What are you trying to load from? If you're trying to load the values from a database or an XML file, then you can use Databinding to bind the combobox to a data source, where you've added all of the choices in advance.

I'm trying to do this from XML exactly, any elaboration for this possible.
~Thanks

DataSet has simple and straightforward method.

DataSet ds=new DataSet();
ds.ReadXml("file.xml");
....

Use DataSource method to populates combobox control.
