How to set visible of buttons in a templatefield to false

Hiiii once again all :) I have a minor problem again.... Does anyone know how to set visible of buttons in a template field to false if the userType(usertype table in database) is Admin? Example the gridview has 3 templatefields, and the last templatefield has 3 buttons, edit, delete and view. i want to set visible to false of Delete and Edit if the userType is Customer, and visible to true if userType is Admin. i have the sample code here

                                                    AutoGenerateColumns="false"
                            CssClass="ProductListing"
                            Width="100%">
                           
                           
                           
                           
                                No Announcements Available
                           
                           
                               
                                   
                                        <%# Eval("Title") %>
