本演示中，我們實現這個Repeater控件數據導出Excel的功能。
我們准備一個對象：
復制代碼 代碼如下:
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
准備數據來填充上面創建好的對象：
復制代碼 代碼如下:
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 = "化妝水" cls.Add(cl) cl = New Catalog() cl.ID = 4 cl.Name = "護手霜" cls.Add(cl) Return cls End Function
在.aspx頁面拉一個Repeater控件：
復制代碼 代碼如下:
<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為Repeater控件綁定數據：
復制代碼 代碼如下:
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，一切准備緒，我們在.aspx拉一個铵鈕，讓用戶點擊此铵鈕時，能對Repeater控件的數據導出Excel。
復制代碼 代碼如下:
<asp:Button ID="Button1" runat="server" Text="Export to Excel" OnClick="Button1_Click" />
铵鈕拉好，我們要去.aspx.vb寫onClick事件，在寫之前，首先下載一個InsusExportToExcel Library 解壓之後放入BIN目錄中。
復制代碼 代碼如下:
Protected Sub Button1_Click(sender As Object, e As EventArgs)
Dim obj As New InsusExportToExcel() '實例化對象。
obj.ExportToExcel(Me.RepeaterCatalog, "catalog") '傳入Repeater控件以入導出的Excel文件名。
End Sub
當然最後，少不了演示：
