Indicates that the property supports data binding.
[bindable]
Remarks
The bindable C++ attribute has the same functionality as the bindable MIDL attribute. You can use it on properties defined with the propget, propput, or propputref attributes, or you can manually define a bindable method.
The following MFC samples show the use of bindable. All samples can be found in the Visual C++ Samples topic:
Controls Samples: MFC-Based ActiveX Controls
CIRC Sample: ActiveX Control
TESTHELP Sample: ActiveX Control with Tooltips and Help
Example
The following code shows how you can use bindable on a property:
// cpp_attr_ref_bindable.cpp
// compile with: /LD
#include <windows.h>

[propget, id(1), bindable, displaybind, defaultbind, requestedit] HRESULT P1([out, retval] long *nSize);
[propput, id(1), bindable, displaybind, defaultbind, requestedit] HRESULT P1([in] long nSize);
[id(3), bindable, propget] HRESULT Object([out, retval] IDispatch **ppObj);
[id(3), bindable, propputref] HRESULT Object([in] IDispatch* pObj);
