How to retrieve additional data for grid row to edit only if user want to edit certain row?
In other words:
- grid is defined with datasource with f.e. 4 fields,
- but with pressing edit row I want popup to retrieve 50 more fields for this row,
- BUT after pressing update I want grid to show updated data (with this 4 fields)
In other words:
- basic data for datasource for grid contain 4 fields/colums
- after clicking edit for row this datasource adds more fields to datasource for edit row.
I know I can at start retrieve all 54 fields and show only 4 of them in the grid and all of them in edit popup, but this might cause perfomance problem.
