# Step 4 of 4: Running the Project

## Content



In the last step, you added accordion panes and content to the [C1Accordion](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Accordion.html) control. In this step, you will run the project and observe some of the run-time features of the [C1Accordion](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Accordion.html) control.

Complete the following steps:

1.  From the Debug menu, select **Start Debugging** to view how your application will appear at run time. Observe that the second pane, which holds the **Calendar** control, is expanded.

2.  Click **Pane 1** and observe that the first pane expands to reveal its content.

3.  Click **Pane 3** and observe that the last pane expands. Note that the third pane expands to the same width as the other panes despite the fact that it has no content.

4.  Click **Pane 3** and observe that you can't close the pane. This is because you set the [AllowCollapseAll](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Accordion.AllowCollapseAll.html) property to False, which means that one accordion pane must be expanded at all times.

Congratulations! you have completed the **Accordion for Silverlight** quick start tutorial. In this tutorial, you created a Silverlight project containing a [C1Accordion](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Accordion.html) control, modified the appearance and behavior of the control, added accordion panes and accordion pane content to the control, and then observed some of the run-time features of the control.
