【ASP.NET】GridView中如何隔行显示数据？

Question

谁知道，GridView中如何隔行显示数据？
如图：当GridView数据循环到行业资讯4的时候，空一行，之后再接着显示，请问这样如何做到呢？请高手指教，谢谢！

我是这样写的，但不起作用，代码如下：

            DataSet dss = OperateDB.GetDataSet("select * from table", CommandType.Text, "table");

            DataTable dt=dss.Tables[0];
            if (dss.Tables[0].Rows.Count > 0)
            {

                for (int i = 0; i < dss.Tables[0].Rows.Count; i++)
                {
                    if (i == 3) //我想在第三行位置，插入一个空行
                    {

                        DataRow dr = dt.NewRow();
                        dt.Rows.Add(dr); 

                    }
                }
            }
            this.GridView.DataSource = dt;
            this.GridView.DataBind();

 

dt.Rows.InsertAt(dr, i); 添加到指定行可以了，但问题又来了，每行数据的前面有个“· ” 这样的标志，这是由模板列生成的，怎么样才能清除某一行的模板列呢？

Answer 1

你好！

这样做你很难维护，如果只是想达到显示更直观的目的可以考虑每 4 行换一种背景色来代替。

Answer 2

那么肖先生，我这个问题如果想解决的话，应该如何做呢？等待回复，感谢！

Answer 3

如果你是想插入控行，参考 KeFang Chen 版主在下面地址的回复

http://social.microsoft.com/Forums/zh-CN/295/thread/f14df01d-b724-42bd-9d89-ec649678e05f

如果是想使用每隔4行显示不同颜色这就需要你在 RowDataBound 事件中自己维护了。

如果还有其它地方不清楚，请具体说明我们再讨论。

Answer 4

你还可以使用Repeater或者ListView控件，比这个简单啊

 照前面的方法我做了写了一下((Label)this.zixun2.Rows[i].Cells[0].Controls[0]).Text = "";  运行时说索引超出最大范围，不理解。按照我写的应该是对的呀，HTML代码如下：

 <asp:GridView ID="zixun2" runat="server" Width="280px" AutoGenerateColumns="False"
                                                                                GridLines="None" ShowHeader="False" >
                                                                                <Columns>
                                                                                    <asp:TemplateField>
                                                                                        <ItemTemplate>
                                                                                            <asp:Label ID="dd" runat="server" >d</asp:Label>
                                                                                        </ItemTemplate>
                                                                                        <ItemStyle HorizontalAlign="Left" Width="15px" />
                                                                                    </asp:TemplateField>
                                                                                    <asp:HyperLinkField DataNavigateUrlFields="id" DataNavigateUrlFormatString="shownews.aspx?nid={0}"

                                                                                    </asp:HyperLinkField>
                                                                                    <asp:TemplateField>
                                                                                        <ItemTemplate>
                                                                                            <asp:Label ID="Label1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"time","{0:yyyy-MM-dd}")%>'></asp:Label>

                                                                                        <ItemStyle ForeColor="#756F63" HorizontalAlign="Right" />

                                                                                    <div style="width: 100%">
                                                                                        还没有数据</div>
                                                                                </EmptyDataTemplate>
                                                                            </asp:GridView>

 

((Label)this.zixun2.Rows[i].Cells[0].Controls[1]).Text = "";  而这个就是在第几行的第一个单元格中的第一个1个控件，找到后转变为LABLE，然后把它的text属性赋为空。因为Label是模板列所以控件Controls集合应该是第一项，本以为这样会成功，但还是出错，不知道我错在哪里？请大家帮我分析分析，谢谢！
