本演示中,我们实现这个Repeater控件数据导出Excel的功能。 复制代码 代码如下: Imports Microsoft.VisualBasic Namespace Insus.NET Public Class Catalog Private _ID As Integer Private _Name As String Public Property ID As Integer Get Return _ID End Get Set(value As Integer) _ID = value End Set End Property Public Property Name As String Get Return _Name End Get Set(value As String) _Name = value End Set End Property End Class End Namespace 准备数据来填充上面创建好的对象: 复制代码 代码如下: Private Function GetData() As List(Of Catalog) Dim cls As New List(Of Catalog) Dim cl As Catalog = New Catalog() cl.ID = 1 cl.Name = "唇膏" cls.Add(cl) cl = New Catalog() cl.ID = 2 cl.Name = "胭脂" cls.Add(cl) cl = New Catalog() cl.ID = 3 cl.Name = "化妆水" cls.Add(cl) cl = New Catalog() cl.ID = 4 cl.Name = "护手霜" cls.Add(cl) Return cls End Function 在.aspx页面拉一个Repeater控件: 复制代码 代码如下: <asp:Repeater ID="RepeaterCatalog" runat="server"> <HeaderTemplate> <table border="1" cellpadding="3" cellspacing="0"> <tr> <td>ID </td> <td>Name </td> </tr> </HeaderTemplate> <ItemTemplate> <tr> <td> <%# Eval("ID")%> </td> <td> <%# Eval("Name")%> </td> </tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> 然在.aspx.vb为Repeater控件绑定数据: 复制代码 代码如下: Imports Insus.NET Partial Class Default2 Inherits System.Web.UI.Page Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load If Not IsPostBack Then Data_Binding() End If End Sub Private Sub Data_Binding() Me.RepeaterCatalog.DataSource = GetData() Me.RepeaterCatalog.DataBind() End Sub End Class ok,一切准备绪,我们在.aspx拉一个铵钮,让用户点击此铵钮时,能对Repeater控件的数据导出Excel。 复制代码 代码如下: <asp:Button ID="Button1" runat="server" Text="Export to Excel" OnClick="Button1_Click" /> 铵钮拉好,我们要去.aspx.vb写onClick事件,在写之前,首先下载一个InsusExportToExcel Library 解压之后放入BIN目录中。 复制代码 代码如下: Protected Sub Button1_Click(sender As Object, e As EventArgs) Dim obj As New InsusExportToExcel() '实例化对象。 obj.ExportToExcel(Me.RepeaterCatalog, "catalog") '传入Repeater控件以入导出的Excel文件名。 End Sub 当然最后,少不了演示: |
