Hi all

"extreme bubble-sort":

Example:

I have a listbox with let's say four columns. I want sort this list box. Ok, sounds ease, just click on the right header and that's it...

next step:

I wanna sort it with two or more sort-levels. Example

first priority: column 3
second priority: column 1
third priority: column 2

result:

a   b   a  d
a   c   a  e
b   a   a  d
b   b   a  d
a   b   b  f

Any Idea where to find such an example?

Cheers

Choli

Add an extra collumn that contains all the keys concatenated together.  Sort on that.

ok, my question (specially my example) was not exact enough... I want to be able to sort every level either ascending or descending, so the situation could be:

   column 3 ascending
   column 1 descending
   column 2 descending

another idea?

I don't think you're going to find much joy there.  Listboxes just aren't that sophisticated.  You're probably going to wind up doing something in code that allows the user to specify the column sequence and asc/desc, then sorting an array that way and then loading the list box from the sorted array.  It's a cheesy solution, but it will work.

Thanx Clothahump.....

I got another solution. I just don't use a listbox. Instead I use VSFlexGrid7 which has a "stable" sort over several sort actions.

I'll leave the question open. Probably s.o. has an answer anyway....

thanx and cheers

btw.... I use VSFlexGrid instead of a list box or another grid. VSFlexGrid has a stable sort order what is exactly what I'm looking for...
