嗨    iDontKnowEverything， 



>>如果有成千上万的radiobuttons，我怎么能快速做到这一点



据我所知，当你有成千上万的面板中的radiobuttons。主要问题是UI的延迟和缓慢，影响操作和体验。



因此，我建议您可以尝试在WPF中使用UI虚拟化，其次是数据虚拟化。 UI虚拟化最大限度地减少了绘制的内容，数据虚拟化最大限度地减少了可以绘制的内容。



一个简单的示例：

Hi   iDontKnowEverything, 

>> If there are Thousands of radiobuttons, how can I do this quickly

As I understand, when you have Thousands of radiobuttons in the panel. The main problem is the delay and slowness of the UI, affecting operations and experience.

So, I suggest you can try to use the UI Virtualization in WPF and second is Data Virtualization. The UI virtualization minimizes the number of things drawn and data virtualization minimizes the number of things that could be drawn.

A simple Sample:

 <StackPanel>
            <ScrollViewer CanContentScroll="True">
                <VirtualizingStackPanel x:Name="visualsp"  VirtualizationMode="Recycling" Width="800" Height="300">
                </VirtualizingStackPanel>
            </ScrollViewer>
            <Button x:Name="LoadDataButton" Content="Load Data"   VerticalAlignment="Top" 
Click="LoadDataButton_Click"/>
        </StackPanel>

 private void LoadDataButton_Click(object sender, RoutedEventArgs e)
        {
            for (var count = 1; count < 10001; ++count)
            {
                RadioButton rb = new RadioButton();
                rb.Content = "count" + count.ToString();
                rb.IsChecked = false;
                visualsp.Children.Add(rb);
            }
        }
