Can I create a ListView with dynamic GroupItemCount?

Question

I'm using the new ASP.Net ListView control to list database items that will be grouped together in sections based on one of their columns like so:

region1
    store1
    store2
    store3
region2
    store4
region3
    store5
    store6

Is this possible to do with the ListView's GroupItemTemplate? Every example I have seen uses a static number of items per group, which won't work for me. Am I misunderstanding the purpose of the GroupItem?

Answer 1

I haven't used GroupItemCount, but I have taken this example written up by Matt Berseth titled Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls and have grouped items by a key just like you want.

It involves using an outer and inner ListView control. Works great, give it a try.

Answer 2

I tried using GroupItemCount programmatically but it didn't give me the expected results.

I followed Otto's suggestion and implemented an outer and inner ListView control. This seems to be the best available solution.
