Javascript validation for subgrid in a secondary tab

Posted on by M.Barimah

Hello Community,

I have a lead form that has multiple tabs, when I qualify a lead I trigger some javascript to run some validation on some field and verify that the information's are filled.

One of the things that I am trying to achieve, is to be able to see whether a user has created a record in a particular subgrid, by counting the number of records in the following way

formContext.getControl("grid").getGrid().getTotalRecordCount()

The problem that I am facing is that the result of this will always be 0 if I am not on the specific tab where the grid is because the grid has not loaded. I think this happens because dynamics loads data lazily.

How do I count the number of items in the subgrid without navigating to the specific tab, and select qualify?

Hi M.Barimah,

If your view in the Subgrid is unchangeable, you could directly query form the Dataverse by using retrieveMultipleRecords() methond(link:retrieveMultipleRecords (Client API reference) in model-driven apps - Power Apps | Microsoft Docs) with the same filter of your view.
