Tips and Frequently Asked Questions

 Using balloons


- Only when theming is enabled in the project options, the balloon will be visible.

- If you reparent the grid, the balloon should only be enabled AFTER the final grid's parent is set.

- Balloon hints are an API from Microsoft Windows and this does not support HTML formatted text. This is a limitation of the Microsoft Windows balloon API.

- There is a limitation to the number of characters in a balloon. This is also a limitation of the Microsoft Windows balloon API that we cannot workaround. For a regular cell comment, there is no such length limitation.

- From TAdvStringGrid version v4.5, several new balloon notification capabilities have been added. See example 76: https://www.tmssoftware.com/site/asg76.asp

- When using AddBalloon& AddImageIdx on the same cell , the AddBalloon will not work. These 2 features are mutually exclusive, only one type per call can be added.

- When grid. Balloon.Enable = true, it will automatically show a balloon when a cell contains text, i.e. it will show the text of the cell in the balloon. To prevent this, add the following event handler:
procedure TForm4.AdvStringGrid1CellBalloon(Sender: TObject; ACol, ARow: Integer;
  var ATitle, AText: string; var AIcon: Integer);
begin
  if not advstringgrid1.HasBalloon(acol,arow) then
  begin
    atitle := '';
    atext := '';
  end;
end;

What our customers say

Thank you Mr. Fierens for your time and assistance. Just want to say your VCL Pack is fabulous.

- Mark Mihevc

Thank you for this superb tool collection!

- Henning Swiboda

Thanks for the effort to create the VCL grid goodies ! These chunks of outcome-oriented teaching-material are very useful. It's unbelievable how powerful the grid is when one knows how to unveil it's countless options...

- Feichtenschlager Thomas

I don''t know how I could have created and managed so many projects without the AdvStringGrid! And although there is already so much functionality in it I''m using my own derived version with automatic column widths, enhanced export to Excel (including text colors, backround colors, comments, merged cells and more), the possibility to fill in static data at design time and more. This often allows me to build a new tool in hours instead of days! Support is also great! Thanks.
