# Adding Multiple Controls to the Content Panel
## Content
You cannot set the **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 panel of [C1HeaderedContentControl](/componentone/api/wpf/online-basiclibrary/dotnet-framework-api/C1.WPF.4.6.2/C1.WPF.C1HeaderedContentControl.html). When you add multiple controls to the panel-based control, each one will appear within the **C1HeaderedContentControl**'s content panel.
**In XAML**
To add a button control to the **C1HeaderedContentControl**'s content panel in XAML, complete the following steps:
1. Place the following XAML markup between the `` and `` tags:
```xml
```
2. Run the program.
3. Expand **C1HeaderedContentControl** and observe that each of the three **TextBlock** controls appear in the content panel.
**In Code**
To add multiple controls to the content panel, complete these steps:
1. Enter Code view and add the following code beneath the **InitializeComponent()** method:
