Allowing items to be edited


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. However, the default behaviour of the control ignores the changes once the edit is complete. To allow the edit changes to be accepted, we have to add a handler to the LVN_ENDLABELEDIT notification. Here is a sample of a reflected message handler (e.i. the message is handled by the list view control itself, rather than the parent window).
void CMyListCtrl::OnEndLabelEdit(NMHDR* pNMHDR, LRESULT* pResult)
{
        *pResult = TRUE;
}
If we set *pLResult to FALSE, the changes are ignored. Allowing edits of sub items are not directly supported by the control but can be easily implemented. It is covered in a different section.

  • How can I select item in this function?

    but it does not work. The case is like you rename a folder name to a existing folder in Windows Explorer. How can I still keep focus on the editing item.

  • Problem with LVN_BEGINLABELEDIT

    LVN_ENDLABELEDIT works fine for me, but I have a problem when I do not want to allow editing some labels. I don't want to even start the editing process, when user clicks on some labels. I have read that I have to return TRUE in respond to the LVN_BEGINLABELEDIT, but this does not work. Any suggestions?
