Versions applicable

The custom sort property for subforms is supported in both C5 and C6.

Sort type

1. Field-based - Auto-sort subform records based on a form field in ascending or descending order.
2. Custom - Allow users to sort the records in a custom order by effortlessly dragging and dropping the rows. 

1. Custom sorting can be used both in List and Grid-type subforms.
2. Using the custom sort property, users can manually reorder the row sequence of a subform, while adding and editing records. This functionality is best suited for use cases that go beyond field-based sorting and require the subform's fields to be sorted in a particular order.
   

Things to know

1. Currently, you can drag and drop up to 200 subform rows using the custom sort option. 
2. The custom sort property will be enabled only if a combination of records and subform rows in your form does not exceed 10,000. 
3. If your form has 10,000 records or if a subform field in your form has 10,000 rows, then this property will not be enabled for that field. 
4. Consider the following cases.
   
1. Case 1: Let's say your application has 500 records and each record has a subform field with 20 rows. 
   
2. Case 2: Let's say your application has 100 records and each record has a subform field with 100 rows.
   
3. The custom sort property will not be enabled in both the above cases since the 10,000 limit criteria for records/subform rows has been met.
   

Note: 

The 10,000 records limit is applicable for the following versions of Creator applications:  C5 applications (sandbox included) and C6 applications in which you haven't enabled environments.

Enable subform field sorting

1. Open the form builder.
2. Select the required subform field.
3. Navigate to Field Properties on the right.

2. Select your preferred Sorting Order - Ascending or Descending.

1. When accessing the report or editing the subform record, you can observe that the field-based sorting will be applied to the subform field.
   
2. When you add rows to your subform field, you can drag and drop the rows if you've chosen the custom sort option.
   

Note:

1. For composite fields, sorting should be done based on the subfield (for example First Name or Last Name for Name field).
2. Sorting cannot be done based on the following:
   
1. Encrypted fields
   
2. URL
   
3. Audio
   
4. Video
   
5. Users
6. Multi-selection fields like checkbox and drop down
   
7. Integration fields

Mobile properties

The sorting option and view type you've chosen for your subform fields in web browsers will automatically be applied to both mobile and tablet devices.

1. If you've chosen the field-based sorting option, subform records will be automatically sorted based on a form field in either ascending or descending order.
2. If you've chosen the custom option, your users can sort the records by manually dragging and dropping the rows in their preferred order.
