试试这个code.problem是CommandName，因为你没有在你的LinkBut​​ton

提供的CommandName

<asp:TemplateField HeaderText="Update"> 
      <ItemTemplate> 
       <asp:LinkButton ID="link" runat="server" Text="Choose" CssClass="linkbutton" CommandName="Choose"></asp:LinkButton> 
      </ItemTemplate> 
    </asp:TemplateField>
