Create Serial Number for subform rows
Requirement
Create serial numbers or auto-numbers for subform rows when a new row is added.
Use Case
In an employee management system, an employee can add
up to five
dependents.
It will be easy for the employees if the dependents added in the subform are numbered automatically.

Subform (Add Dependents)
|
D
ependents - You can add upto 5 Dependents.
|
Dependents
|
Multiple fields can be added to the
Add Employee
form. We have added a
smaller
number for brevity.
3. Now, let's
create a workflow
to disable the
S.No
field in the
Add Dependents
subform during the load of the
Add Employee
form.
4. Add the below
Deluge code in the editor:
- disable Dependents.S_No;
5.
Now, let's create a workflow to calculate the serial number for the subform rows.
6.
Add the below code in the Deluge editor:
- //Set the number of subform rows to 0
- recCount = input.Dependents.count();
- // Inform the employee that only 5 dependents can be added
- if( recCount == 5 )
- {
- alert "This is the last dependent you can add. Please note that if you want to add a dependent, you have to remove one.";
- }
- //Set the current row's S.No value to the recCount
- row.S_No =recCount;
When a new subform row is added, the
S.No
field gets populated.
See how it works
Points to Note
-
Auto-number fields are not allowed inside subforms, so that there is no confusions when subform records are inserted.
