Index is getting refreshed after changing the page

Hello Shyam,

Thanks for your suggestion. Your suggestion actually worked for me, The datasubset which I was calling from the Parent interface has pagingInfo appended to it and that is why it was refreshing the index everytime(As you mentioned). I just passed the whole datasubset without any pagingInfo and its now working fine

This is default behavior. Selection will be per grid but the ri!Datasubset is per page. Meaning, when you switch to next/previous page, Appian will query DB with the updated paginginfo (startindex of the next page and the batchsize get updated automatically), so the Datasubset will only have data for that page.

So this

index(ri!Datasubset.data.c2,wherecontains(ri!selectedRows[fv!index],ri!datasubset.data.eid),{})

will only has data for the current page

I wouldn't recommend but you can solve this by getting data from DB for selected identities instead of the datasubset. Basically you will be querying DB everytime a selection is made and this WILL degrade performance.

Use the gridselection type to automatically save selection between pages. The selected value will be identifier of the datasubset
