  • Repeater控件数据导出Excel

    本演示中,我们实现这个Repeater控件数据导出Excel的功能。

    我们准备一个对象:

    View Code
    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:

    View Code
        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:

    View Code
    <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:

    View Code
    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。

    <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。

    View Code
        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
