Question

How can I select the item in the comboBox with key “02”?

public class GenericComboBox
{
    private string _key = string.Empty;
    private string _value = string.Empty;

    public string Key
    {
        get { return _key; }
        set { _key = value; }
    }

    public string Value
    {
        get { return _value; }
        set { _value = value; }
    }

    public GenericComboBox(string key, string value)
    {
        _key = key;
        _value = value;
    }
}

//Add data
IList<GenericComboBox> data = new List<GenericComboBox>();

data.Add(new GenericComboBox("01", "01 text"));
data.Add(new GenericComboBox("02", "02 text"));
data.Add(new GenericComboBox("03", "03 text"));

comboBox1.DataSource = data;
comboBox1.ValueMember = "Value";

//comboBox1.SelectItem With key equal "02"

Thank you.

.Net 2.0: (data needs to be a List not an IList for this one.)

    this.comboBox1.SelectedItem = data.Find(delegate(GenericComboBox gc) {return gc.Key == "02"; });

.Net 3.5:

    this.comboBox1.SelectedItem = data.First(gc => gc.Key == "02");
