How to change the index of Header Item?

[mikert_2008]

Hi, I want to change the index of header Item on drag drop. If header item 0 drag drop to next header column(After HeaderCol 1) then change the index of Header item 0 to 1. & Header Item 1 index to 0. I am using GetItem() & SetItem() but that's not working. How to do this? Please make the correction in the code:- On DragDropFunc() { HDITEM pHeaderItemCurrent,pHeaderItemNew; TCHAR lpBuffer[256]; TCHAR lpBuffer1[256]; pHeaderItemCurrent.pszText = lpBuffer; pHeaderItemCurrent.cchTextMax = 256; pHeaderItemNew.pszText = lpBuffer1; pHeaderItemNew.cchTextMax = 256; m_HeaderCtrl.GetItem(0,&pHeaderItemCurrent); m_HeaderCtrl.GetItem(1,&pHeaderItemNew); m_HeaderCtrl.SetItem(0, &pHeaderItemNew); m_HeaderCtrl.SetItem(1, &pHeaderItemCurrent); } Thanks:- Mike

Are you in search of this ? m_mylistcontrol.SetExtendedStyle(LVS_EX_HEADERDRAGDROP);

You need to google first, if you have "It's urgent please" mentioned in your question. ;-)_AnShUmAn_

NO. I have already added the HDS_DRAGDROP while creating the header control. What I need is to change the header Id which we specify while insertion. i.e m_header.InsertItem(columnId, &hditem);//columnId =1; Now How Can assign the some different hditem to columnId = 1; I try with SetItem() as in code but its not working...... Any suggestion. Mike

Just one quick question. Why do you want to change the index of the item?
