The Spark DataGrid control is implemented as a skinnable wrapper around the Spark Grid control. The Grid control defines the columns of the data grid, and much of the functionality of the DataGrid control itself.
The DataGrid skin is responsible for laying out the grid, column header, and scroller. The skin also configures the graphic elements used to render visual elements used as indicators, separators, and backgrounds. The DataGrid skin also defines a default item renderer, used to display the contents of each cell. Please see the documentation for the renderer class for the list of supported styles.
Transitions in DataGrid item renderers aren't supported. The GridItemRenderer class
has disabled its transitions property so setting it will have no effect.

dataTipFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10, AIR 2.5 |
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.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the dataTipFunctionChanged event.

If the event is not canceled, it then commits the selection change, and then
dispatches the selectionChange event.
The caret location is not updated.
To detect if the caret has changed, use the caretChanged event.
Parameters
selectionEventKind:String — A constant defined by the GridSelectionEventKind class
that specifies the selection that is being committed. If not null, this is used to
generate the selectionChanging event.
| |
rowIndex:int — If selectionEventKind is for a row or a

If necessary, set the verticalScrollPosition and
horizontalScrollPosition properties so that the
specified cell is completely visible.
If rowIndex is -1 and columnIndex is specified,
then just adjust the horizontalScrollPosition
so that the specified column is visible.
If columnIndex is -1 and rowIndex
is specified, then just adjust the verticalScrollPosition
so that the specified row is visible.
Parameters
rowIndex:int — The 0-based row index of the item renderer's cell, or -1 to specify a column.

invalidateCell | () | method |
public function invalidateCell(rowIndex:int, columnIndex:int):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4.5 |
| Runtime Versions: | Flash Player 10, AIR 2.5 |
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.
Parameters
rowIndex:int — The 0-based row index of the cell that changed, or -1.
| |
columnIndex:int — The 0-based column index of the cell that changed or -1.

Dispatched before the sort has been applied to the data provider's collection. Typically this is when the user releases the mouse button on a column header to request the control to sort the grid contents based on the contents of the column. Only dispatched if the column is sortable and the data provider supports sorting.
The DataGrid control has a default handler for this event that implements
a single-column sort and updates the visibleSortIndices in the grid's
columnHeaderGroup with the columnIndices.
Multiple-column sort can be implemented by calling the preventDefault() method
to prevent the single column sort and setting the columnIndices and
newSortFields parameters of the event to change the default behavior.
newSortFields should be set to the desired sort fields.
columnIndices should be set to the indices of the columns that should
have a visible sort indicator in the column header bar.
This event is dispatched when the user interacts with the control.
When you sort the data provider's collection programmatically,
the component does not dispatch the sortChanging event.
GridSortEvent.SORT_CHANGING constant defines
the value of the type property of the event object for a
sortChanging event, which indicates that a sort filter is about to be

A very simple DataGrid example.
The ArrayCollection is the list of dataProvider items, one per DataGrid row and the DataGrid
automatically creates one column for each property in the first item. The dataProvider
property tag isn't specified because it's the default property and leaving it out makes the code
just a little simpler looking. Although any class that implements IList can be used an a
dataProvder, ArrayCollection is convenient because it enables the column sorting support.
We've used the s:DataItem class to create data items for this example although in this case
fx:Object would have worked equally well, because the example doesn't rely on data item
property bindings. DataItem is used to define an untyped Object whose properties are bindable.

A simple combination of Spark DataGrid and Form that demonstrates using the DataGrid
selectedItem property to connect "master" and "detail" views.
The value of the DataGrid's selectedItem property is the dataProvider item that's
currently selected. This example displays a Datagrid and a Form, and the Form
displays various aspects of the selectedItem. Elements of the Form bind to the
DataGrid's selectedItem, so when the selection changes the form is updated
automatically. In a configuration like this, the DataGrid is the "master" view
and the Form is the "detail" view.
The selectedItem bindings are not valid unless there's a non-null selection, so
we've specified requireSelection="true" for the DataGrid. Note also that we've
used a CurrencyFormatter to convert Numbers that represent prices, to nicely formatted
and localized strings.

Demonstrate using the DataGrid typicalItem property to initialize column widths
and the invalidateTypicalItem() method to notify the DataGrid about typicalItem
property changes.
Use the input fields at the top of the application to change typicalItem properties.
Use tab to commit the typicalItem change.
The DataGrid's typicalItem is used to compute the initial width of each GridColumn that
doesn't specify an explicit width. When the DataGrid's width is unconstrained, then its
overall width is essentially the sum of the column widths. If the DataGrid's width is
constrained, for example if left and right are specified, then the typicalItem column widths
may be padded so that all of the available horizontal space is allocated.
The typicalItem is used the first time the DataGrid is measured and if a typicalItem wasn't
specified, then the first dataProvider item is used. To compute column widths, a renderer is created
and validated, its preferred size is recorded, and then the renderer is discarded.
The advantage of basing column widths on the typicalItem, instead of specifying explicit GridColumn
widths, is that doing so incoporates hard to predict factors like font sizes and styles, or
localized text values.
Because typical item column widths are cached, it's necessary to notify the DataGrid when the
typicalItem has changed. This is done by calling the DataGrid invalidateTpyicalItem() method.
In this example each input field calls invalidateTypicalItem() when a typicalItem property is changed.

