Setting up DataGrid Scroller
Hello, I am new to using merge software and was hoping I could get a little advice in getting the Merge DataGrid Scroller set up and working on my Livecode.
I am running Livecode Commercial 6.5. I have Droptools open. I have Merge Datagrid Scroller open. I have a new stack I created for testing. DataGrid Helper is also running if that makes a difference.
Here is what I did:
I noticed that nothing on the Merge Datagrid Scroller stack was clickable or drag-able, so I went to the application browser and copied the group "MergeDataGridScroller" into my blank stack. I then wrote a card script to populate the DG with 100 lines of text. I then set the dgData of the datagrid to my array. I then created two buttons, one to populate the datagrid and one to empty it. I went into the datagrid template and set the default text of field "label" to "default".
Here is what happened:
In development I will press the button that populates and 100 lines of emptiness will appear. The default text did not appear nor did the text that was entered by the script. The datagrid could still be scrolled by moving the scrollbar with the mouse for all 100 lines. When deployed to android it was the same. The scrollbar worked fine, there were 100 lines populated with emptiness. Only, there was no ability to scroll through the lines with touch swiping.
Any suggestions on what to do and why the datagrid scroller is hiding the text and not allowing the android device to scroll. I am also unfamiliar with droptools and am wondering if there is something specific that needed to be done with the droptools stack before copying the datagrid group over to my stack.
Attached is a zip file of the really simple stack I created.
Thanks in advance for your help to anyone reading this. I am super stoked to get this working for my project!

Re: Setting up DataGrid Scroller
Hi Will,
this has nothing to do with MergEXT!
You only need to set the TYPE of your datagrid to TABLE, which it obviously is!
And maybe add a new column, and everything should start to work correctly immediately

Re: Setting up DataGrid Scroller
Thanks for looking into this Klaus. You're the best!
I apologize if this is the wrong area of the forum. I just saw that there was another post about the merge datagrid scroller in this same forum so I thought this would be the right place. Where would you suggest I make a post on this topic if there were a next time?
Also, I tried your advice Klause. I can get the text to show up if I set the datagrid as a table. I don't really want a table. A table will work however because they are not too much different, (at least with a little bit of work). But either way, my main issue is still present. I notice that the datagrid does not scroll using touch swipe gestures on my android device.
I have not tried iOS. But I am pretty sure Monte included native Android functionality and a backup script if neither of them worked. So would you be able to look at the wrapping group in my stack or maybe my methods to see if there are any errors? That would be really cool.
(Also, is it normal to not be able to move or drag and drop anything on the Merge stack? It seems like you are supposed to by the way the instructions are worded.)
Any help would be much appreciated.
Thank you Klaus and fellow Livecoders!

Re: Setting up DataGrid Scroller
Hi Will
No idea why it does not update in the monent.
I usually script everything by hand, here a script for creating a scroller for a datagrid (card script):
Replace "DataGrid 1" with the name of your datagrid and you can copy/paste the script to your card

this is the correct place, only one part of your problem, the one I spotted immediately, was LC relatedWilliam Jamieson wrote:I apologize if this is the wrong area of the forum.

Unless you do not modify the ROW TEMPLATE they are basically the same, yes.William Jamieson wrote:Also, I tried your advice Klause. I can get the text to show up if I set the datagrid as a table.

I usually script everything by hand, here a script for creating a scroller for a datagrid (card script):
Code: Select all
local sScrollerID
## Create scroller now:
on opencard
create_scroller
end opencard
on closecard
delete_scroller
end closecard
command create_scroller
put "DataGrid 1" into tScrollerGroup
if the environment <> "mobile" then
exit create_scroller
end if
## Create native scroller object and save its ID in a local variable
MobileControlCreate "scroller"
put the result into sScrollerId
## RECT is the area on the card where the SCOLLER should do its work
MobileControlSet sScrollerId, "rect", (the rect of grp tScrollerGroup)
put the width of grp tScrollerGroup into tWidth
put the dgFormattedheight of grp tScrollerGroup into tHeight
set the dgvScroll of grp tScrollerGroup to 0
## WHAT part fo the datagrid shall be scrolled-> the complete datagrid
MobileControlSet sScrollerId, "contentRect", (0,0,tWidth,tHeight)
## Display SCROLLER
MobileControlSet sScrollerId, "visible", "true"
## the typical BUMP effect when you ge to the edge of the object
MobileControlSet sScrollerId, "canBounce", "true"
MobileControlSet sScrollerId, "pagingEnabled", "false"
MobileControlSet sScrollerId, "vIndicator", "false"
MobileControlSet sScrollerId, "borderStyle", "none"
MobileControlSet sScrollerId, "canScrollToTop", "false"
end create_scroller
## Will be sent when the user actually SCROLLs with his finger
on scrollerDidScroll OffsetX, OffsetY
lock screen
set the dgvScroll of grp "DataGrid 1" to OffsetY
unlock screen
end scrollerDidScroll
## REMOVE natove object when card closes!!!!!
command delete_scroller
if the environment <> "mobile" then
exit delete_scroller
end if
MobileControlDelete sScrollerId
end delete_scroller
No, sorry, I will not go through 500+ lines of other peoples code voluntarilyI have not tried iOS. But I am pretty sure Monte included native Android functionality and a backup script if neither of them worked. So would you be able to look at the wrapping group in my stack or maybe my methods to see if there are any errors? That would be really cool.

Re: Setting up DataGrid Scroller
Hi Will
@Klaus you will get very bumpy scrolling with that script. You need to wrap the dg in an extra group then expand it to it's full height then scroll the wrapper group. Use accelerated rendering and scrolling layer mode.
Cheers

I had a quick look at your stack and basically you need to learn how to work with a data grid and probably DGS and DropTools are confusing things at this point. My suggestion is to start here http://lessons.runrev.com/s/3527/m/data ... -data-grid and work through the lessons. DGS works best with forms rather than tables. For mobile tables I'd actually recommend the runrev planet table as the datagrid was never designed for mobile tables. Once you get the hang of the data grid then the DGS part is easyWilliam Jamieson wrote: In development I will press the button that populates and 100 lines of emptiness will appear.

Re: Setting up DataGrid Scroller
Hi Will,
It was a long time I'm not had a look to the forum...
Inside DGH we have ready to use scripts for adding an iOS scroller to a datagrid and for managing native fields when editing the datagrid cells. (auto-capitalization, auto-correction, selection point magnification are supported)
In DGH, go to the iOS topic and install the "iOS Scroller & Native Fields script".
Regards,
Zryip
