Recyling tiles may significantly reduce the number of live tile widgets needed to support a particular TileGrid, but may also result in extra work when the TileGrid is scrolled, as a scroll that brings off-screen tiles into view will require recycling tiles that have left the view, even if the new tiles have been visited before (in previous scrolling).
Recycling will occur when getTile()
is called, unless the supplied record (or record specifed
by index) is currently bound to an existing tile. Even if recycling is not enabled, the record associated with a given
tile may change if the TileGrid data changes.

public SimpleTile getTile()
Using AutoChildren
for details.
A TileGrid automatically creates one tile per record in the dataset, via the
com.smartgwt.client.types.AutoChild
pattern.
By default, the SimpleTile
class will be used, and will contain content as
rendered
by a DetailViewer
, based on the provided fields
(or on the default
set of fields).
To create a completely different appearance set tileConstructor
to custom Canvas
class name. You can use SmartGWT classes too with help of Reflection. For example, you can
extend a DynamicForm with any layout:
public class CarTile extends DynamicForm { public CarTile() { StaticTextItem name = new StaticTextItem("name"); name.setShowTitle(false); StaticTextItem price = new StaticTextItem("price"); price.setShowTitle(false); this.setFields(pictureItem, name, price); } }Register the class factory and use it by passing it's class to tileConstructor
public interface CarTileMetaFactory extends BeanFactory.MetaFactory { BeanFactorygetCarTileFactory(); } public void onModuleLoad() { GWT.create(CarTileMetaFactory.class); TileGrid tileGrid = new TileGrid(); tileGrid.setTileConstructor(CarTile.class.getName()); tileGrid.draw(); }
public void setTileConstructor(java.lang.String tileConstructor)
com.smartgwt.client.types.AutoChild
pattern; see tile
.
Any subclass of Canvas is allowed, but typically any custom class will derive from SimpleTile
.
When using a custom component for tileConstructor, DataBoundComponents
that display multiple Records (ListGrid, DetailViewer) will have data provided via ListGrid.setData()
, and components that display a single Record
(DynamicForm) will have DynamicForm.setValues()
called on
them.
If the component is not a recognized DataBoundComponent subclass, the Record can be accessed via
this.getAttributeAsRecord("record").
If you implement particularly simple or particularly complex tile
interfaces, you may wish to adjust the property drawAllMaxTiles
.

process of mapping form fields to XML structures.
For example, having called WebService.getInputDS(java.lang.String)

schema for a web service operation whose input message looks like this:

For this form, the result of DynamicForm.getValues()
might look
like:
{ searchFor: "search text", caseSensitive: false, serviceName: true, documentation : true, keywords : true }When contacting a
WebService
, these values can be automatically
mapped to the structure of the input message for a web service operation by setting

Using these two facilities in conjunction (component.useFlatFields and request.useFlatFields) allows gratuitous nesting to be consistently bypassed in both the user presentation and when providing the data for XML messages.
You can also set useFlatFields
to automatically enable
"flattened" XML serialization (request.useFlatFields) for all DataSource requests of a
particular operationType.
Note that useFlatFields
is not generally recommended for use with structures
where multiple simple type fields exist with the same name, however if used with such a
structure, the first field to use a given name wins. "first" means the first field
encountered in a depth first search. "wins" means only the first field will be present as a
field when data binding.

