[RESOLVED] Coloring header row of CListCtrl C++

I have class MyClistCtrl derived from CListCtrl. I want to do two things:
1. Show only horizontal grid lines (I tried LVS_EX_GRIDLINES ,but this displays both horizontal as well as Vertical grid lines)

2. Change background color of header row,it is of gray color(system color),i want it to be white.I read several post and codes but nothing helped so please if anyone from Scratch can tell me with Code how to achieve that

But the Vertical grid lines are drawn by default. isn't it?

Have a look at this thread.

No no no..confusion.
You are right vertical grid lines are drawn by default but my requirement is i only want horizontal grid lines not both horizontal and vertical grid lines..

You may want to create your own user defined control. :rolleyes:

Means there is nothing like LVS_ something which can only draw horizontal gridlines,if so please can you help me with code snippet of user defined control you are talking about which can help me in achieving this.

Sorry! I never needed such a control... So try to google for that. :)

I did googled but no success...nothing worth found

sorry... :sick:

Can you please tell how and where WM_DRAWITEM should be called...and where is m_ HeaderCtrl declared?

See:
CListCtrl::GetHeaderCtrl
Header Control and List Control

What about WM_DRAWITEM

And plz help me with correct code because i have read all this CListCtrl::GetHeaderCtrl and Header Control stuff but couldn't able to implement it in a successful way
That's why asking for urgent help

Please, post your real code that compiles! not just a pseudo code.
And use the proper code indentations!

This is a real code and compiling at my end..

Then where and how is this method

Code:

---

void IEHeaderCtrl::
DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)

---

declared?

See this, although already posted above..

Code:

---

class IEHeaderCtrl : public CHeaderCtrl
{
public:
    IEHeaderCtrl();

protected:
    afx_msg virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
    DECLARE_MESSAGE_MAP()
}

Well, there is

Code:

---

...
afx_msg virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
...

---

, not the

Code:

---

DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)

---

Not getting what else you want.see the code below(already posted) which is having definition of DrawItem

Code:

---

BEGIN_MESSAGE_MAP(IEHeaderCtrl, CHeaderCtrl)
END_MESSAGE_MAP

void IEHeaderCtrl::DawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
    HDITEM hdi;
    CBrush brush(RGB(255, 0, 0));
    CString csBuffer;
    CRect rectFrame(lpDrawItemStruct->rcItem);

    ZeroMemory(&hdi, sizeof(HDITEM));
    hdi.mask = HDI_TEXT;

    LPTSTR pBuf= csBuffer.GetBufferSetLength(MAX_PATH);

    hdi.mask = HDI_TEXT;
    hdi.pszText = pBuf;
    hdi.cchTextMax = MAX_PATH;
    GetItem(lpDrawItemStruct->itemID, &hdi);
    csBuffer.ReleaseBuffer();

    CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);

    pDC->FillRect(rectFrame, &brush);
    pDC->SetTextColor(RGB(255, 255, 255));

There is no "definition of DrawItem".
There is a definition of DawItem. :rolleyes:

Oohhh Victor.i spelled it wrong here but at my wnd its DrawItem only
.Sorry ,plz assume it as DrawItem and tell the solution

Again: post your real code.
Why don't you want just copy/paste the code from your IDE?
Why do you ignore code indentation (or you remove it before sending a post?)

Code tags and formatting please. That mess is unreadable.

Did you debug your code? Is this DawItem (or DrawItem) called?

And BTW, do you set the ownerdraw flag to the header control items? See the Owner-Drawn Header Controls section in MSDN

Resolved..Thankyou

Could you share your solution?

Derive your own class from CListCtrl.
Derive your own class from CHeaderCtrl.
Replace the standard CListCtrl header with yours.
Use custom drawing for the header control.
In derived CListCtrl

Code:

---

void MyListCtrl::PreSubclassWindow()
    {
    // TODO: Add your specialized code here and/or call the base class
    CHeaderCtrl* pHeader = NULL;
    pHeader = GetHeaderCtrl();
    if (pHeader != NULL)
        {
        VERIFY(m_HeaderCtrl.SubclassWindow(pHeader->m_hWnd)); // m_HeaderCtrl is the new wrapper object
        }

    CListCtrl::PreSubclassWindow();
    }

---

In the headerCtrl class

Code:

---

void MyHeader::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
    {
    LPNMCUSTOMDRAW pNMCD = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR);
    // TODO: Add your control notification handler code here
    *pResult = CDRF_DODEFAULT;

    if (pNMCD->dwDrawStage == CDDS_PREPAINT)
        {
        CDC* pDC = CDC::FromHandle(pNMCD->hdc);
        CRect rect(0, 0, 0, 0);
        GetClientRect(&rect);
        pDC->FillSolidRect(&rect, RGB(255, 0, 0));

        *pResult = CDRF_NOTIFYITEMDRAW;
        }
    else if (pNMCD->dwDrawStage == CDDS_ITEMPREPAINT)
        {
        HDITEM hditem;
        TCHAR buffer[MAX_PATH] = { 0 };
        SecureZeroMemory(&hditem, sizeof(HDITEM));
        hditem.mask = HDI_TEXT;
        hditem.pszText = buffer;
        hditem.cchTextMax = MAX_PATH;
        GetItem(pNMCD->dwItemSpec, &hditem);
        CDC* pDC = CDC::FromHandle(pNMCD->hdc);
        pDC->SetTextColor(RGB(0, 0, 0));
        pDC->SetBkColor(RGB(255, 0, 0));
        CString str(buffer);
        pDC->DrawText(str, CRect(pNMCD->rc), DT_VCENTER | DT_LEFT);
        *pResult = CDRF_SKIPDEFAULT;
        }
    }
