OBJECTIVE:
As I know the <GroupHeaderTemplate> is not directly associated with the data therefore I cannot establish a context for DTOs. I wish you access the data collection and display data dynamically using the <GroupHeaderTemplate>. In this case I want to showcase days of the week along side the date based on the data in my DTOs rather than the default that is given from DateTime.
QUESTION:
How would I go about displaying dynamic data in a <GroupHeaderTemplate> the same way it is done in other Telerik Templates?
Below is the relevant code the produces my question.
