The sample demonstrates igTreeGrid contextRowMode option with two of the three possible modes.
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
Paging with contextRowMode: parent
Paging with contextRowMode: breadcrumb
The three possible modes for igTreeGrid contextRowMode option are "none," "parent," and "breadcrumb." These modes allow rendering of a context row below the grid headers that contains information about the parent(s) of the first row in the page. The top grid shows contextRowMode option set to "parent," which will render a representation of the immediate parent row. The bottom grid shows contextRowMode option set to "breadcrumb," which will render a breadcrumb trail representing the full path through all ancestors of the first row. By default the option is set to "none," in which case no context row is rendered.
