    Posted: 24 March 2006 at 5:07am
I have a special column on a table where each record has a different background color for the column.  (Just like the colored flag status column in Outlook.)  When I select a row, the row turns gray to indicate the row is selected but it overwrites the background color on the special column.  Is there any way to specify the column to not turn gray when a row is selected.  I still need the other columns of the row to turn gray though.

Try to use GetItemMetrics() callback method. See ReportSample for Automatic Formatting option and CMessageRecord::GetItemMetrics() sample method.

I tried playing with the metrics but it only effected the non-selected items.  When I select a row, it still turns the entire row gray.

Hi,

Agree with you, selection colors will override any other colors set inside GetItemMetrics(). So far, the solution would be to change control's  PaintManager highlight colors on the moment of drawing this item.

Inside GetItemMetrics(), insert a piece of code like following:

if (pDrawArgs->pRow->IsSelected())
{
     pDrawArgs->pControl->GetPaintManager()->m_clrHighli ght = RGB(245, 245, 245);
     pDrawArgs->pControl->GetPaintManager()->m_clrHighli ghtText = RGB(80, 100, 225);
}
else
{
     pDrawArgs->pControl->GetPaintManager()->m_clrHighli ght =  pDrawArgs->pControl->GetPaintManager()->m_clrHighli ght.GetStandardColor();
     pDrawArgs->pControl->GetPaintManager()->m_clrHighli ghtText =  pDrawArgs->pControl->GetPaintManager()->m_clrHighli ghtText.GetStandardColor();
}

Almost the same. Inside _BeforeDrawRow() event handler:


If Row.Selected Then
    wndReportControl.PaintManager.HighlightBackColor = vbRed
Else
    wndReportControl.PaintManager.HighlightBackColor = -1
End If

That is very close to what I was looking for but it still changed the highlighted color for the entire row.  I did get it to work with the following modified code:


    If ((Row.Selected = True) And (Item.ToolTip = "Alias Color")) Then
        grdItems.PaintManager.HighlightBackColor = Item.BackColor
        grdItems.PaintManager.HighlightForeColor = Item.ForeColor
    Else
        grdItems.PaintManager.HighlightBackColor = -1
        grdItems.PaintManager.HighlightForeColor = -1
    End If


I was luckily able to use the Item.ToolTip field to identify the specific column that I did not want to be highlighted. 

I would like to suggest adding a property for a ReportColumn object such as "ShowHighlighted" so I could simply do something like:


Column.ShowHighlighted = False


in order to prevent item in that column from changing background and foreground colors when the row is selected.
