Is it possible to store multiple values in an attribute?

In my case I have a ListBox with SelectionMode=Multiple, where I want to be able to save and retrieve all selections easily. Is it possible to do something like below?

public List<int> Ids
{
get { return GetAttributeValue<List<int>>("Ids"); }

set { SetAttributeValue<List<int>>("Ids", value); }
}

Thank you in advance!

Never mind, I missed out that a GetAttributeValues method existed

Solution below seems to work fine.

public IList<int> Ids
{
    get { return (IList<int>)GetAttributeValues<int>("Ids"); }
    set { SetAttributeValue<int>("Ids", value); }
}

Hi,

Yes this is possible by calling SetAttributeValues like this:

List<int> list = new List<int>();
list.Add(1);
list.Add(2);
SetAttributeValues("IDs", list);

You can also do the same with complex values:

List<Blog> list = new List<Blog>();
list.Add(BlogHandler.GetBlog(1));
list.Add(BlogHandler.GetBlog(2));
SetAttributeValues("Blogs", list);
