C# - is it possible to arrange ComboBox Items from a to z?

问题

I have a very messy long items full of strings in a combobox, and it would be lovely to just sort it from a to z to make it easier to track. Is it possible?

回答1:

There are two possible ways that I could think of:

A) Use the WinForms Combobox `Sorted` Property

If you're using WinForms, you can use ComboBox.Sorted = true;

B) Manually Sort your List with `OrderBy`

If the data in your combo box comes from in a form of a list, use OrderBy to the List of data you are going to put in the ComboBox before setting it.

Here's an example:

var myList = new List<string>() {"q","w","e","r","t","y"};
var sorted = a.OrderBy(c => c).ToArray()
comboBox1.Items.AddRange(sorted);

turns out I can answer my own question, in Windows 8 C# app, ComboBox has Sort() properties that would simply arrange every items from a to z. Thanks.

first I did not populate my dropdown combobox directly like this

AppCombBox1.Items.Add(comboboxvalue);

but instead i populated a list with same data (done in loop in code, which is searching through ini file for values):

List<string> TempList = new List<string>();
TempList.Add(comboboxvalue);

after list is populated, I sort it and after that I fill dropdown combobox with sorted values.

    TempList.Sort();
    foreach (string ListValue in TempList)
    {
        AppCombBox1.Items.Add(ListValue);
    }

Just set the Sorted Property to True. It will sort the elements. I am fetching values from database and it works fine.
