Prerequisite: Complete tutorial How to use the Repeater control
Create a Type named employee with 3 fields,
FirstName, LastName and Photo
In the repeater properties, select the Listitem Type of the repeater as employee
Now you will be able to see the ListItem in SetValue (within Repeater.ItemLoad) for the different controls inside the repeater.
Why do you need to use Types?
Using Types with the repeater control gives you access to the properties of the type from within the Property Grid. Using Types will not only save you from typing the property name manually but maintenance will be easier also!
