Repeater控件绑定及分页
前言
学习牛腩的时候接触到Repeater控件，感觉很神奇。Repeater控件，DataList,Datagrid控件都能绑定数据库动态显示数据库等的内容。
Html代码
<head runat="server"><title>无标题页title>
head>
<body><form id="form1" runat="server"><div><h1>分页显示h1><p><asp:Label ID="Label1" runat="server" Text="当前页：">asp:Label><asp:Label ID="Label2" runat="server" Text="Label">asp:Label><asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="上一页" /><asp:Button ID="Button2" runat="server" Text="下一页" OnClick="Button2_Click" />p><asp:Panel ID="Panel1" runat="server" Height="224px" Width="503px"><asp:Repeater ID="Repeater1" runat="server"><ItemTemplate><tr><td><%# DataBinder.Eval(Container.DataItem,"LastName") %><%# DataBinder.Eval(Container.DataItem,"FirstName") %>td>tr> ItemTemplate><AlternatingItemTemplate><tr><td><font color="blue"><%# DataBinder.Eval(Container.DataItem,"LastName") %><%# DataBinder.Eval(Container.DataItem,"FirstName") %>td>tr> font> AlternatingItemTemplate><HeaderTemplate><h3>模板页眉h3><table border="1"><tr><td>员工名字td>tr>HeaderTemplate><FooterTemplate><h3>模板页脚h3>table>FooterTemplate>asp:Repeater>asp:Panel>div>form>
body>后台代码
public partial class repeaterControl : System.Web.UI.Page
{protected void Page_Load(object sender, EventArgs e){//第一次登录if (!this.IsPostBack){this.Label2.Text = "1";this.dataBindToRepeater();}}private void dataBindToRepeater(){int curPage = Convert.ToInt32(this.Label2.Text);SqlConnection con = DB.createCon();SqlDataAdapter sda = new SqlDataAdapter();sda.SelectCommand = new SqlCommand("select * from employees", con);DataSet ds = new DataSet();sda.Fill(ds, "emp");//分页用pageddatasourceSystem.Web.UI.WebControls.PagedDataSource ps = new PagedDataSource();ps.DataSource = ds.Tables["emp"].DefaultView;ps.AllowPaging = true;ps.PageSize = 3;ps.CurrentPageIndex = curPage - 1;this.Button1.Enabled = true;this.Button2.Enabled = true;if (curPage == 1){this.Button1.Enabled = false;}if (curPage == ps.PageCount){this.Button2.Enabled = false;}this.Repeater1.DataSource = ps;this.Repeater1.DataBind();}//上一页按钮单击protected void Button1_Click(object sender, EventArgs e){this.Label2.Text = Convert.ToString((Convert.ToInt32(this.Label2.Text)) - 1);this.dataBindToRepeater();}//下一页按钮单击protected void Button2_Click(object sender, EventArgs e){this.Label2.Text = Convert.ToString((Convert.ToInt32(this.Label2.Text)) + 1);this.dataBindToRepeater();}
}
结语
这几天主要学了一些asp.net中的控件：内置控件，复杂控件（广告控件和日历控件），验证控件和列表控件。不知道该如何总结，学的也是囫囵吞枣，还是应该找几个重点的例子敲一敲，实践实践。
