Grid instances are constructed from an XML definition.

A grid can be defined inline, where the grid specifies precisely which row model, columns and decorators it has. An example of an inline grid is displayed below:

<grid displayedColumns="description, rate">
	<gridRowModel>
	   <caplin.rttp-container-grid-data-provider container="/CONTAINER/FX/G8" />
	</gridRowModel>
	  <columnDefinitions>
	   <column id="description" />
	   <column id="rate" />
	   <column id="size" />
	</columnDefinitions>
	  <decorators>
	   <dragDecorator />
	</decorators>
</grid>

Alternatively a grid can be defined using a template. This allows central configuration of the core characteristics of a particular type of grid, which can be modified without having to update every grid instance. An example of a grid defined with a template is included below:

Grid Definition

<grid displayedColumns="description, bidSize, bid, ask, askSize" />
