Is it possible to connect to a PostGreSQL DB (let's say one creates a GraphQL API via Apollo, or alternatively the Progress ODATA adapter https://www.progress.com/odata ), since you seem to support ODATA),
and then do in-place edits, inserts of rows, and bulk upload?
Thank you for the update.1. You can edit DataGrid. Just turn on settings from editing. I suggest you consider using Batch mode though because even if you modify several rows, they will be updated one by one (several server calls). Refer to T296262: dxDataGrid - How to access each updated item in batch editing mode for more information.
2. We do not have features to create new SQL server tables. You need to create tables manually.
3. It is not possible to insert multiple rows from a clipboard. You can insert data only cell by cell.
Let me know if you have further questions.
