The Grid component is intended to be used as a DataGrid skin part, or as an element of other custom composite components. Therefore, it is not skinnable, it does not include a scroller or scrollbars, and it does not provide default mouse or keyboard event handling.
Each visible Grid cell is displayed by a GridItemRenderer
instance created by using the itemRenderer property.
specify an item renderer for each column.
Before it is displayed, each item renderer instance is configured
with the value of the data provider item for that row.
Item renderers are created as needed and then, to keep creation
overhead to a minimum, pooled and recycled.
The Grid control supports selection, according the selectionMode
property. The set of selected row or cell indices can be modified or
queried programatically using the selection methods, such as
setSelectedIndex or selectionContainsIndex().
The Grid control displays hover, caret, and selection indicators based
on the selectionMode property and the corresponding
row index and column index properties, such as
hoverRowIndex and columnRowIndex.
An indicator can be any visual element.
Indicators that implement IGridVisualElement can configure themselves
according to the row and column in which they are used.
The Grid control supports smooth scrolling. Their vertical and horizontal scroll positions define the pixel origin of the visible part of the grid and the grid's layout only displays as many cell item renderers as are needed to fill the available space.
The Grid control supports variable height rows that automatically compute
their height based on the item renderers' contents.
This support is called grid virtualization
because the mapping from (pixel) scroll positions to row and column indices
is typically based on incomplete information about the preferred sizes
for grid cells.
The Grid caches the computed heights of rows that have been
scrolled into view and estimates the rest based on a single
typicalItem.
Transitions in DataGrid item renderers aren't supported. The GridItemRenderer class
has disabled its transitions property so setting it will have no effect.

label on each data provider item and displays it.
However, if the data provider does not contain a label
property, you can set the dataTipField property to

Specifies a callback function to run on each item of the data provider
to determine its data tip.
This property is used by the itemToDataTip method.
By default, if showDataTips is true,
the column looks for a property named label
on each data provider item and displays it as its data tip.
However, some data providers do not have a label property
nor do they have another property that you can use for displaying data
in the rows.
For example, you have a data provider that contains a lastName
and firstName fields, but you want to display full names as the data tip.
You can specify a function to the dataTipFunction property
that returns a single String containing the value of both fields. You
can also use the dataTipFunction property for handling
formatting and localization.
The signature of the dataTipFunction function must match the following:
dataTipFunction(item:Object, column:GridColumn):StringThe
item parameter is the data provider item for an entire row.
The second parameter is this column object.
A typical function might concatenate an item's firstName and lastName properties, or do some custom formatting on a Date value property.

If the specified cell is visible, it is redisplayed.
If variableRowHeight=true,
then doing so may cause the height of the corresponding row to change.
If columnIndex is -1, then the entire row is invalidated.
Similarly if rowIndex is -1, then the entire column is invalidated.
This method should be called when there is a change to any aspect of
the data provider item at rowIndex that might have some
impact on the way the specified cell is displayed.
Calling this method is similar to calling the
dataProvider.itemUpdated() method, which advises the Grid that all rows
displaying the specified item should be redisplayed.
Using this method can be relatively efficient, since it narrows
the scope of the change to a single cell.
