Repeater控件数据导出Excel(附演示动画)

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：
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： 
 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： 
 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： 
 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。 
 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。 
 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：
