动态添加子扩展器

Question

有没有办法在运行时创建像这样的xaml轰鸣声的子扩展器？

<Expander Header="Building" IsExpanded="True">
    <StackPanel>
        <Expander Header="Sales">
            <StackPanel>
                <TextBlock>6100</TextBlock>
                <TextBlock>6101</TextBlock>
                <TextBlock>6111</TextBlock>
                <TextBlock>6150</TextBlock>
            </StackPanel>
        </Expander>
        <Expander Header="Director">
            <StackPanel>
                <TextBlock>6102</TextBlock>
                <TextBlock>6113</TextBlock>
            </StackPanel>
        </Expander>
    </StackPanel>
</Expander>

Answer 1

在顶部Expander下设置第一个StackPanel(MainStackPanel)的名称.

// Add new expander, stack panel and text block.
var newExpander = new Expander {Name = "NewExpander", Header = "New Expander"};
var newstackPanel = new StackPanel {Name = "NewExpanderStackPanel"};
var newtextBlock = new TextBlock {Text = "777"};

// Add above items as children.     
newstackPanel.Children.Add(newtextBlock);
newExpander.Content = newstackPanel;
MainStackPanel.Children.Add(newExpander);
