I really don't like multipick listboxes because the are "user fragile" one little misclick and they've potentially lost all of the rest of the work they've done picking items elsewhere in the list. Using a checkbox in a grid avoids this.

Hi David,

I gave some thoughts into this interface problem, I also discussed it here and with my colleague, and the mover type interface seems to be the best from the user's perspective.

For this particular application I'm working right now, I need to have an ability to "save and restore" selection. In other words, when user navigate from record to record on the parent table, List with selected items should display towns, which were selected for this region.

So, the ideal mover, which I have in mind, should work with any type of Record Source (array, cursors, values, doesn't matter), should allow to work with multiple columns (AFAIK, these mover classes work with only one dimension) and allow to pre-populate the second list based on entries in the table. It also should have resize capability and drag and drop. Ideally it would allow to sort by clicking on the header (yes, I'm talking in terms of Cetin's multiselect grid) and have a re-order buttons on the left.

_FFC _Mover class seems to be over-complicated, too deep in class hierarchy, doesn't have enough comments, etc.

Our own class is very primitive and I believe, is only oriented on values as a RowSource.

So I'm seeking for something flexible and quite simple for my particular needs.

My manager just came to my desk and told me, that the multiselect grid would be sufficient here and since I already used this control in another application and it worked here buitifly, I don't need to re-invent the wheel and would use it instead.

So, I'm going to proceed in this direction.


>>I was thinking about this problem, and it seems to me, it could be solved by using two cursors with additional lSelected flag field. But I don't want to reinvent the wheel. I looked into FoxyClasses example and I like it, but it's not the final version, I suppose.
If it's not broken, fix it until it is.
