Disable/Hide Items in a CListCtrl MFC

I want to hide or disable Items with SetItemState(). The CListCtrl is in Report View. It must be something like this m_List.SetItemState(1, DISABLE, DISABLE);

I searched but didnt find the right nState

If there is another solution than SetItemState, it also will be ok

Can anyone help me?

You can give visual feedback. I would derive a class CMFCListCtrl and override OnGetCellBkColor and OnGetCellTextColor methods to achieve it.

And I would override the its response to selection to unselect when selecting an unselectable item. However for this part, I am not so sure if it is doable.

There is no item state to represent a disabled (grayed) item. See docs The only way to solve this is your own implementation and using custom draw. That is the way I do it.

You can easily prevent the user to select an item when you trap LVN_ITEMCHANGING. Just filter the state Change to LVIS_SELECTED and return TRUE to prevent the change.
