## Properties

* **RadRibbonView Selection Properties**
  * **SelectedItem**: A property of type object that gets or sets the currently selected ribbon tab item.

    > If the **RadRibbonView** control is bound to a custom collection, then the property **SelectedItem** will not return **RadRibbonTab** as you might expect, but item of the type the source collection contains.

  * **SelectedIndex**: A property of type int that gets or sets the index of the currently selected ribbon tab item.
* **RadRibbonTab Selection Properties**

  * **IsSelected**: A boolean property that specify if given tab is selected. If you want to make a tab selected, just set this property to **True** otherwise set it to **False**.

## Events

  * **AddedItems**: An **IList** collection of the selected items.
  * **RemovedItems**: An **IList** collection of the unselected items.

  > tip You can cancel the selection by setting the **RadSelectionChangedEventArgs**'s **Handled** property to **True**.

* **SelectionChanged**: Event raised after the tab selection is done. The event arguments are of type **RadSelectionChangedEventArgs** and expose the following members:
  * **AddedItems**: An **IList** collection of the selected items.

This code snippet shows you how to attach to the selection events:

#### **Example 1: Subscribe to Preview/SelectionChanged event**

```XAML
<telerik:RadRibbonView x:Name="radRibbonView" PreviewSelectionChanged="radRibbonView_PreviewSelectionChanged" SelectionChanged="radRibbonView_SelectionChanged">
...
</telerik:RadRibbonView>
```

Below is a sample implementation of both of the event handlers:

#### **Example 2: Event Handlers**

```C#
private void radRibbonView_PreviewSelectionChanged(object sender, RadSelectionChangedEventArgs e)
{
	// Custom code
	// Cancel the selection
	e.Handled = true;
}
private void radRibbonView_SelectionChanged(object sender, RadSelectionChangedEventArgs e)
{
	//Get the selected items
	IList selectedItems = e.AddedItems;
	//Get the unselected items
	IList unselectedItems = e.RemovedItems;
}
```
