Adding items programmatically
RadDropDownList supports adding items at run time, which means that you can manually populate it with data. The following example demonstrates how to add two different items to the RadDropDownList.Items collection.
You can use one of the following item types:
RadListDataItem – it represents a logical data item which can display specific text and image.
DescriptionTextListDataItem – similar to the RadListDataItem. In addition, it displays some description below the item’s text.