Demonstrate the DataGrid variableRowHeight and rowHeight properties.
When variableRowHeight="false" (the default) use the slider to change the row height
of all the DataGrid's rows. When variableRowHeight="true", each row's height is computed.
With the variableRowHeight checkbox checked, try adding enough text to a string in the
"name" column to cause the renderer to wrap, or resize the column's width by dragging
the header's column separators.
By default all of the rows in a DataGrid have the same height. The rows' heights are
defined by the rowHeight property and if its value is not specified, the computed "preferred"
height of the first row is used. If the variableRowHeight property is set to true,
then the height of each row is the maximum measured height of each cell that's been exposed,
so far. That means that when the DataGrid's columns aren't all visible and variableRowHeight="true",
scrolling new columns into view can cause a row's height to grow. Similarly, the DataGrid
uses the first row's height (or the rendered height of the "typicalItem", if it was specified)
as an estimate for the heights of rows that haven't been scrolled into view yet. This means
that the DataGrid Grid's contentHeight, i.e. total height of all of the rows, can grow or even
shrink as it's scrolled, when variableRowHeight=true. Since the scrollbar's thumb size reflects
the content size, you may see its height change a little as you scroll, although as the number
of rows gets large, this effect usually isn't noticeable.
The runtime support for variable height rows requires quite a bit more bookkeeping than the
variableRowHeight="false" case and there's a commensurate impact on performance and footprint.
That's why by default the DataGrid is configured for fixed height rows. That said, item
renderer complexity tends have a much bigger impact on display/scrolling performance, so
developers need not shy away from specifying variableRowHeight=true, even when optimizing for
performance.

A DataGrid example that demonstrates the selectionChange and selectionChanging events,
the "multipleCells" selection mode, a dataProvider that's a two dimensional array of
numbers, and a column whose values are computed and can not be selected.
This application displays the min, max, and average value of the selected cells. The DataGrid's
last column displays the computed min and max values for each row.
DataGrid supports five selection modes including GridSelectionMode.MULTIPLE_CELLS ("multipleCells").
Specifying selectionMode="multipleCells" enables selection of individual cells with mouse click or
control-click or rectangular groups of cells with shift-click. Each time the user attempts to
change the selection the DataGrid dispatches a "selectionChanging" event and, if that event is
not cancelled with event.preventDefault(), a "selectionChange" and a "valueCommit" event.
This application uses the changing event to cancel attempts to include the last column in the
selection, because the last column isn't part of the dataProvider, it's just a summary of the
row's values in term of the minumum and maximum.
To handle the special case where the user attempts to select all cells by typing
control-A, we cancel the selectionChanging event and then use dataGrid.selectCellRegion()
to select all cells except those in the last column. The valueCommit event is dispatched
when the selection changes for any reason, not just in response to user input, and so we
use that to update the selectionMinimum,Maximum,Average variables.
Each time the selection changes, the application's selectionChangeHandler() method updates
the three bindable variables that are dispayed in the control bar. The DataGrid's
selectedCells property contains the row,column indices of the selected cells as a
Vector of CellPosition objects.

This example demonstrates the use of the DataGrid invalidateCell() method.
Pressing the "Run" button starts a timer that updates DataGrid cells at the
rate specified with the slider.
This "Christmas Tree" DataGrid example displays a dataProvider with items whose
substructure is constantly changing. Each dataProvider item has one object
valued property per column, and each of those properties has an object value
that defines what's displayed in a single cell. To keep things simple the
column properties are just called "C0", "C1", ... and the value of each property
is an object itself, with "color" and "index" properties, like {color:NN, index:NN}.
So the data for the cell at rowIndex=10, columnIndex=5:
dataGrid.dataProvider.getItemAt(10)["C5"] => {color:0xFF6C0D, index:4}
The DataGrid has no way of knowing when the color,index data for a cell has been updated
so the developer must call invalidateCell(rowIndex, columnIndex) to let the DataGrid
know that the specified cell must be redisplayed. When the "Run" button is toggled
on, updateTimerHandler() method below is called up to 64 times/second and each
time it updates a single random cell's color and index properties and then calls
invalidateCell(). Calling invalidateCell() only causes the (one) corresponding item
renderer to redisplay, so long as doing so doesn't invalidate the corresponding row's
height. That can occur if variableRowHeight=true and if it does, the entire DataGrid
is redisplayed.
The CPU load produced by applications like this one is only proportional to the update rate
and the renderers' complexity, so long as the overall grid layout isn't affected by
the cell updates. Using fixed height rows with variableRowHeight="false" (the default),
simple item renderers, and not dynamically changing column widths, are good ways to ensure
that the CPU load is minimized.
