboBoxBar)
                )
            );
    if( pCombo == NULL )
        return;
    ASSERT_VALID( pCombo );

How I can get access to CExtPropertyGridComboBoxBar at CExtPropertyGridCtrl?

The CExtPropertyGridComboBoxBar::PropertyStoreInsert() method inserts a CExtPropertyStore object into the combo box bar inside the property grid control. The CExtPropertyGridComboBoxBar::PropertyStoreRemove() method removes a property store from the combo box bar. Please note, the C++ delete operator is never used in the property grid control for deleting CExtPropertyStore objects. This means it is your code that is responsible for deleting property stores.

If you need the combined properties view, then you should create a new CExtPropertyStore object and combine it with two basic property stores. This new combined property store would contain references to propery categories and values stored in two source property stores. You can insert the combined propery store into the property grid control absolutely just like you can do this just like a simple basic property store.

To combine the property store with others, please use its Combine() method.
