Like DataList and Repeater, they add their own templates according to their needs, and the simple examples are as follows:
The front code is as follows:
?
<body> <form id="form1"runat="server"> <div> <asp:DataList ID="DataList1"runat="server"DataKeyField="ID"RepeatDirection="Horizontal"> <ItemTemplate> <div style="text-align: left; background-color: #99ffcc;"> ID:<asp:Label ID="IDLabel"runat="server"Text=‘<%# Eval("ID") %>‘></asp:Label><br /> Name:<asp:Label ID="Pro_NameLabel"runat="server"Text=‘<%# Eval("Name") %>‘></asp:Label><br /> Price:<asp:Label ID="Pro_PriceLabel"runat="server"Text=‘<%# Eval("Price") %>‘></asp:Label><br /> Introduce:<asp:Label ID="Pro_IntroduceLabel"runat="server"Text=‘<%# Eval("Introduce") %>‘></asp:Label><br /> </div> </ItemTemplate> </asp:DataList> 当前页：<asp:Label ID="lblCurrent"runat="server"Text="1"></asp:Label> 总页数：<asp:Label ID="lblTotal"runat="server"Text="Label"></asp:Label> <asp:LinkButton ID="lbtnFirst"runat="server"OnClick="lbtnFirst_Click">第一页</asp:LinkButton> <asp:LinkButton ID="lbntUp"runat="server"OnClick="lbntUp_Click">上一页</asp:LinkButton> <asp:LinkButton ID="lbtnDown"runat="server"OnClick="lbtnDown_Click">下一页</asp:LinkButton> <asp:LinkButton ID="lbtnLast"runat="server"OnClick="lbtnLast_Click">最后一页</asp:LinkButton> </div> </form></body> |
The background code is as follows:
?
protectedvoidPage_Load(objectsender, EventArgs e){ DataListBind();}privatevoidDataListBind(){ intcurrent_page = Convert.ToInt32(lblCurrent.Text); SqlConnection con = newSqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString); SqlDataAdapter oda = newSqlDataAdapter("select * from June_Pro", con); DataSet ds = newDataSet(); oda.Fill(ds); PagedDataSource ps = newPagedDataSource(); ps.DataSource = ds.Tables[0].DefaultView; ps.AllowPaging = true; ps.PageSize = 4; lblTotal.Text = ps.PageCount.ToString(); ps.CurrentPageIndex = current_page - 1; lbtnFirst.Enabled = true; lbntUp.Enabled = true; lbtnDown.Enabled = true; lbtnLast.Enabled = true; if(current_page == 1) { lbtnFirst.Enabled = false; lbntUp.Enabled = false; } if(current_page == Convert.ToInt32(lblTotal.Text)) { lbtnLast.Enabled = false; lbtnDown.Enabled = false; } DataList1.DataSource = ps; DataList1.DataBind();}protectedvoidlbtnFirst_Click(objectsender, EventArgs e){ lblCurrent.Text = "1"; DataListBind();}protectedvoidlbtnDown_Click(objectsender, EventArgs e){ lblCurrent.Text = (Convert.ToInt32(lblCurrent.Text) + 1).ToString(); DataListBind();}protectedvoidlbntUp_Click(objectsender, EventArgs e){ lblCurrent.Text = (Convert.ToInt32(lblCurrent.Text) - 1).ToString(); DataListBind();}protectedvoidlbtnLast_Click(objectsender, EventArgs e){ lblCurrent.Text = lblTotal.Text; DataListBind();} |
Running results such as:
Use of DataList + paging (RPM)
