有三种实现的方式,
第一种方式,直接在Aspx页面GridView模板列中.这种的缺点是到第二页分页时又重新开始了.
<Columns>
<asp:TemplateField HeaderText="序号" InsertVisible="False">
<ItemStyle HorizontalAlign="Center" /> <HeaderStyle HorizontalAlign="Center" Width="5%" /> <ItemTemplate> <%#Container.DataItemIndex+1%> </ItemTemplate></asp:TemplateField></Columns>
第二种方式分页时进行了计算,这样会累计向下加.<asp:TemplateField HeaderText="序号" InsertVisible="False">
<ItemStyle HorizontalAlign="Center" /> <HeaderStyle HorizontalAlign="Center" Width="5%" /> <ItemTemplate> <asp:Label ID="Label2" runat="server" Text='<%# this.MyListGridView.PageIndex * this.MyListGridView.PageSize + this.MyListGridView.Rows.Count + 1%>'/> </ItemTemplate> </asp:TemplateField> 第三种方式还有一种方式放在cs代码中,和第二种相似.<asp:BoundField HeaderText="序号" >
<ItemStyle HorizontalAlign="Center" /> <HeaderStyle HorizontalAlign="Center" Width="5%" /> </asp:BoundField> protected void myGridView_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowIndex != -1) { int indexID = this.myGridView.PageIndex * this.myGridView.PageSize + e.Row.RowIndex + 1; e.Row.Cells[0].Text = indexID.ToString(); } }第四种方法
双击GridView的OnRowDataBound事件;
在后台的GridView1_RowDataBound()方法添加代码,最后代码如下所示: protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { //如果是绑定数据行 //清清月儿 if (e.Row.RowType == DataControlRowType.DataRow) { 鼠标经过时,行背景色变 //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'"); 鼠标移出时,行背景色变 //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");当有编辑列时,避免出错,要加的RowState判断
//if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate) //{ // ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除:\"" + e.Row.Cells[1].Text + "\"吗?')"); //}}
if (e.Row.RowIndex != -1) { int id = e.Row.RowIndex + 1; e.Row.Cells[0].Text = id.ToString(); }}
注意这时最好把前台的第一列的表头该为“编号”,因为以前的第一列被“吃掉”了。
<asp:GridView ID="GridView1" runat="server" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound"> <FooterStyle BackColor="White" ForeColor="#000066" /> <Columns> <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" /> <asp:BoundField DataField="姓名" HeaderText="用户姓名" /> <asp:BoundField DataField="员工性别" HeaderText="性别" /> <asp:BoundField DataField="家庭住址" HeaderText="家庭住址" /> <asp:CommandField HeaderText="选择" ShowSelectButton="True" /> <asp:CommandField HeaderText="编辑" ShowEditButton="True" /> <asp:CommandField HeaderText="删除" ShowDeleteButton="True" /> </Columns> <RowStyle ForeColor="#000066" /> <SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" /> <HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" /> </asp:GridView>这里基本上介绍的已经够用了,详细试试;
Repeater自身就带有这个获取当前行号的属性,而无需程序员绑定这个行号,Container.ItemIndex 就可以获取了,见下示例:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate> 行号:<%#Container.ItemIndex %> </ItemTemplate></asp:Repeater>如果上面的示例中,Repeater已经绑定了数据,并且数据的至少为一笔记录,那么行号就会显示出来,行号从零开始,如果想改为从1开始,那么可以将以上的代码改为Container.ItemIndex + 1,见如下示例:
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate> 行号:<%#Container.ItemIndex + 1 %> </ItemTemplate></asp:Repeater>就可以了。
<asp:Repeater ID="Repeater1" runat="server"> <ItemTemplate> <%# Container.ItemIndex + 1%> <%# (Container as RepeaterItem).ItemIndex + 1%> </ItemTemplate></asp:Repeater>
赠送一个小技巧:
Repeater数据为空时提示暂无数据
<FooterTemplate> <asp:Label ID="lblEmpty" Text="暂无数据" runat="server" Visible='<%#bool.Parse((Repeater1.Items.Count==0).ToString())%>'></asp:Label> </FooterTemplate>
