// Summary:
//     CXTPPropertyGridItemNumber is a CXTPPropertyGridItem derived class.
//     It is used to create an integer value item in a Property Grid control.
//===========================================================================
class _XTP_EXT_CLASS CXTPPropertyGridItemNumber : public CXTPPropertyGridItem
{
public:

	//-----------------------------------------------------------------------
	// Summary:
	//     Constructs a CXTPPropertyGridItemNumber object
	// Parameters:
	//     strCaption  - Caption of the item.
	//     nID         - Identifier of the item.
	//     nValue      - Initial value of item.
	//     pBindNumber - If not NULL, then the value of this item
	//                   is bound the value of this variable.
	// Remarks:
	//     Class CXTPPropertyGridItemNumber has no default constructor.
	//
	//          When using the second constructor, the Identifier (nID) of the
	//          second constructor can be linked with a STRINGTABLE resource
	//          with the same id in such form "Caption\\nDescription".
	//
	//          BINDING:
	//            Variables can be bound to an item in two ways, the first is
	//            to pass in a variable at the time of creation, the second allows
	//            variables to be bound to an item after creation with the
	//            BindToNumber member.
	//
	//            Bound variables store the values of the property grid items
	//            and can be accessed without using the property grid methods
	//            and properties.  Bound variables allow the property grid to
	//            store data in variables.  When the value of a PropertyGridItem
	//            is changed, the value of the bound variable will be changed to
	//            the PropertyGridItem value.  The advantage of binding is that
	//            the variable can be used and manipulated without using
	//            PropertyGridItem methods and properties.
	//
	//            NOTE:  If the value of the variable is changed without using
	//            the PropertyGrid, the PropertyGridItem value will not be
	//            updated until you call CXTPPropertyGrid::Refresh.
