为什么listbox 加载这么慢？
<ListBox x:Name="MainListBox">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="1">
<TextBlock Width="50" FontSize="20" TextWrapping="Wrap" VerticalAlignment="Top" HorizontalAlignment="Left" Text="{Binding Path=Id}" />
<TextBlock Width="150" FontSize="26" TextWrapping="Wrap" VerticalAlignment="Top" HorizontalAlignment="Left" Text="{Binding Path=username}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
protected override void OnNavigatedTo(NavigationEventArgs e)
{
int fromrow = pageid * pagesize;
string strSelect = "SELECT * FROM user limit 10";
ObservableCollection<userModel> userEntries = (Application.Current as App).db.SelectObservableCollection<userModel>(strSelect);
this.MainListBox.DataContext = userEntries;
}
