Technical: D365 FO - Display data in a Grid in an extended form from a datasource that is a temp table(TableType = TempDB).

Hi Experts,
I have a situation, to display data from a datasource that is a temp table(TableType = TempDB) in a Grid on a fomr that is an extension of standard form. With standard filtering functionality supported on the grid.

The method - dataSource.setTmpData(), no longer seems there in D365.

Have been looking for an example, but no luck.

If you have example code, can you please share, its urgent.

Thanks in advance.
