I want to add combo box and edit control in multiple rows but inside single column in clistctrl

The generic CListCtrl provides no support for columns with embedded controls. If you need those you have to create your own CListCtrl based class supporting that as provided by solutions you have probably found already.

But those are doing that column wise because that is the intention of such lists. If you want the controls for specific cells only, you have to extend those solutions. You have to create the embedded controls and store it's window handles or pointers in another list. You need also some kind of lookup function that returns those handles for a specific row and column. The list has to be custom draw (let the embedded control redraw itself instead of using the default list item drawing) and provide activation of the embedded controls (setting the focus) upon several mouse and keyboard events.

A simpler method might be using overlay controls. That is creating the controls dynamically when activating a specific cell (e.g. by double clicking or via context menu) and setting the focus to them. Once the edit / selection has been done, the list cell can be updated, the temporary control is deleted, and focus is returned back to the list. But with this method there will be no indication of cells that provide selection or edit.