useFlatFields
flag causes all simple type fields anywhere in a nested
set of DataSources to be exposed as a flat list for form binding.
useFlatFields
is typically used with imported metadata, such as
XMLTools.loadXMLSchema(java.lang.String, com.smartgwt.client.data.XSDLoadCallback)
from a
XMLTools.loadWSDL(java.lang.String, com.smartgwt.client.data.WSDLLoadCallback)
, as a means of eliminating levels of XML
nesting that aren't meaningful in a user interface, without the cumbersome and fragile
process of mapping form fields to XML structures.
For example, having called WebService.getInputDS(java.lang.String)
to retrieve the input message
schema for a web service operation whose input message looks like this:
<FindServices> <searchFor>search text</searchFor> <Options> <caseSensitive>false</caseSensitive> </Options> <IncludeInSearch> <serviceName>true</serviceName> <documentation>true</documentation> <keywords>true</keywords> </IncludeInSearch> </FindServices>Setting
useFlatFields
on a DynamicForm
that is bound to this input
message schema would result in 5 FormItem
reflecting the 5 simple type
fields in the message.
For this form, the result of DynamicForm.getValues()
might look
like:
{ searchFor: "search text", caseSensitive: false, serviceName: true, documentation : true, keywords : true }When contacting a
WebService
, these values can be automatically
mapped to the structure of the input message for a web service operation by setting
useFlatFields
(for use with WebService.callOperation(java.lang.String, java.util.Map, java.lang.String, com.smartgwt.client.data.WebServiceCallback)
) or by setting
useFlatFields
(for use with a DataSource
that is
'bound to a WSDL web service'
via
wsOperation
).
Using these two facilities in conjunction (component.useFlatFields and request.useFlatFields) allows gratuitous nesting to be consistently bypassed in both the user presentation and when providing the data for XML messages.
You can also set useFlatFields

DataBoundComponent
When fetchData()
is first called, if data has not already been provided via
setData()
, this method will create a ResultSet
, which will be
configured based on component settings such as fetchOperation
and dataPageSize
, as well
as the general purpose dataProperties
. The created ResultSet will automatically send a DSRequest
to retrieve data from the dataSource, and from then on will
automatically manage paging through large datasets, as well as performing filtering and
sorting operations inside the browser when possible - see the ResultSet docs for
details.
NOTE: do not use both autoFetchData
and a
call to fetchData()
- this may result in two DSRequests to fetch data. Use
either autoFetchData
and setAutoFetchCriteria()
or a manual call to fetchData()
passing criteria.
Whether a ResultSet was automatically created or provided via setData()
, subsequent
calls to fetchData() will simply call resultSet.setCriteria()
.
Changes to criteria may or may not result in a DSRequest to the server due to
client-side filtering. You can call
willFetchData(criteria)
to determine if new criteria will
result in a server fetch.
If you need to force data to be re-fetched, you can call
invalidateCache()
and new data will
automatically be fetched from the server using the current criteria and sort direction. NOTE:
when using invalidateCache()
there is no need to also call fetchData()
and in fact this could produce unexpected results.
This method takes an optional callback parameter (set to a DSCallback
)
to fire when the fetch completes. Note that this callback will not fire if no server fetch is performed.
In this case the data is updated synchronously, so as soon as this method completes you
can interact with the new data. If necessary, you can use
resultSet.willFetchData()
to determine whether or not a server
fetch will occur when fetchData()
is called with new criteria.
In addition to the callback parameter for this method, developers can use

to be notified every time data is loaded.

manually call fetchData() after invalidateCache() and this could result in duplicate
fetches.
While data is being re-loaded after a call to invalidateCache()
, the widget
is in a state similar to initial data load - it doesn't know the total length of the
dataset and any APIs that act on records or row indices will necessarily fail and should
not be called. To detect that the widget is in this state, call
ResultSet.lengthIsKnown()
.
invalidateCache()
only has an effect if this component's dataset is a data
manager class that manages a cache (eg ResultSet or ResultTree). If data was provided as
a simple Array or List, invalidateCache() does nothing.

Depending on the component configuration, the actual JavaScript instance of the returned RecordList may be one of several types:
DataSource

the instance is generally an Array of Record
.ResultSet
.Tree
.
To access the ungrouped record list regardless of grouping status, use
isGrouped() ? getOriginalRecordList() : getRecordList()

Java wrappers of the field class type (e.g.

This is an advanced method and only for cases where you have the JavaScriptObject for
each field but want to avoid having to create each associated SmartGWT Java wrapper.
Note: use toArray()
to create a Java
array of JavaScriptObject if you only have the array itself as a single JavaScriptObject.
