Selectable Grid Layout

This can be achieved by reversing the selected items array, and saving the first index of the resultant array in the pagingInfo.

a!save(
local!pagingInfo.selected,
index(
reverse(
local!pagingInfo.selected
),
1
)
)

Thank you Srinaths, Tried to Implement the same for the following sail recipe. forum.appian.com/.../SAIL_Recipes.html ended with error "Invalid index (1) for null value of type List of Variant", changed the same adding a an if condition in a!save. could you please suggest us is this good one. Attached has the code what changed

Try with this variation on shrinaths suggestion:
a!save(
local!pagingInfo.selected,
index(
reverse(
local!pagingInfo.selected
),
1,
null()
)
)

This way you'll avoid getting errors when the local!pagingInfo (should really be gridSelection) is empty, ie no rows are selected.
