Here is my code ,

```
string _towns = String.Join(",", 
(usercontrol.FindControl("comboTown") as RadComboBox).CheckedItems);

```

'comboTown' has the values 

```
Town1
Town2
Town3
Town4

```

If I checked `Town2` and `Town3` , I want to get the single string likes `Town2,Town3` separated by comma . But my code return `Telerik.Web.UI.RadComboBoxItem,Telerik.Web.UI.RadComboBoxItem` . How can I get only the value of checked items ?
