How to get the value of a Enumeration Item?

Question

Hi,
I have the following enumeration:

 

Enum E1
{   LOW = 'L', 

   MEDIUM = 'M',

   HIGH = 'H'

}

 
I have loaded those values to a combo box, but how do i display the value of "MEDIUM" (I.E. M), when i select "MEDIUM" from the combo box?
TY in Advance
