如何将 CListCtrl 中的项目设置为选中状态？

Question

ClistCtrl is set to single selection & single column in report view with no header.

I have tried SetItemState(0,LVIS_SELECTED,LVIF_STATE) and
SetSelectionMark(int index) but these don't work.

Answer 1

you also need to call SetSelectionMark after updating the item states.

SetItemState(prev_item, ~LVIS_SELECTED, LVIS_SELECTED);
SetItemState(new_selected_item, LVIS_SELECTED, LVIS_SELECTED);
SetSelectionMark(new_selected_item);

Answer 2

使用 SetItemState(0, LVIS_SELECTED, LVIS_SELECTED) 突出显示，使用 SetItemState(0, ~LVIS_SELECTED, LVIS_SELECTED) 取消突出显示。

Answer 3

只需设置属性->外观->始终显示选择为真

Answer 4

I think there is an undocumented feature of the SetItemState function where you can pass -1 as its nItem argument to make the function act on all items.

So, if you only want to select only one , I can suggest:

    SetItemState(-1, 0, LVIS_SELECTED);
    SetItemState(index, LVIS_SELECTED, LVIS_SELECTED);

UPDATE:

(after seeing http://www.verycomputer.com/417_11fcb075491b88c9_1.htm#p3 )

The SetItemState function sends the LVM_SETITEMSTATE message, and the nItem=-1 feature is documented on the message's reference documentation as its wParam argument.

If you wont set selected item in OnInitialDialog you mast use this code:

m_pSPSMapList->EnsureVisible(nItem, FALSE);
m_pSPSMapList->SetFocus();
m_pSPSMapList->SetItemState(nItem, LVIS_FOCUSED | LVIS_SELECTED, 
                                   LVIS_FOCUSED | LVIS_SELECTED);

return FALSE; // OnInitialDialog necessarily must return false

Answer 6

Provided that the index of the item fo be selected is w_nCurIdx , Use the following code

m_pSPSMapList.SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE, 0, LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT);
m_pSPSMapList.SetItemState(w_nCurIdx, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);
