DBCrossView Header Height

  OK, the problem appears to be that the header memo height is not calculated until the onprint event. Unfortunately, the position calculations for the subsequent rows are done way before this event - so the headers print correctly, but the subsequent rows print to follow the default height of the header.
  
  Fixed with a kludge in
  
  procedure TfrxCrossColumnHeader.CalcBounds;
  
  begin
  DoAdjust(Self);
  
  SetLength(LevelHeights, FLevelsCount + 1);
  
  Items := AllItems;
  
  // calculate height of each row
  for i := 0 to Items.Count - 1 do
  begin
  Item := Items;
  l := Item.Level;
  
  // cell headers always adjust the last level height
  if Item.FIsCellHeader then
  l := FLevelsCount
  // don't count total elemens unless they are on last level.
  // such elements will be adjusted later
  else if Item.IsTotal then
  if l <> FLevelsCount - 1 then continue;
  
  if Item.Memo.Height > Item.FSize.Y then
  Item.FSize.Y := Item.Memo.Height + (Item.Memo.GapY * 2) + (TFrxFrame(Item.Memo.Frame).ShadowWidth * 2) +
  (TFrxFrame(Item.Memo.Frame).Width * 2);
  
  if l >= 0 then
  if Item.FSize.Y > LevelHeights[l] then
  LevelHeights[l] := Item.FSize.Y;
  end;
  
  which works for me in this instance.
  
  Could someone from FR please provide a better fix?
  
  Thanks

  IMO it would be enough to add new CrossTab property MaxHeight / MinHeight (similar to MaxWidth / MinWidth).
  These new properties should apply not only to cells but to column headers as well.
  
  This would help to solve my problem too as I descripted in [topic="13107"]How to set Column Header height[/topic]
