# Book Template Parts

## Content



In Microsoft Expression Blend, you can view and edit template parts by creating a new template (for example, click the [C1Book](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Book.html) control to select it and choose **Object** **| Edit Template** **| Edit a Copy**). Once you've created a new template, the parts of the template will appear in the **Parts** window:

Note that you may have to select the **ControlTemplate** for its parts to be visible in the **Parts** window.

In the Parts window, you can double-click any element to create that part in the template. Once you have done so, the part will appear in the template and the element's icon in the **Parts** pane will change to indicate selection.

Template parts available in the **C1Book** control include:
