Resizing column in list control

[jayshml]

Hi, when you resize a column in list control which event gets triggered?

[Vancouver]

OnBegintrack and OnEndtrack

How to add those event handlers?

[Vancouver]

BEGIN_MESSAGE_MAP(GridClass, CListCtrl) //{{AFX_MSG_MAP(yourclass) ... //}}AFX_MSG_MAP ON_NOTIFY(HDN_BEGINTRACKA, 0, your_OnBegintrack) ON_NOTIFY(HDN_BEGINTRACKW, 0, your_OnBegintrack) ON_NOTIFY(HDN_ENDTRACKA, 0, your_OnEndtrack) ON_NOTIFY(HDN_ENDTRACKW, 0, your_OnEndtrack) END_MESSAGE_MAP() Note, that the control id of the CHeaderCtrl in CListCtrl is always zero; thus, the second parameter (that is the control filter) in the ON_NOTIFYs is zero. The "A" and "W" versions are for ANSI and UNICODE (Wide) environment; in any given program run, only one or the other will become active. Btw, OnBegintrack receives control, when the user grabs the right-side divider of a column with the mouse (starting resizing). OnEntrack receives control, when the user releases the divider. The parameters are: void yourClass::your_OnBegintrack(NMHEADER *nmheader, LRESULT* pResult) void yourClass::your_OnBegintrack(NMHEADER *nmheader, LRESULT* pResult) (*nmheader).iItem is the column index from zero. *pResult should be set to TRUE if you don't allow resizing (TRUE indicates, that you processed the event completely), and FALSE, if you want MFC to finalize resizing.

No this is not working? Actually I want to resize a control in list subitem as I increase or decrease column width.I am handling this in OnCustomDraw() but it is flickering.I want to set SetRedraw() to TRUE and FALSE but in which event should I do that?
