I need a specific sorting in a property category of a CExtPropertyGridCtrl. Now cells and subcategories are sorted in alphabetical order. I want subcategories to be sorted first and placed at the begining, and then all other cells the same. For example:

I have:

Category1
Category 2
Property1
SubCategory 1
subProperty1
subproperty2
.......
Property2
SubCategory 2
subProperty1
subProperrty2
..........
...........

I need:

Category1
Category 2
SubCategory 1
subProperty1
subproperty2
.......
SubCategory 2
subProperty1
subProperrty2
..........
Property1
Property2
...........

Please, can you explain me how to do that?

The property item order like you need can be organized using the following two conditions:

1) You should invoke the following code before assigning the property store to the property grid control:

CExtPropertyGridCtrl * pPGC = . . .
CExtPropertyGridWnd * pPGW =
    STATIC_DOWNCAST( CExtPropertyGridWnd,
        pPGC->GetChildByRTC( RUNTIME_CLASS( CExtPropertyGridWndCategorized ) ) );
    pPGW->m_bSortedCategories = false;

2) You should insert your property values and property categories into each sublevel of the property tree using the same order which you want to see on the screen. The previous step turnes off any sorting in the property grid.

Thank you, very much.
