获取Repeter的Item和ItemIndex/CommandArgument实现思路与代码
首先看看效果： Repeater控件，放在ItemTemplate内的铵钮OnClick之后，获取Repeater的Item，ItemIndex，CommandArgument，CommandName以及绑定的字段值。 准备数据： 复制代码 代码如下: 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 复制代码 代码如下: 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 = "汽车" cls.Add(cl) cl = New Catalog() cl.ID = 2 cl.Name = "时尚" 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： 复制代码 代码如下: View Code

ID	Name	Choose

在.aspx.vb为Repeater控件绑定数据： 复制代码 代码如下: 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 接下来，我们写onclick事件，在写事件之前，先在.aspx放一个Label来显示事件结果： 复制代码 代码如下: Process infor: 复制代码 代码如下: 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
