Hello All,

I have a group containing fields I use to filter a DataGrid object and wish to scroll them simultaneously when a user scrolls horizontally in the DataGrid.

So within the script of the DataGrid I wished to intercept the horizontal scrolling event, then similarly scroll the filter field group before passing the horizontal scroll event in the DataGrid.

I figured in the script of the DataGrid something like:
, but that isn't it.

I can manually do it from a button using:
, which proves the concept - however I need intercept the event when it happens.

Any assistance greatly appreciated.

Kind regards, Andrew

Hi Andrew,
Not quite sure what you're after, but i'm thinking it's something like this:
Look up scrollBarDrag in the dictionary. It gets sent to flds, grps, sbs when they're scrolled. You might need a pass scrollBarDrag with the above if you want the scrolled fld/grp (the one that sends the message) to scroll--not sure about that.

scrollBarDrag newPos

...is a message sent by the scrolled object so you can use it to do whatever you want i.e.
where doStuff is a function or procedure defined higher up the message path.

Hello all,

A solution provided by Zryip The Slug via the LiveCode Developer List:

To intercept horizontal scrolling in the DataGrid and to similarly scroll another group, in the script of the DataGrid add the following handler:
I hope that assists someone else.

Kind regards, Andrew

Thanks Steve,

I did try that, however it seems the DataGrid has it's own custom properties in respect of scrollbars.

Zryip corrected my earlier attempt at coding against the datagrid's custom properties.

Thanks again for posting. Steve.

Kind regards, Andrew

Apologies Andrew, I didn't know what a datagrid was (just looked it up). In fact I've fairly recently made a database app from scratch with similarly scroll-able, user-resizeable column flds--sheesh, I wish I'd known. (At least I can set the scrollwidths).
