更改 MFC 中 CListCtrl 全列的背景颜色
原标题：Change Background color of full column of CListCtrl in MFC
Ive made a CListCtrl in Report View in MFC. I want to color the first column (the full column, not only those cells where an Item is) with a grey background.
How can I do this? Thank

The way you will implement this is color each cell of the first row individually. The code will look something like below, which basically a blue print but It should work (Note:I haven t test this for this post). You will have to use lplvcd->iSubItem and paint the first column of each row.
void MyList::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVCUSTOMDRAW* cd = reinterpret_cast(pNMHDR);
*pResult = CDRF_DODEFAULT;
switch( cd->nmcd.dwDrawStage)
{
case CDDS_PREPAINT:
*pResult = CDRF_NOTIFYITEMDRAW;
break;
case CDDS_ITEMPREPAINT:
{
int rowNumber = cd->nmcd.dwItemSpec;
bool highlightRow = (bool)GetItemData(rowNumber);
if (highlightRow)
{
COLORREF backgroundColor;
backgroundColor = RGB(255, 0, 0);
cd->clrTextBk = backgroundColor;
}
}
break;
case CDDS_SUBITEM | CDDS_ITEMPREPAINT:
{
// something like if(lplvcd->iSubItem == 0 ) to paint first column
lplvcd->clrText = RGB(0,0,255);
*pResult = CDRF_NEWFONT;
return;
}
default:
break;
}
}
