i tried put <asp:templatefield> , <asp:dropdownlist> i'm having error "type 'system.web.ui.webcontrols.boundfield' not have public property named 'templatefield' or 'dropdownlist'

the textbox , dropdownlist should appear when click edit button in gridview item list able edit output. thank yoou much.

template field tag not allowed inside boundfield tag, should tag separately example.

<asp:boundfield datafield="jobtitle" headerstyle-backcolor="#666666"   headertext="job title"itemstyle-height="10px" itemstyle-width="50px">                                     <headerstyle backcolor="#666666" />                                     <itemstyle width="50px" />  </asp:boundfield>   <asp:templatefield headertext = "column header" itemstyle-width="95px" headerstyle-horizontalalign="center"> <itemtemplate>  <asp:dropdownlist id="yourdroddown" runat="server">            <asp:listitem selected="true">item 1 </asp:listitem>          <asp:listitem>item 2</asp:listitem>        <asp:listitem>item 3</asp:listitem> </asp:dropdownlist> </itemtemplate>  </asp:templatefield>
