Hi.
I have my own GridDataSource for that, but I want to extend the data
fetched by the GridDataSource.
I can see the following options for that.
* lazily init reference data by using the objects return from
dataSource.getRowValue(0) to
dataSource.getRowValue(grid.getRowsPerPage() -1)
* add a listener to dataSource.prepare which initializes the reference data
For the first approach I couldn't find a proper page lifecycle hook to
do it and the second approach means lots of work.
Is there really no better approach?
Br,
Timo Westkämper

I assume that I can use Grid.getCurrentPage() and

Correct, but even better would be to implement your own GridDataSource
since then you can do all the data fetching and preperations in one
go. Your own GridDataSource forms the source @Parameter for the Grid.
Cheers,
