Partial Class Default2
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.ListBox1.Items.Clear()
Dim listItems(0 To 2) As ListItem
listItems(0) = New ListItem("feifei", 0)
listItems(1) = New ListItem("sunny", 1)
listItems(2) = New ListItem("taiya", 2)
Me.ListBox1.Items.AddRange(listItems)
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
For Each li As ListItem In Me.ListBox1.Items
Response.Write(li.ToString() + ":" + li.Selected.ToString() + "<br/>")
Next
End Sub
End Class
代码是我简化出来的.为什么选定项,在显示中总是显示false.即列表框选择不了.EnableViewState属性没问题.AutoPostBack在这里属性绝对不能设为ture的.该不会是我机子的问题.帮忙看看,试试.谢谢 [em2][em1]
