Are you tired of using view panels to display data in XPages? This webinar will show how you can provide a new look and feel and rich functionality with several variations of Dojo data grids. You'll learn about the XPages Dojo Data Grid control and its key features, including infinite scrolling, sorting, and editable cells. Then you'll see how to transform the grid into a Dojo EnhancedGrid and take advantage of enhanced plugins to provide even more functionality, such as multi-rule filtering and context menus. Finally, you'll get a glimpse of how to bypass the grid control in order to create a categorized Dojo TreeGrid. You'll come away with a myriad of options for providing appealing, interactive, highly functional data grids.

15. Agenda
• Dojo Data Grid Control
• Creation and Default Features
• Dojo Data Grid – Additional Features
• Sorting, Opening Docs, Searching, Editing
• Dojo EnhancedGrid
• Conversion
• Plugins
• Dojo TreeGrid
• Categorization
• Counts and Totals
3

16. Dojo Data Grid Control
• Availability
• Extension Library
• 8.5.3 Upgrade Pack 1
• Notes 9
• Creates a Dojo DataGrid
4

17. Why Use the Dojo Data Grid?
• It’s not a view panel
• Feature-rich
• Adjustable columns, sorting, editing…
• Dojo is already on the Domino server
• Enhanced plugins available
5

18. Creating a Dojo Data Grid
1. Create REST Service to provide data
2. Add the Dojo Data Grid control and bind to the
REST service
3. Add Dojo Data Grid Columns
6

19. REST Service
• REST is a standard for client-server data exchange
on the web
• Common method for providing data to a grid
• REST Service Control (ExtLib, 8.5.3 UP1, R9)
• Data Access > REST Service
7

20. REST Service - Creation
1. Add REST Service control to the page
2. Select the service type
• basics > service > + > xe:viewJsonService
3. Set the contentType to application/json
• basics > service > contentType
4. Select the view
• basics > service > viewName
5. Set defaultColumns to true
• basics > service > defaultColumns 8

21. REST Service - Customization
• Compute columns
• System columns
• Roll your own
9

22. REST Service – Verification
• Set pathInfo
• All Properties > basics > pathInfo
• Test it
• Server.com/dbname.nsf/XPage.xsp/pathInfoName
10

23. Creating a Dojo Data Grid
1. Create REST Service to provide data
2. Add the Dojo Data Grid control and bind to the
REST service
3. Add Dojo Data Grid Columns
11

24. Default Grid Features
• Infinite scrolling
• Adjustable column widths
• Row highlighting
• Extended selection mode
• Sortable columns
• Multiple row entries
12

25. Additional Grid Properties
• rowSelector
• autoHeight
• rowsPerPage
• escapeHTMLInData
• loadingMessage
• errorMessage
• dir
13

26. Dojo Attributes
• More grid features are available, but not via
properties
• e.g. Column Reordering, Grid Width
• Dojo > Dojo attributes:
or
• All Properties > dojo > dojo attributes
14

27. Column Reordering
• Allows user to rearrange columns
• Set via dojo attribute
15

28. Column Reordering
• Alternate Method of Setting Attribute
16

29. Grid Width
• By default, takes up width of container
• autoWidth attribute sizes to required width
• Set via dojo attribute
17

30. Grid Column Properties
• label
• width
• hidden
• editable
• formatter
• Example: format to all upper case
function allUpper(value) {
return value.toUpperCase();
}
18

31. Sorting
• Automatically attempts to provide ascending and
descending sorting on all columns
• Each sort only works if enabled in underlying view
19

32. Preventing Sort Options
• Attach a function to the canSort property of grid
• Receives column index number
• 1-based index
• Ascending sort is positive number, descending is negative
• Returns true or false
• Run code onClientLoad of page to attach function
• Example: Allow even numbered columns to sort
dijit.byId('#{id:djxDataGrid1}').canSort = function(col){
if (col % 2 == 0) {
return true;
} else {
return false;
}
};
20

