【WPF】ListView自定义分页

XAML:

  <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="*"/>
                        <RowDefinition Height="30"/>
                    </Grid.RowDefinitions>
                    <ListView Grid.Row="0" ItemsSource="{Binding Lst_bind}">
                        <ListView.View>
                            <GridView>
                                <GridView.Columns>
                                    <GridViewColumn DisplayMemberBinding="{Binding Name}" 
                                                    Width="200" Header="名字"/>

                               <!--这里用WrapPanel 当容器放Button-->
                            <ItemsControl.ItemsPanel>
                                <ItemsPanelTemplate>

                                </ItemsPanelTemplate>
                            </ItemsControl.ItemsPanel>
                        </ItemsControl>
                        <TextBlock VerticalAlignment="Center" Foreground="Black">
