You can't, at least not in the way you're trying. The LookUpEdit, as the name implies, looks up its values in a DataSource, eg. a collection of objects. Therefore, to display the value 3 you need to have a list of objects that contains this value and set it as a DataSource for the control.

List<string> values = new List<string>();
values.Add("3");
lookUpEdit.Properties.DataSource = values;
lookUpEdit.EditValue = "3";

Maybe if you specify what are you trying to do, we can help you achieve that.