33. Opening Documents
• Link not built-in
• Row click events: onRowClick, onRowDblClick
• Client JavaScript
• Events receive an argument with many properties
• Code varies based on REST service type
21

34. REST Service Output
viewJsonService viewItemFileService
22

35. Open Doc - viewJsonService
var grid = arguments[0].grid;
var index = arguments[0].rowIndex;
var item = grid.getItem(index);
var unid = item[‘@unid’];
var url = ‘MyPageName.xsp?documentId=‘ + unid +
‘&action=openDocument’;
window.document.location.href = url;
23

36. Open Doc - viewItemFileService
var index = arguments[0].rowIndex;
var unid = REST_SERVICE_NAME._items[index].attributes[‘@unid’];
var url = ‘MyPageName.xsp?documentId=’ + unid +
‘&action=openDocument’;
window.document.location.href = url;
24

37. Search – Full Text
• Same steps as other display controls
• Steps:
1. Create search field and bind to scope var
2. Set REST service’s search property to scope var
3. Add button that triggers partial refresh on grid and
REST service
• Cannot sort results
• DB must be full-text indexed
25

38. Editable Columns
• Set column’s editable property to true
• Double-click cell to change to edit mode
• Save the changes – one line of client JavaScript
• REST_SERVICE_ID.save()
• Use the jsId property if defined (else, id)
• **Does not work without grid autoHeight set
• Undo changes – one line of JavaScript (in theory)
• REST_SERVICE_ID.revert()
• Partial refresh on grid has same effect
26

39. Editable Columns – Field Types
• cellType property
• Cell (default) – plain text
• Select – drop-down list (compute options w/ SSJS)
• Bool – checkbox
• AlwaysEdit – not a field type
• RowIndex – nothing to do with editing!
27

40. Editable Columns – Field Types
• Edit date field with date picker
• 1 – Include module: dojox.grid.cells.DateTextBox
• 2 – Set cell type: dojox.grid.cells.DateTextBox
• Only works in Notes 9
28

41. Editable Columns
• REST service’s save() function can accept callbacks
• Useful for displaying an error if save fails
var saveCallbacks = {onError: function()
{alert('There was an error saving your changes.');}};
restServiceID.save(saveCallbacks);
• Editable columns work with viewItemFileService,
but require a Web Site document to work with
viewJsonService
• Can only edit columns mapped to a single field
• Grid has singleClickEdit property
• Highlighting changes
29

42. HTML Columns
• Create custom column in REST service (or use
existing view column) with HTML content
• Add Grid Column to display HTML content column
• Set Grid property escapeHTMLInData = false
• Not a good idea – vulnerable to XSS
30

43. Icon Columns
• Doesn’t work as pass-thru HTML
• Requires column formatter function (client JS)
• Formatter can conditionally return <IMG> tag
• Does not require escapeHTMLInData property
• Much more secure for all passthru HTML
31

44. Dojo EnhancedGrid
• Dojo module that extends DataGrid
• Already available on the server
• Provides enhanced features via plugins
• Check for available features based on Domino/Dojo
version
• Domino 8.5.3 – Dojo 1.6
• Domino 9 – Dojo 1.8
• http://dojotoolkit.org/reference-
guide/1.6/dojox/grid/EnhancedGrid.html
32

45. Converting to EnhancedGrid
• Dojo Data Grid control creates a Dojo DataGrid
• You can modify to create a Dojo EnhancedGrid
1. Load the EnhancedGrid module
2. Set grid Dojo type
3. Load required style sheets 33

46. Converting to EnhancedGrid
• 1 - Load the EnhancedGrid module on the page
• Resources > Add > Dojo Module
• dojox.grid.EnhancedGrid
34

47. Converting to EnhancedGrid
• 2 - Set grid Dojo type to dojox.grid.EnhancedGrid
• Properties > Dojo > Dojo type
35

48. Converting to EnhancedGrid
• 3 - Load required style sheets
• Load relative to the Domino server path
<xp:styleSheet
href="/.ibmxspres/dojoroot/dojox/grid/resources/Grid.css">
</xp:styleSheet>
<xp:styleSheet
href="/.ibmxspres/dojoroot/dojox/grid/resources/EnhancedGrid.css">
</xp:styleSheet>
36

