Sort by Value

[Stuart Hemming]

Rather than sorting my listboxes by the Text property of the ListBoxItems, I want to use the Value property.

I understand that I'm going to have to do that server-side and I have no problem with that it's just that the following seems a lot of work...

public partial class HierarchyMaintenance : System.Web.UI.Page
{
    protected void ListBox_Transferred(object sender, RadListBoxTransferredEventArgs e)
    {
        e.DestinationListBox.Items.Sort(new ListBoxValueComparer());
    }

    public class ListBoxValueComparer : System.Collections.IComparer
    {
        int System.Collections.IComparer.Compare(Object x, Object y)
        {
            string xValue = (x as RadListBoxItem).Value;
            string yValue = (y as RadListBoxItem).Value;
            return Comparer.DefaultInvariant.Compare(xValue, yValue);
        }
    }
}

And if I want to sort by an attribute I would have to create a comparer for each one.

It would be nice to be just able to write something like ...

e.DestinationListBox.Items = 
e.DestinationListBox.Items.OrderBy(i=>i.Attributes["MyAttribute"]);

Or have I missed something?

Hi Stuart,

Yes, this would be a nice feature to add for RadListBox. We will consider implementing it.

If it get's added to PITS could you post a link here and I'll try drumming up a bit of support for it.
