Hi,

I am loading strings to ccombobox and i also want to change the dropdown background color of it.

dc->FillSolidRect(&rc, CustomColor);

I have added this code to overriding OnDrawItem method

It fills entire drop down with the custom color but the text previously added to combobox will not be shown.

How to make text visible after filling the combobox background color

Solution 1

Instead of overriding OnDrawItem you need to override OnCtlColor like this:

C++

HBRUSH CMyComboBox::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
    if (nCtlColor == CTLCOLOR_LISTBOX)
        pDC->SetBkColor(RGB(255, 0, 0));

    return CComboBox::OnCtlColor(pDC, pWnd, nCtlColor);
}

hmm.... i tried modifying to OnCtlColor. The method is firing but changes are not reflecting to the UI. Is any additional code required here
