All Implemented Interfaces:

com.google.gwt.user.client.EventListener, IDataBinder, ISortableColumnHeaderListener, IPagerEventListener

public class DataGridWrapper
extends com.google.gwt.user.client.ui.Composite
implements IDataBinder, IPagerEventListener, ISortableColumnHeaderListener

This class is wrapper around DataGrid for custom controls. Impements IDataBinder interface for own DataGrid instance This is composite control with DataGrid and Pager. Used in CustomRBWindow It implements: - work with IAuthDataSource - anisochronous data manipulation - work with Pager - sorting data with SortableColumnHeader widget

CSS Style Rules

• .pf-dataGridWrapper { the data grid wrapper itself }

Constructor Summary

DataGridWrapper(IWindow parentWindow, IAuthDataSource dataSource, IRBColumn[] columns)
Constructor

Method Summary

void	bindHeader(IDataGridHeader dataGridHeader) Grid call this method when it wants to show cell in header In implementation of this method data binder could set text (or widget) in current header cell.
void	bindRow(IDataGridRow dataGridRow) Grid call this method when it wants to show row with data In implementation of this method data binder could set text (or widget) in all cells of current data row.
void	fireOrder(SortableColumnHeader columnHeader) Calls when user click on header text or order image
IRBColumn[]	getColumns() Gets data columns
IAuthDataSource	getDataSource() Gets data source instance
IDataGridEventListener	getEventListener() Gets events listener of DataGrid
IRowClassifier[]	getRowClassifiers() Gets row classifiers
IDataRow	getSelectedRow() Gets current selected row
void	loadData() Gets data (total count of record and data array) from IAuthDataSource by asynchronous interface and bind it into DataGrid.
void	loadData(SelectParams params) Loads data to grid from datasource with special parameters
void	pagerParamsChanged() Calls when user click on Previous or Next button and parameters like offset and limit are changed
void	setEventListener(IDataGridEventListener eventListener) Sets events listener of DataGrid
