# Click Mode

The **RadExpander** control exposes a **ClickMode** property to allow you to determine when the content of the control should be expanded. The property is an enumeration of type **ClickMode** that exposes the following members:

* **Release**: Specifies that the content should be expanded when the left mouse button is pressed and released on top of the **Header** of the control. If you are using the keyboard, this setting specifies that the content should be expanded when the header is focused and the **Space** or **Enter** key is pressed and released.

* **Press**: Specifies that the content should be expanded when the left mouse button is pressed on top of the **Header** of the control. If you are using the keyboard, this setting specifies that the content should be expanded when the header is focused and the **Space** or **Enter** key is pressed.

* **Hover**: Specifies that the content should be expanded when the mouse pointer hovers over the header.

> The default value of the **ClickMode** property is **Release** which means that by  default the **RadExpander** control is expanded when the left mouse button is released after a click on the header or when  the **Enter** or **Space** keys are released while focusing the header.
