Something seems to have changed in the datagrid code, because I have
an old iOS device with a version of my software from over a year ago
and it scrolls fine so I feel like the issue is with my scroller and
DG2 (this stack pre-dates that change).
I tried Ralph's suggestion of adding 20px, b

Now that you mention this, I see the same issue with 2 of my apps in the iOS
store that were built using LC 9.5. There is one item just "past" the bottom
of the datagrid that you can only see if you swipe be
nd to last item.
Seems more like this is an issue with the scroller than the datagrid itself.

Hello
When I have datagrid display weirdness I do a couple things. First, I get the
dgText of the datagrid to see if there isn't unexpected data there. I will also
get the dgData to see if there aren't off keys. Once I had a bug in my code
that put a key of 0 with an empty value. It didn't display, bu
Just tested here with a table style DG. Works fine LC 9.5 MacOS 10.14.6.

Hello,
I have a problem with a datagrid. I cannot see the last couple of rows
when scrolling. For instance if you have 100 lines and scroll to the bottom
of the grid you only get up to 98. If you "hold" the scroll by forcing the
scroll to go to the bottom you can see lines 99 and 100 but be

compatibility (smooth scrolling is important, but not at the cost of
the app not even launching).

I guess I have abandon DG and go for with a manually built,
all-controls-on-the-same-front group, method.
Unless HQ can give us a head up as to when 9.1 will be released?

I agree. There has been a very significant deterioration in datagrid
scrolling performance since DG2 and LC9 were introduced. Based on feedback
from user testing we have delayed release of an important iOS app update
because DG scrolling was perceived to be unacceptably slow and visually
jerky
There were deeper engine changes to finish the accelerated rendering updates
required to fully support DG2. I think that is scheduled for 9.1 now.
Thanks,
Brian

Scrolling the Datagrid on mobile is "terrible" (jerky, pixel by pixel)
I thought this was fixed in Datagrid2?
Maybe that hasn't been released?

Dear Swami,
Mobile scrollers should be natively added by the dg2 library when the stack
is executed inside a mobile device context. I've seen the corresponding
portion of code inside the dg2 library.

I am slowly getting up to speed with datagrid, I understand structure, the
scripts of the row group, can instantiate data etc.
But, am I missing something?

You can get/put data from/into the grid one row at a time without needing to

Same remark than Mike, James and Jacque. When you have to change the value
of each row, populating the datagrid with a new data, seems to be the
better way to go.
Now for helping you with datagrids, I think you have to understand 2
importants concepts about datagrids:

I was thinking the same thing. I think the critical distinction is that
datagrids are primarily display mechanisms, not really intended to be read
directly. It's much easier to parse the original input data than to try to
traverse the grid itself, which uses some tricks to appear as a continuous
I am a little lost here as to why this is a DG question as such.
Certainly being able to dynamically fill data within a row is a great UI
feature when the user is directly interacting with a row.
But it seems you wish to completely fill particular values in all the rows from
outside the DG.
In th
My question is why use the button? Loop through the data in the grid and make
the tsnet call manually for each line. If the button is calling a script
outside of the DG, then you can use the same call. Then you don’t have to do
any of those things to figure out the name of the row group.

Here's an odd one: Scrolling a datagrid down on an alternate monitor goes

I am sure there are some speed up tricks for the DataGrid but remember that
the DataGrid is written in Livecode (just in time compiled) with multiple
elements and NSTableview would be binary. Apples and Oranges.

I have a DataGrid with 8 columns and 20 rows being fed by a sqlite database.
Is it possible to improve the scrolling of the DataGrid which I find stutters
