Looks like in the above snippet use case is to get data and show on the grid if that is case in the query entity or record entity it is suggested to use fv!paginginfo so that records will be feteched accordingly.

You could try updating just the identifiers parameter of the datasubset with the identifiers for the current page via a!update().

hi could modify code for pagingSaveInto as pagingSaveInto: a!save(local!pagingInfo, save!value), and rowHeader : 1 and check please just a try

The reason is..the code is already written and there are other changes I need to do if I change that to todatasubset(), because I can't set the identifiers by my own and it's taking the id automatically like 1,2,3. That will make lot of code change again. So I was thinking of a minimal code change but no major testing needed.Hope that makes sense.

it seems like you're doing a lot of work to manually recreate the output you'd get automatically just from calling todatasubset() on the original data set and paging info. I guess I'm unclear why.

Now I am doing something as below and it's working now

The change is in data and indentifier parameter in a!datasubset()

again - todatasubset() does this for you. a!dataSubset() does not.

Is there any easier way to get a range in appian for an array?

Well ... sure, just pick the first n items to put into the data.

It's vice-versa..actually ..batch size is 10 ; but the total data is 12

I can but the code already written earlier..and if I change that..lot of other changes needed as with todatasubset() , I am unable to play with the identifiers and it's taking like 1,2,3 automatically instead of real primaryley or the the id that I need..becaused based on the selected row many other functionalities already being designed..So thinking is there any way to do with current coding only by using a!datasubset()

RE: Pagination in todatasubset

Use todatasubset().

Your batchsize is greater than the number of rows that are available. Lets say you have 10 rows in the 1st page you are trying to fetch another 10 i.e 11-20 rows which are not available in the data.

As I am having pagination in my grid..how can I make it data to be changed dynamically based on pagination?

RE: Pagination in todatasubset

Stefan Helzle — Wed, 24 Jul 2024 15:01:35 GMT

When creating a data subset using a!datasubset(), you have to make sure that the number of items in "data" matches the batchsize parameter.

Please find the error screenshot along with the code snippet

I just put some portion of the code needed to debug this

a!localVariables(
local!paginInfo:a!pagingInfo(
startindex: 1,
batchSize: 10
),
local!mapDataSubset: a!dataSubset(
startIndex:local!paginInfo.startIndex,
batchSize:local!paginInfo.batchSize,
totalCount:count(index(ri!map,"abc",{})),
sort:a!sortInfo(
field:"abc",
ascending:true
),
data:ri!map,
identifiers:index(ri!map,"abc",{})
),
a!gridField(
label: "label",
labelPosition: "ABOVE",
data: local!mapDataSubset,
pagingSaveInto:local!paginInfo

)

Please share the code snippet of what you have configured and the error box screenshot if possible.

I do not fully understand. Can you share some code snippets explaining what you are doing?
