List Control 列表項目上下移動實現：刪除重插法完整教學

編輯：關於VC++

核心思路

取得選中項索引 → 讀取全欄文字 → DeleteItem → InsertItem 於目標位置 → 恢復選中狀態。簡單高效，適合報表模式 CListCtrl。

關鍵程式碼

記錄選中索引


void CLCDemoDlg::OnClickList(NMHDR* pNMHDR, LRESULT* pResult) {
    POSITION pos = m_listCtrl.GetFirstSelectedItemPosition();
    IndexInFieldList = m_listCtrl.GetNextSelectedItem(pos);
    *pResult = 0;
}

向上移動


void CLCDemoDlg::OnButtonUp() {
    m_listCtrl.SetFocus();
    if (IndexInFieldList <= 0) { AfxMessageBox(_T("已在第一行!")); return; }

    CString c1 = m_listCtrl.GetItemText(IndexInFieldList, 0);
    CString c2 = m_listCtrl.GetItemText(IndexInFieldList, 1);
    CString c3 = m_listCtrl.GetItemText(IndexInFieldList, 2);

    m_listCtrl.DeleteItem(IndexInFieldList);
    int n = m_listCtrl.InsertItem(IndexInFieldList-1, c1);
    m_listCtrl.SetItemText(n, 1, c2);
    m_listCtrl.SetItemText(n, 2, c3);

    IndexInFieldList--;
    UINT flag = LVIS_SELECTED | LVIS_FOCUSED;
    m_listCtrl.SetItemState(IndexInFieldList, flag, flag);
}

向下移動 (邏輯對稱)


void CLCDemoDlg::OnButtonDown() {
    m_listCtrl.SetFocus();
    int cnt = m_listCtrl.GetItemCount();
    if (IndexInFieldList < 0 || IndexInFieldList >= cnt-1) {
        AfxMessageBox(_T("已在最後一行!")); return;
    }
    // 同樣讀取三欄文字
    m_listCtrl.DeleteItem(IndexInFieldList);
    int n = m_listCtrl.InsertItem(IndexInFieldList+1, c1);
    m_listCtrl.SetItemText(n, 1, c2);
    m_listCtrl.SetItemText(n, 2, c3);
    IndexInFieldList++;
    m_listCtrl.SetItemState(IndexInFieldList, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
}
