# Page Fold Visibility

## Content



By default, users will see a page fold when their mouse is over certain book zones. If you choose to, however, you can change the page fold visibility. You can set the [C1Book.ShowPageFold](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Book.ShowPageFold.html) property to any of the values in the following table to determine how users interact with the [C1Book](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Book.html) control:

|   **Value**   |   **Description**   |
| --- | --- |
|   OnMouseOver   |   The fold will be visible when the user drags the mouse over the edge of the page. This is the default setting.   |
|   Never   |   The fold will not be visible.   |
|   Always   |   The fold will always be visible.   |
