Hii...
I need to display a composite(eg: A editable graph or a editable table) inside a NatTable cell.
I used cell editor for that purpose and able to do that... but the problem is composite appears only after clicking on the cell.
Is there any way to display composite in the cell without any user interaction.

Thank you

That depends on your painter. Do you ensure to set the bounds of your control in the paintCell() method of your painter?

What do you mean with persisting selected cells? Persisting in terms of storing it in a file or persisting in terms of keeping the previous selected cells in case you are selecting others?

For persisting selection in a file you need to create and register a corresponding IPersistable. For keeping the selection and not to clear it on select operations you need to register custom commands or command handlers that always perform selections with a internally pressed CTRL key.

??? if you scroll it needs to be repainted, or how should otherwise the view be updated? NatTable is a completely painted control

I am creating composite over the nattable and displaying it inside the cell using control.setBounds(bounds) inside cellpainter method.
But when the table is scrolled the cell contents are not scrolling means to say they are fixed at a position.... please suggest a way .

I guess you need to update the bounds of the control on scrolling. If you are using a custom ICellPainter for this, you need to do this in paintCell()

Sorry, I don't understand what you are trying to do. Are you trying to add a control to a cell and scroll it out of the visible area? That won't work since NatTable is not able to deal with moving a Control that is not rendered by NatTable out of the visible area.
