Writing a calculated value to a CDT in an editable grid

Hi,

When you update the value on the textfield then the saveInto opetation is perform, In you case the textfield is readonly so no saveInto will perform. You can save the difference on ri!items[ri!index].current and ri!items[ri!index].Lastmonth field

a!save() will not get executed in readOnly fields. You should try to save the same value by other means.

As textField is readOnly and you are not editing the value so that its saveInto not get execute.
Use same expression " a!save(ri!itemstoken,append(ri!itemstoken,save!value))" in Submit buttons saveInto.

Since the value is read only, perform the expression on the button field.

Value expression executes while displaying. The save/saveinto gets executed only when something is changed in the associated field.

So, what you see on the UI is not being saved.

To test this out under the grid have a textfields displaying the CDT(s) to see how the values are being changed

a!textField(
    label: "ri!items",
    readonly: true,
    value: ri!items
)

Thanks .. The given expression is insde a  rule!UHC_showItemRowEach. I am calling the rule from an interface where i have the submit button . so i cannot get the same index value inside the button ( or can i ? ) 

 

   rows: a!applyComponents(
          function: rule!UHC_showItemRowEach(
            items: local!items,
            index: _,
            itemstoken: local!itemsToken
          ),
          array: if(
            or(
              isnull(
                local!items
              ),
              count(
                local!items
              ) < 1
            ),
            {},
            1 + enumerate(
              count(
                local!items
              )
            )
          ),

Hi,

You can save the ri!items[ri!index].difference on ri!items[ri!index].current and ri!items[ri!index].Lastmonth text field

Thank you Vinay for the idea .
