根据Eval()函数绑定的值,来显示GridView中的控件的方法

复制代码 代码如下:

<asp:TemplateField HeaderText="操作" ShowHeader="False">
                                <ItemTemplate>
                                <asp:LinkButton runat="server" CommandName="Tranfer" CommandArgument='<%#Eval("ARTICLE_ID")%>' Text='<%#Eval("BeTop") == "置顶" ? "取消置顶":"置顶" %>' OnCommand="RowCommand"></asp:LinkButton>
                               <asp:PlaceHolder  runat="server" Visible='<% #Eval("BeTop") == "置顶"%>'>
                                <asp:ImageButton runat="server" ImageUrl="~/pic/向上.jpg" CommandName="OrderUp"
                                        CommandArgument='<% #Eval("ARTICLE_ID") %>' OnCommand="RowCommand" />
                                    <asp:ImageButton runat="server" ImageUrl="~/pic/向下.jpg" CommandName="OrderDown"
                                        CommandArgument='<% #Eval("ARTICLE_ID") %>' OnCommand="RowCommand" />
                                     </asp:PlaceHolder>
                                </ItemTemplate>

                                <ItemStyle HorizontalAlign="Center"/>
                            </asp:TemplateField>

用<asp:PlaceHolder runat="server" Visible='<% #Eval("BeTop") == "置顶"%>'>
