Preserve Selection On Sorting [message #1699439] Wed, 24 June 2015 10:52 Go to next message

Suppose row 1 is selected and I sort the table and row 1 moves to position 5. But in table row 1 remains selected. Ideally old row 1 (new row 5) which is at position 5 should be selected.

What I do is save the selected objects before sorting and after sorting is done I select the same objects. Is that the correct approach?? Secondly, I want that in this case selection event shouldn't be fired because there is no change in selection.. is there any way of doing this?

That depends on your selection model. If you have row selection only, the RowSelectionModel should do that job already. If you don't have row selection you can use the PreserveSelectionModel to do that job for you. But you need to provide some information about identifying a row object uniquely to make it work via IRowIdAccessor.

There should be already some forum posts regarding that requirement.
