Need to fetch checkbox value when it is de-selected or unchecked

You can use below code to achieve this.

load(
local!selectedBoxIDs,
local!uncheckedBoxId,
local!oldSelectedBoxIDs: tointeger(
{}
),
/*Array to hold all checked ids.*/
with(

a!checkboxField(

.......
value: local!selectedBoxIDs,
saveInto: {
local!selectedBoxIDs,
a!save(
local!uncheckedBoxId,
difference(
local!oldSelectedBoxIDs,
local!selectedBoxIDs
)
),
a!save(
local!oldSelectedBoxIDs,
save!value
)
}
)

)
)

Thanks!

What I understood is you are trying to save/store the value of deselected checkbox. The above solution should work in this case.

This is right. But I need to fetch value of particular checkbox which is unchecked.

The above code gives you exactly that. The value of the unchecked checkbox.

If you want a list of all unchecked checkboxes you may also use append() function (depending on what you actually need.)

Thanks!
