Hi

I am coloring each alternate row in a dbgrid with 2 different colors.  This works fine.  Please see my code below.  My problem is that when I select rows on the grid it does not show that it is selected.  All the "Allwaysshowselection" and "RowSelect" options are set to "true" so I don't think it is that.  Any ideas as to how I can show which rows are selected using the code below:

void __fastcall TfrmCardPrintSelection::dbgDLAuthoritiesDrawColumnCell(
                  TObject *Sender, const TRect &Rect, int DataCol, TColumn *Column,
                  TGridDrawState State)
{
      int l_i_OddOrEven = 0;

      l_i_OddOrEven = dbgDLAuthorities->DataSource->DataSet->RecNo % 2;

      if( l_i_OddOrEven == 0 )
      {
            dbgDLAuthorities->Canvas->Brush->Color = clSkyBlue;
            dbgDLAuthorities->Canvas->Font->Color = clWhite;
      }
      else
      {
            dbgDLAuthorities->Canvas->Brush->Color = clWhite;
            dbgDLAuthorities->Canvas->Font->Color = clBlack;
      }
      dbgDLAuthorities->DefaultDrawColumnCell( Rect, DataCol, Column, State );
}

You just need to add in a check so that you can color the selected row such that it will still show up with a decent contrast.  Depends on the look you are going for but often I find switching the brush color and the font color to invert the selected row shows up good.

So something like this,
  ....
    if( l_i_OddOrEven == 0 )
      {
          if(State.Contains(gdSelected) == true)
         {
             dbgDLAuthorities->Canvas->Brush->Color = clWhite;
             dbgDLAuthorities->Canvas->Font->Color = clSkyBlue;
          } else
           {
             dbgDLAuthorities->Canvas->Brush->Color = clSkyBlue;
             dbgDLAuthorities->Canvas->Font->Color = clWhite;
           }
      }
      else
      {
          if(State.Contains(gdSelected) == true)
         {
             dbgDLAuthorities->Canvas->Brush->Color = clBlack;
             dbgDLAuthorities->Canvas->Font->Color = clWhite;
          }else
          {
             dbgDLAuthorities->Canvas->Brush->Color = clWhite;
             dbgDLAuthorities->Canvas->Font->Color = clBlack;
           }
      }
 ....
