Bengt,

You might want to look at pbInitialSelectionEnable. Must say I had mixed results with this property. I think you should not set the property before the grid is filled.

On top of that; Peter has right that grids load and unload data and what to do with rows that were selected. OTOH; who is going to select rows from a grid with so many candidates? You are better off with a view with two lists. One with the possible candidates and one with the selected ones. This way, on selection, you move whatever you want to remember from the list with candidates to the list with selected ones.
