Check Box in DBGrid?

Hi All,

I'm new to Delphi...

I have an access database which, when I open in Access, one of the fields (Boolean) appears as a checkbox. When I open the table in Delphi6, the field contains True or False. Is there any way I can get the DBGrid to show a checkbox instead?

Thanks,
Freerider.

All the code is basically doing is drawing a checkbox inside of any Boolean fields within a dbgrid. What exactly is it you don't understand about it? Anything specific, or just all of it?

The problem is my limited understanding of the structure of Delphi programming - I couldn't see from the example, how I could recreate it in my program (ie which controls I should put on the form).

It doesn't matter now, cos I took inthe's advice and used a DBCheckBox instead - I don't really need the DBGrid...

Thanks,
Freerider

HI, FreeRider,
All what you want you can do by yourself, it's not so difficult as it seems from the first sight.
You must put TCheckbox component on your from with DBGrid
and in the OnDrawColumnCell DBGrid event write the code
to place the CheckBox on that cell which is currently selected (with a width and a height equal to the corresponding Rect).
The rest is simple (to fill OnClick event of the CheckBox).
Sincerely,
Nestorua.
