Field calculations

Datagrids are very powerful, and free, but take a bit of work to master. Go here:


http://lessons.runrev.com/m/datagrid



Download the manual. Make a few practice DG's. A datagrid is comprised of standard LC objects and behaviors. They have their own suite of commands and properties that are not listed in the dictionary.



And again, your issue with LC are those of a new user who expects to be proficient without paying dues. LC is the most forgiving program of its kind on the planet for that sort of thing, but as Jacque said, there is a minimum of experience and hours required before that can ever happen. Once you are moderately at ease, you will indeed find that your intuition and expectations are often satisfied by LC, as if by magic.



Your formatting issues are simple to fix. Show us what you did. We will advise what to change, and what you need to learn in that limited context. This will guide you in the future with the next 1000 issues that crop up as you learn how to drive.

Hi J. Landman Gay

That is truly a wealth of information at that link. If I am to learn about
any kind of app, and in the case of LiveCode the information is everywhere,
and you need to find it where every it is hidden. In many cases the
information like DataGrids is not available or it is tied to the purchase
of an additional product. That is what I found with DataGrids. I want to
learn more about a DataGrid because I am a database developer and it seemed
like a good control to know about. I reviewed the DataGrid Helper product
on the LC store and looked at the video on the developer site. But it was
selling their product not allowing the user to use the control as it was in
LC. I find it is best to understand the control rather than start using a
custom product to do the tasks. It is the same thing with MobGui where the
one of two reference books for LC uses MobGui for all of its descriptions
to manage controls.

A simple thing I am finding also is the dictionary in LC is not very good.
Yesterday after I got the wrinkles out of my math scripts, I needed to
format the fields with a money symbol and decimal spaces. The Format
command gave me an error when I used it in my math script. The dictionary
gives little in the way of script help to debug the reason why it did not
work. I am finding this true of many of the dictionary descriptions. Maybe
a developer will write a new dictionary stack for new users that includes
sample code like the example you have at your link.

Thank you for being so helpful

Thank you

Vaughn Clement