49. Verify EnhancedGrid
37

50. EnhancedGrid Plugin - DnD
• Provides ability to drag and drop columns, rows,
and cells
• Configuration object defines options
• Add a row selector to drag and drop rows
• Usage
1. Select content to drag
2. Release mouse button
3. Click on the data to move it
• IMPORTANT: When cells are moved, changes are
automatically saved 38

51. EnhancedGrid Plugin - DnD
1. Load the DnD plugin
• Properties > Resources > Add > Dojo Module
• dojox.grid.enhanced.plugins.DnD
39

52. EnhancedGrid Plugin - DnD
2. Add plugin to grid as an attribute
• Dojo > Add
• Name: plugins
• Value: {dnd: {dndConfig:{} } }
• All selection types enabled by default
40

53. EnhancedGrid Plugin - Filter
• Adds a filter bar
• Up to 3 Filtering rules
• Match all rules or any rule
• Select column to filter
• Select matching condition (is, contains, starts with…)
• No coding required!!
• Results are sortable
41

54. EnhancedGrid Plugin - Filter
1. Load the Filter plugin
• Properties > Resources > Add > Dojo Module
• dojox.grid.enhanced.plugins.Filter
42

55. EnhancedGrid Plugin - Filter
2. Add plugin to grid as an attribute
• Dojo > Add
• Name: plugins
• Value: {filter: true}
43

56. EnhancedGrid Plugin - Filter
3. Add a stylesheet
<xp:styleSheet
href="/.ibmxspres/dojoroot/dojox/grid/enhanced/resources/claro/EnhancedGrid.css">
</xp:styleSheet>
44

57. EnhancedGrid – More Plugins
• Print
• Provides ability to preview or print grid contents
• Print/Preview All, Selected, Custom
• Exporter
• Provides grid data for export – you handle the rest
• Export All, Selected, Custom
• Menu
• Context menus for columns, rows, cells, selected
• Build with dijit menus and dijit menu items
45

58. Dojo TreeGrid
• Provides multi-level categorization
• Can provide column totals and counts
• Extends Dojo DataGrid
• Cannot use EnhancedGrid plugins
• Poor documentation
• Apparently cannot use Dojo Data Grid control
46

59. TreeGrid - Implementation
• Programmatic -- NOT the Dojo Data Grid Control
1. Include required dojo modules and stylesheets
2. Set XPage to parse dojo on load
3. Define a <div> to render the grid and size it
4. Execute code onClientLoad to configure and generate
the grid
5. Provide data for the grid (XAgent)
• Complicated format
...
{ id: 'AS', name:'Asia', type:'continent',
children:[{_reference:'CN'}, {_reference:'IN'}] },
{ id: 'CN', name:'China', type:'country' },
{ id: 'IN', name:'India', type:'country' },
...
47

60. TreeGrid – Totals and Counts
• Inline when collapsed, below when expanded
• Requires a different (but simpler) JSON model
{id:'AK', type: 'state', state:'AK', numPeople: 3,
childItems:[
{id:'B3093953178C98E905257838007ABC48', firstname:'Bella',
lastname: 'Martin', valueToAdd: 2},
{id:'7FDB9CCDE7D6923E05257838007ABC1E', firstname:'Brian',
lastname: 'Leggett', valueToAdd: 2}
] },
• Add an aggregate property
• Set to “sum” or “cnt”
• Numeric columns handled properly; text concatenated
• Formatter functions can modify display (and hide text)
48

61. TreeGrid – Data Format Caveat
• Simpler JSON format causes blank rows when used
without counts/totals
49

62. TreeGrid - Features
• defaultOpen – expanded or collapsed
• openAtLevels – auto expand all categories with less
items than the defined amount
• Doesn’t work with ForestStoreModel
• expandoCell – column to display expand icon
