I have a question about property category. When I create the control in this sequence:

Create CExtPropertyItem name "Symbol"
Create CExtPropertyItem name "Model"
Create CExtPropertyCategory name "A?" and add one item in it

I got the result in this sequence
<Property Category A?>
<Child property item of the category>
<Property item "Symbol">
<Property item "Model">

But when I change the name of the category to be "a?" (the lower case of "A"), I got this result
<Property item "Symbol">
<Property item "Model">
<Property Category a?>
<Child property item of the category>

Shouldn’t the category item be the last item no matter what the name it is? Or if I want the control to be in that way, what should I do?

Even in CExtPropertyGridWndCategorized window, the categories and/or values can be sorted alphabetically. To turn these off, you should use this code:

	CExtPropertyGridWndCategorized * pGrid =
		STATIC_DOWNCAST(
			CExtPropertyGridWndCategorized,
			m_wndPropertyGridCtrl.GetChildByRTC(
				RUNTIME_CLASS(CExtPropertyGridWndCategorized)
				)
			);
	if( pGrid != NULL ) {
		pGrid->m_bSortedCategories = false;
		pGrid->m_bSortedValues = false;
	}
