We can use two constructs to access page-level variables in an ASP.NET web template:

data binding syntax

Data binding—the hierarchical mapping of control properties to data container values—is specified by the tags. Code located within a

code block is only executed when the DataBind method of its parent controlcontainer is invoked.

code rendering syntax

The code tags output content to the browser. This content could

be hard-coded, or it may contain page-level variables.
