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>
      <rttpContainerGridDataProvider 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" />
