Visual C++ MFC - CListCtrl - Insert Column and Item





MFC list control - CListrCtrl is widely used in GUI Application as it supports report list view. This enables the users to have row and columns which would simulate like grid functionality. The CListCtrl::InsertColumn(...) function is used to insert a new column in the report view modal. CListCtrl::SetColumnWidth is used for setting the width of the column.

 

Once columns are inserted, the adding the items to the MFC list control are tricky. As we need to use CListCtrl::InsertItem when we add a new row element for the first column. The subsequent columns for the same row can be filled with CListCtrl::SetItem(...) function. LV_ITEM struct defines the property of the MFC List Ctrl elements - LVIF_TEXT, etc. You can also add images, if required by changing the property.
