  • Repeater 的使用

    <HeaderTemplate></HeaderTemplate>  头模板——在加载开始执行一遍

    <FooterTemplate></FooterTemplate>  脚模板——有多少条数据,执行多少遍

    <ItemTemplate></ItemTemplate>  项模板——在加载最后执行一遍

    <AlternatingItemTemplate></AlternatingItemTemplate>  交替展示模板

    1. 纯HTML+css+js制作
    2. 添加Repeater控件,将数据绑定展示

    例子:

    以China表为例数据展示:

    <body>
        <form id="form1" runat="server">
            <asp:Repeater ID="Repeater1" runat="server">
    <HeaderTemplate>
    <table style="background-color: navy; text-align: center;">
                        <tr style="color: white; padding: 10px;">
                            <td>区域编号</td>
                            <td>区域名称</td>
                            <td>区域父级编号</td>
                        </tr>
    </HeaderTemplate>
    <ItemTemplate> 
     <tr style="background-color: #e0e0e0;">
                        <td><%#Eval("AreaCode") %></td>
                        <td><%#Eval("AreaName") %></td>
                        <td><%#Eval("ParentAreaCode") %></td>
                    </tr>
    </ItemTemplate>
    <FooterTemplate>
                    </table>
                </FooterTemplate>
     </asp:Repeater>
        </form>
    </body>

    .cs代码

    //绑定数据
    if (!IsPostBack)
            {
                Repeater1.DataSource = new ChinaStatesData().Select("0001");
                Repeater1.DataBind();
            
            }

    China实体类

    public class China
    {
        public China()
        {
            
        }
        private string code;
    
        public string Code
        {
            get { return code; }
            set { code = value; }
        }
        private string name;
    
        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        private string prentcode;
    
        public string Prentcode
        {
            get { return prentcode; }
            set { prentcode = value; }
        }
    }

    China数据操作类

    public class ChinaData
    {
        SqlConnection conn = null;
        SqlCommand cmd = null;
        public ChinaData()
        {
            conn = new SqlConnection("server=.;database=mydb;user=sa;pwd=123");
            cmd = conn.CreateCommand();
        }
        public List<China> Select(string pcode)
        {
            cmd.CommandText = "select * from ChinaStates where ParentAreaCode=@pcode";
            cmd.Parameters.Clear();
            cmd.Parameters.AddWithValue("@pcode", pcode);
    
            conn.Open();
    
            SqlDataReader dr = cmd.ExecuteReader();
    
            List<China> list = new List<China>();
    
            if (dr.HasRows)
            {
                while (dr.Read())
                {
                    China data = new China();
                    data.Code = dr[0].ToString();
                    data.Name = dr[1].ToString();
                    data.Prentcode = dr[2].ToString();
    
                    list.Add(data);
                }
            }
    
            conn.Close();
    
            return list;
        }
    }

    ------------------------------------------------------------------------------

    以Users表作数据展示并作库存预警光棒效果:

    <body>
        <form id="form1" runat="server">
            <asp:Repeater ID="Repeater1" runat="server">
                <HeaderTemplate>
                    <table>
                        <tr>
                            <td>用户名</td>

                            <td>生日</td>
                            <td>民族</td>
                       </tr>
                </HeaderTemplate>
                <ItemTemplate>
                    <tr>
                    <td><%#Eval("UserName") %></td>

                        </tr>
                </ItemTemplate>
                <FooterTemplate></table>
    
                </FooterTemplate>
            </asp:Repeater>
        </form>
    </body>

    {
        SqlConnection conn = null;
        SqlCommand cmd = null;
        public UserDA()
        {

            conn.Close();
    
            return list;
        }
    
    }

    Nation实体类:

    public class Nation
    {
        public Nation()
        {
            
        }
        private string _NationCode;

                name = dr[0].ToString();
                
    
            }
    
            conn.Close();
            return name;
        }
    }

    数据绑定

    if (!IsPostBack)
            {
                Repeater1.DataSource = new UserDA().select();
                Repeater1.DataBind();
    
            }

     -------------------------------------------------------------------------------

    库存预警:

    <ItemTemplate>
                    <tr class="tr_Item" style="<%#Eval("Red")%>">//满足条件改变样式
                        <td><%#Eval("UserName") %></td>
                        <td><%#Eval("PassWord") %></td>
                        <td><%#Eval("NickName") %></td>
                        <td><%#Eval("SexStr") %></td>
                        <td><%#Eval("BirthdayStr") %></td>
                        <td><%#Eval("Age") %></td>
                        <td><%#Eval("NationName") %></td>
                    </tr>
                </ItemTemplate>

    Users实体类,通过扩展属性

     public string Age
        {
            get { return (DateTime.Now.Year - this._Birthday.Year).ToString(); }
        }
    
        public string Red
        {
            get
            {
                string end = "";
                if (Convert.ToInt32(Age) >= 16)
                {
                    end = "background-color:red;";
                }
                return end;
            }
        }

    光棒效果——鼠标移入移出颜色改变

    <style type="text/css">
            #tb1 {
                 100%;
                background-color: navy;
                text-align: center;
            }
    
            #tr_head {
                color: white;
            }
    
            .tr_Item {
                background-color: white;
            }
    
            .tr_Item2 {
                background-color: #e0e0e0;
            }
        </style>
        <script type="text/javascript">
            window.onload = function () {
                var items = document.getElementsByClassName("tr_Item");
                var oldColor = "";//用来记录原来的颜色
                for (var i = 0; i < items.length; i++) {
                    items[i].onmouseover = function () {
                        oldColor = this.style.backgroundColor;
                        this.style.backgroundColor = "yellow";
                    };
                    items[i].onmouseout = function () {
                        this.style.backgroundColor = oldColor;
                    };
    
                }
    
    
            };
        </script>
