Scrolling a datagrid - Form

[mvillion]

Hi
I guess I am lazy because LC handles so many things up to now.

I have created a data grid form and the vertifcal scroll bar is visible but moving it up an down only slides the bar - the data in the grid does not slide with it.

I have looked through the tutorials and there was nothing I could see about this. The forum did have one entry with a large amount of code but that was from 2014. So I wondered whether things have moved on, or do I have a stack of code to write.

Thanks
Matt

Well, to be honest, I've never worked with Data Grids . . .

But, just now I set up a very simple one containing a simple list and I had absolutely no problem whatsoever with vertical scrolling.

Hi Yes. A data grid is easy to work with as a list.
If you switch it to 'Form' mode and things change.

Aye, well, the hale thing's awa wi the faeries as far as I can tell.

When I changed my "Gridlock" from a table to a form all my data became invisible
(although I could see it in the props palette),

and when I changed it back to a table the data did NOT reappear
(although I could see it in the props palette),

which is Utter Rubbish!

I think if you work with datagrids more you'll understand why this happens. Forms and table datagrids are very different animals. I wouldn't expect them to share content.

Hi all

An update.
I shut the computer down. Restarted everything and it is working now.
No idea.

I needed to take a Dogbert approach.

Might it not be a good thing then to have 2 icons on the tools.rev palette:

1. for a datagrid table, and

2. for a datagrid form,

because, if they really are quite different BEASTS . . . the current situation does
. . . err . . . give the impression they are varaints of the same thing and both "benign vegetarians".

OR . . . putting things another way . . .

when I change my datagrid over from table to form how do
I get the data I entered while the thing was in table form
to reappear in the form format?

Voodoo and/or prayer and lots of luck.

Seriously, you can't.

You will need to do some scripting and adjust the default handlers in the datagrid form. The list datagrid is fairly simple and self-contained, the form datagrid must be fully managed by script and the template has to be manualliy constructed. Look at some of the online lessons.

Bump!

Thank you dogbert! Just spent a wee while wondering why the scroll bar did very little. Quit and restart and all is well.
