C# select item of combobox by ID

I have this class

   class ComboboxValue
    {
        public int Id { get; private set; }
        public string Name { get; private set; }

        public ComboboxValue(int id, string name)
        {
            Id = id;
            Name = name;
        }

        public override string ToString()
        {
            return Name;
        }

    }

and I set my entries like this:

 var list = Funktionen.LoadCustomers();
        foreach (var item in list)
        {
            MyCombo.Properties.Items.Add(new ComboboxValue(item.ID, item.Name));
        }

In another function, I will set a item in my combobox by customerID. How can I do this? Btw. I´m using Devexpress.

Thank you.

To select item in ComboboxValue class :

comboBox1.SelectedItem = comboBox1.Items.Cast<ComboboxValue>()
    .Where(i => i.Name == dataGridView1.CurrentRow.Cells[5].Value.ToString()).Single();

Try MyCombo.SelectedItem = MyCombo.Items.SingleOrDefault(x => (x as ComboboxValue).Id == externalID)

To programmatically select a value for the combo, set the ComboBoxEdit.EditValue property. Here is some sample code:

ComboBoxEdit.EditValue = 2;  // select an item which ID = 2

Besides the Selected index you can use the SelectedItem property to select any item within the editor's item list. You need to assign an underlying data object to the SelectedItem property.

Alternatively, you can set its EditValue to '25' that is the ValueMember property value of the desirable item as shown in above example.

var item = MyCombo.Properties.Items.FirstOrDefault(i => i.ID == yoursearchIDhere);

item will be combobox item which you want to get. If you look for it or not, let me know and explain clearly please LoadCustomers() should return List also.
