is it not just cmbdescription.value
You have to convert the selected item to the object type that you are binding ie:

let say your object is Product and has the property named Description

so you convert like this

Product p = (Product)combobox.SelectedItem;


cmbDescription.Selection.Value.ToString() ;

hope this helps!
