Highlight Selected Report Columns

Hi all,

I am working on a report control for my application and have a couple features that I haven't been able to find a solution for yet:

1. When a user clicks on an item, highlight the corresponding column.  If you sort, the column will be highlighted, but in my control the sort must be disabled, so there is no highlight.

2. Allow the user to select multiple columns.  I know this is possible because the report sample allows this, but I can't figure out where this option is set, unless this also is a consequence of disabling sorting.

3. (would be nice, but not critical) Remove the selection box around the row and customize the background color.  I am able to turn off highlighting for the row with wndReport.SelectionEnable(FALSE) but the box still shows up.  I found an old forum topic which suggests the function to override is GetItemMetrics, which I did, but it's not getting called - where exactly should this be added?

TIA

Further update on item #1:

Able to paint a particular column using a custom CXTPReportPaintManager that overrides DrawColumnBackground, as such:

void CCustomReportPaintManager::DrawColumnBackground(CDC* pDC, CXTPReportColumn* pColumn, CRect rcColumn, BOOL& bColumnPressed, BOOL& bDraggingFromHeader, CXTPReportHeader* pHeader) {
    if (pColumn->GetIndex()==1){ // column
        CXTPReportRecords* rows = pColumn->GetControl()->GetRecords();
        int i;
        for (i=0; i < rows->GetCount(); i++) {
            CXTPReportRecord* r = pColumn->GetControl()->GetRecords()->GetAt(i);
            r->GetItem(pColumn)->SetBackgroundColor(RGB(140, 240, 255));
        }
        pColumn->SetAlignment(xtpColumnTextRight);
    } else {
        pColumn->SetAlignment(xtpColumnTextCenter);
    }
}

Still some work left in tracking which is the currently selected column, and haven't found anything for item #2, but hopefully this is of use to someone searching in the future :)
