API enhancement suggestion: ListGridField.setSort(SortSpecifier[] sortSpecifiers)

[Blama]

Hi Isomorphic,

as far as I know sorting in a ListGrid for paged SQL-data can happen either by the ValueField or the DisplayField (depending on the setSortByDisplayField(boolean)-setting on the ListGridField).

Could you add something like setSort(SortSpecifier[] sortSpecifiers) to ListGridField which should have the following effect:

When not all data loaded (=paged):
a) Sort ListGrid one column with ListGridField.setSort(SortSpecifier[]):
End SQL with "order by SortSpecifier[0], SortSpecifier[1]..."

b) Sort ListGrid by two columns, both with ListGridField.setSort(SortSpecifier[]):
End SQL with "order by SortSpecifier[0][0], SortSpecifier[0][1]..., SortSpecifier[1][0], SortSpecifier[1][1]..."


When all data loaded (=local sort, not paged):
a) setSortNormalizer not used: as above

b) setSortNormalizer used: use setSortNormalizer logic

Thanks,
Blama

You wouldn't want to do this. Loading the last page of the dataset would unexpectedly scramble the order of the rows.

Hi Isomorphic,

thanks for your reply. I rephrased the question a little bit and added a use-case. It is in thread http://forums.smartclient.com/showth...7287#post97287.
