Hi,
I have a carousel, and when i scroll , click through the items and then double click on a item, I would like to extract the  value from the carousel. As I can't see anything obvious like you would find in a combo box.

For example I have  a list of employees with a 'name' and 'employee id'. I select double click on a employee and i want to then be able to get the employee id.

My Xaml

Hi Simon Allport,

You could either use SelectedItem or CurrentItem in chi situation. Just cast SelectedItem or CurrentItem to your data type and you will be able to get access to the properties:

01.private void Image_MouseDown(object sender, MouseButtonEventArgs e)  
02.        {  
03.            if (e.ClickCount >= 2)  
04.            {  
05.              // Get the selected value here!!    
06.                var selectedItem = (MyDataType)radCarousel1.CurrentItem;  
07.                var name = selectedItem.Name;
08.                   
09.                string x = e.OriginalSource.ToString();  
10.            }  
11.        }

Hope this helps.
