Sort ListLox ListItems with LINQ?

Question

I am trying to sort items in a ListBox. However, after that the Item value gets the Item Text value. Any help would be appreciated.

lbxCustomers.DataSource = lbxCustomers.Items.Cast<ListItem>().Reverse().ToList(); lbxCustomers.DataBind(); 

Answer 1

Perhaps you should first save the list to a shared collection, and then sort it. Something like that:

 List<ListItem> list = new List<ListItem>(lbxCustomers.Items.Cast<ListItem>()); list = list.OrderBy(li => li.Text).ToList<ListItem>(); lbxCustomers.Items.Clear(); lbxCustomers.Items.AddRange(list.ToArray<ListItem>()); 

Answer 2

Try resetting the DisplayMember and ValueMember the Listbox after installing the DataSource. Many times, if the control is already bound and you set the DataSource again, it disables the DisplayMember / ValueMember properties.

Answer 3

Try sorting the list separately. In the next step, specify the value "Text" and "Data". Databind control.
