各位前輩:
我將UserName_2及UserName_3 , 打勾後 , 將Scorbar or 滑鼠滾動上下列 ,
那個勾勾會亂跑...
要如何修改呢??
謝謝

xaml
<Grid x:Name="LayoutRoot" Background="White"> <ListBox Grid.Row="1" Name="ListBox1" Height="250" Width="200"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox Tag="{Binding UserId}" Content="{Binding UserName}" Margin="0,10,0,0" FontSize="14" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="12,0,0,0" Name="Button1" VerticalAlignment="Top" Width="75" /> </Grid>

VB Code
Partial Public Class MainPage Inherits UserControl Public Sub New() InitializeComponent() End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click Dim UserCollection As New System.Collections.ObjectModel.ObservableCollection(Of clsUser) For i As Integer = 0 To 30 UserCollection.Add(New clsUser With {.UserId = i, _ .UserName = "UserName_" & i}) Next ListBox1.ItemsSource = UserCollection End Sub Public Class clsUser Implements System.ComponentModel.INotifyPropertyChanged Private _UserId As String Private _UserName As String Public Property UserId() As String Get Return Me._UserId End Get Set(ByVal value As String) Me._UserId = value RaiseEvent PropertyChanged(Me, New System.ComponentModel.PropertyChangedEventArgs("UserId")) End Set End Property Public Property UserName() As String Get Return Me._UserName End Get Set(ByVal value As String) Me._UserName = value RaiseEvent PropertyChanged(Me, New System.ComponentModel.PropertyChangedEventArgs("UserName")) End Set End Property Public Event PropertyChanged(ByVal sender As Object, ByVal e As System.ComponentModel.PropertyChangedEventArgs) Implements System.ComponentModel.INotifyPropertyChanged.PropertyChanged End Class End Class
