< asp：BoundField DataField =  教职员名称 HeaderText =  教职员名称 /> 
< asp：BoundField DataField =   FacultyID HeaderText =   FacultyID /> 
< asp：TemplateField HeaderText =   1 >  
< itemtemplate> 
< asp：DropDownList ID =   DropDownList1 runat =   server AppendDataBoundItems =   true >  
< asp：ListItem Value =    -  1>  - 选择评分 -  
 
 < /   itemtemplate  >  
 
 
< asp：TemplateField HeaderText =   2 >  
< itemtemplate> 
< asp：DropDownList ID =   DropDownList2 runat =   server AppendDataBoundItems =   true >  
< asp：ListItem Value =    -  1>  - 选择评分 -  
 
 < /   itemtemplate  >  
 
 
< asp：TemplateField HeaderText =   3 >  
< itemtemplate> 
< asp：DropDownList ID =   DropDownList3 runat =   server AppendDataBoundItems =   true >  
< asp：ListItem Value =    -  1>  - 选择评分 -  
 
 < /   itemtemplate  >

                           onselectedindexchanged="gvfaculty_SelectedIndexChanged" Width="91px">

                          <asp:BoundField DataField="Faculty Name" HeaderText="Faculty Name" />
                          <asp:BoundField DataField="FacultyID" HeaderText="FacultyID" />
                          <asp:TemplateField HeaderText="1">
