Unable to view data in New Form

Hi DAX Community,

I am trying to create a new Custom Sales Order Enquiry form, which must have 2 filters FromDateTime and ToDateTime. This filter must run on the SalesTable.createdDateTime field and retrieve the records from SalesTable.

May I know how can i achieve this?

What steps I took:'

I created the form, create the 2 filters, Created A new table TestTable with 3 fields: SalesId, Sales Name and Created Date Time and this TestTable is being used as a DataSource in the New Sales Order enquiry form.

I can see that the data is being inserted in TestTable but not refecting in the form's grid.

To try fixing this, i tried TestTable_ds.research(true); in the form after the insertion took place - But this didn't fetch me any expected outputs.
