If you weren’t satisfied with the answer to this same issue in the previous topic then maybe this one will. However, there is a big risk involved. It uses some undocumented features of MFC and maybe I haven’t got all the angles covered. So use this at your own RISK. The basic idea to make […]

Override CListCtrl::OnNotify as follows : BOOL CMyListCtrl::OnNotify(WPARAM wParam, LPARAM lParam, LRESULT*pResult) { HD_NOTIFY *pHD = (HD_NOTIFY*)lParam; if ((pHD->hdr.code == HDN_ITEMCHANGINGA || pHD->hdr.code == HDN_ITEMCHANGINGW) && (GetStyle() & LVS_TYPEMASK) == LVS_REPORT) { // Invalidate empty bottom part of control to force erase the previous position of column int nBottom,nLastItem=GetItemCount()-1; if (nLastItem

The list view control does not provide for any visual delineation between the columns in the report mode. The code below shows how to add vertical lines between columns. To do our own drawing we override the OnPaint() function. Since we dont want to do all the rendering of the control, we let DefWindowProc() take […]

To draw horizontal and vertical gridlines we essentially use the same method used for the vertical gridline or column border used in the previous section. After drawing the vertical lines, we use GetItemRect() to get the item height and then we draw the horizontal grid lines based on this height. One implication of using GetItemRect() […]

Normally an edit is initiated when a user clicks on an item that already has the focus. Suppose, you want to start the edit when the user clicks a button, here is the code to start the edit. m_listctrl.SetFocus(); m_listctrl.EditLabel(nItem); You should remember to SetFocus() if the listview control does not already have the focus. […]

The default implementation of the ListView control allows editing of the first column label only. You have to create your own edit control to allow editing of subitems. Step 1: Derive a class from CListCtrl In the code below, CMyListCtrl is the name used for the derived class. You can also derive a class from […]

This article illustrates two points:  another method of implementing subitem editing and the multiline edit control used in place of the single line edit control.  The basis of this implementation comes from the article, “Editable Subitems“. Usage Tip: To insert a return in the edit control without finishing the edit, type Ctrl-Enter. This is part […]

Sometimes, instead of allowing the user to arbitrarily change the value of an item, you want to present the user with a set of choices. You can do this by bringing up a drop down list instead of an edit control. To implement this, we follow a pattern very similar to that used for editable […]

A list view control has to have the LVS_EDITLABELS style for it to be editable. This style can be set when creating the control or even later by using ModifyStyle(). Once we have set the LVS_EDITLABELS style, the user can set focus on an item and click on it again to begin editing the item. […]

This article was contributed by Wayne Berthin. This article describes how to impletment drag and drop rearrangement of rows in a list control with the report style. The drag operation starts when the user begins a left drag on any item label (in its left-most column). During the drag a ghost image of the item […]

Quite often the screen space available to the list view control is just not enough to display all the columns in the control. Also, very often, a user wants to rearrange the columns to his or her liking. The preferred way to deal with this is to allow dragging of the columns and thus allowing […]

When the list view control is in the report it usually displays a header control to label the columns. Often times we need to get hold of the header control. This header control is a child window of the list view control and always has the ID 0. CHeaderCtrl* pHeader =(CHeaderCtrl*)m_listctrl.GetDlgItem(0); The header control exists […]
