# Initial Expand State

## Content



By default, the [C1Expander.IsExpanded](/componentone/api/wpf/online-extended/dotnet-framework-api/C1.WPF.Extended.4.6.2/C1.WPF.Extended.C1Expander.IsExpanded.html) property is set to **False**, which means that the control appears in its collapsed state when the page is loaded. If you want the control to be expanded upon page load, you can set the **IsExpanded** property to **True** .

The following table illustrates the difference between the two expand states.

|   **IsExpanded**   |   **Result**   |
| --- | --- |

|   **IsExpanded=True**   |   **![](https://cdn.mescius.io/document-site-files/images/babf1807-69aa-4d8a-96b6-d6c6d9325368/silverlightdocuments/documents/graphics/c1expander/narrative/isexpanded_true.png)**   |

You can set the expand states in Blend, XAML, or code.
