首先看看效果：
Repeater控件，放在ItemTemplate內(nèi)的銨鈕OnClick之后，獲取Repeater的Item，ItemIndex，CommandArgument，CommandName以及綁定的字段值。
準備數(shù)據(jù)：
復(fù)制代碼 代碼如下:
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
復(fù)制代碼 代碼如下:
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 = "汽車"
cls.Add(cl)
cl = New Catalog()
cl.ID = 2
cl.Name = "時尚"
cls.Add(cl)
cl = New Catalog()
cl.ID = 3
cl.Name = "科技"
cls.Add(cl)
cl = New Catalog()
cl.ID = 5
cl.Name = "文化"
cls.Add(cl)
cl = New Catalog()
cl.ID = 6
cl.Name = "公益"
cls.Add(cl)
Return cls
End Function
在.aspx放置Repeater控件：
復(fù)制代碼 代碼如下:
View Code
asp:Repeater ID="RepeaterCatalog" runat="server">
HeaderTemplate>
table border="1" cellpadding="3" cellspacing="0">
tr>
td>ID
/td>
td>Name
/td>
td>Choose/td>
/tr>
/HeaderTemplate>
ItemTemplate>
tr>
td>
asp:Label ID="LabelID" runat="server" Text='%# Eval("ID")%>'>/asp:Label>
/td>
td>
asp:Label ID="LabelName" runat="server" Text='%# Eval("Name")%>'>/asp:Label>
/td>
td>
asp:Button ID="Button1" runat="server" Text="Select" OnClick="Button1_Click" CommandArgument='%# Eval("ID")%>' CommandName="Choose" />
/td>
/tr>
/ItemTemplate>
FooterTemplate>
/table>
/FooterTemplate>
/asp:Repeater>
在.aspx.vb為Repeater控件綁定數(shù)據(jù)：
復(fù)制代碼 代碼如下:
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
接下來，我們寫onclick事件，在寫事件之前，先在.aspx放一個Label來顯示事件結(jié)果：
復(fù)制代碼 代碼如下:
Process infor:
asp:Label ID="LabelInfo" runat="server" Text="">/asp:Label>
復(fù)制代碼 代碼如下:
View Code
Protected Sub Button1_Click(sender As Object, e As EventArgs)
Dim btn As Button = DirectCast(sender, Button)
Dim commandArgument As String = btn.CommandArgument
Dim commandName As String = btn.CommandName
Dim item As RepeaterItem = DirectCast(btn.NamingContainer, RepeaterItem)
Dim index As Integer = item.ItemIndex
Dim id As String = DirectCast(item.FindControl("LabelID"), Label).Text
Dim name As String = DirectCast(item.FindControl("LabelName"), Label).Text
Me.LabelInfo.Text = String.Format("Item index: {0}; CommandArgument: {1}; CommandName: {2}; ID: {3}; Name: {4};", index, commandArgument, commandName, id, name)
End Sub
