Adding Multiple Controls to the Content Area
You cannot set an accordion pane's (C1AccordionItem) Content property to more than one control at a time. However, you can circumvent this issue by adding a panel-based control that can accept more than one control, such as a StackPanel control, to the content area of the accordion pane. When you add multiple controls to the panel-based control, each one will appear within the accordion pane's content area.
This topic assumes that you have added a C1Accordion control with at least one C1AccordionItem item to your project.
To add multiple controls to the content area, complete these steps:
1. Place the following XAML markup between the <c1ext:C1AccordionItem> and </c1ext:C1AccordionItem> tags:
<c1ext:C1AccordionItem.Content>
<StackPanel>
<TextBlock Text="1st TextBlock"/>
<TextBlock Text="2nd TextBlock"/>
<TextBlock Text="3rd TextBlock"/>
</StackPanel>
</c1ext:C1AccordionItem.Content>
2. Run the program.
3. Expand the accordion pane and observe that each of the three TextBlock controls appear in the content area. The result will resemble the following:
