Issue in editable grid bulk selection

I would assume you can build some conditionality into your Selection Save Into, in order to check whether the save target already contains some value, and instead of overwriting it, append to it...

Thanks for the response, Mike...

I have tried to append instead of override. It is appending the next page selected all IDs, but when I try to deselect any row, that is not happening. It is always being selected. 

I tried like this.

selectionValue: local!selectedIndices,
        selectionSaveInto: if(
          a!isNullOrEmpty(local!selectedIndices),
          a!save(
            local!selectedIndices,
            a!flatten(save!value)
          ),
          a!save(
            local!selectedIndices,
            append(
              local!selectedIndices,
              a!flatten(save!value)
            )
          )
        )

Hi ganeshg0004 

The issue is with the "Select All" functionality. When you select all values using it and then navigate to the next page and select all again, it overrides the previously selected values. However, this issue does not occur if you manually select each value one by one, move to the next page, and continue the same process — in that case, the select and deselect functionality works as expected.

I would suggest the following options to resolve this:

1. Build a custom "Select All" functionality.

2. Alternatively, change the selection style to ROW_HIGHLIGHT.

selectionValue: local!selectedIndices,
selectionSaveInto: a!save(
          local!selectedIndices,
          a!flatten(save!value)
        ),
selectionStyle: "ROW_HIGHLIGHT"

Thanks Vyshnavi, for the suggestion...

I have fixed this issue by applying a condition for "select all" and "deselect all" in the selection save into as per below

 selectionValue: local!selectedIndices,
        selectionSaveInto: a!save(
          local!selectedIndices,
          if(
            a!isNullOrEmpty(index(save!value,1,null)),
            difference(local!selectedIndices,local!gridData.data.id),
            if(
              length(wherecontains(local!gridData.data.id,tointeger(save!value)))=length(local!gridData.data),
              union(append(local!selectedIndices,a!flatten(save!value)),append(local!selectedIndices,a!flatten(save!value)))
              a!flatten(save!value)
            )
          )
        ),
