ig.DataSource

ig.DataSource_image

The igDataSource component is a client-side component which features support for filtering, paging, sorting, summaries, and updating data. The component also provides hierarchical data binding and load-on-demand support for the igHierarchicalGrid and igTree controls. Supports is also available for binding to various types of data sources including JSON, XML, HTML tables, WCF/REST services, JSONP and JSONP and OData combined. Other classes which extend the data source base class come preconfigured with specified data types which  include: igArrayDataSource, igFunctionDataSource, igHtmlTableDataSource, igJSONDataSource, igJSONPDataSource, igRemoteDataSource, and igXmlDatasource. Further information regarding the classes, events, methods and themes of this API are available under the associated tabs above.

The following code snippet demonstrates how to initialize the DataSource control.

    The Infragistics Data Source client-side component is implemented as a class, and has support for paging, sorting, and filtering
    it supports binding to various types of data sources including JSON, XML, HTML Table, WCF/REST services, JSONP, JSONP and OData combined, etc.

    Code Sample

     
    			var render = function (success, error) {
    				if (success) {
    					var template = "<tr><td>${Name}</td><td>${Price}</td><td>${Rating}</td></tr>",
    					resultHtml = $.ig.tmpl(template, ds.dataView());
    					$("#table").html(resultHtml);
    				} else {
    					alert(error);
    				}
    			}
    
    			var ds;
    
    			$(window).load(function () {
    			var url = "http://services.odata.org/OData/OData.svc/Products?$format=json&$callback=?";
    			ds = new $.ig.DataSource({
    			callback: render,
    			dataSource: url,
    			schema: {
    				fields: [{
    					name: "Name"
    				}, {
    					name: "Price"
    				}, {
    					name: "Rating"
    				}],
    					searchField: "d"
    			},
    			responseDataKey: "d",
    			responseDataType: "jsonp",
    			filtering: {
    				type: "remote",
    				filterExprUrlKey: "filter",
    				expressions: [{
    					fieldName: "Name",
    					cond: "Contains",
    					expr: "Cr"
    				}]
    			},
    			paging: {
    				enabled: true,

    • aggregateTransactions

      Type:
      bool
      Default:
      false

      If set to true, the following behavior will take place:
      if a new row is added, and then deleted, there will be no transaction added to the log
      if an edit is made to a row or cell, then the value is brought back to its original value, the transaction should be removed
      Note: This option takes effect only when autoCommit is set to false.

      Code Sample

       
      				var ds = new $.ig.DataSource({
      					aggregateTransactions: true,
      					dataSource: arrayOfObjects
      				});
      			 
    • autoCommit

      Type:
      bool
      Default:
      false

      If auto commit is true, data will be automatically commited to the data source, once a value or a batch of values are updated via saveChanges().

      Code Sample

       
      				var ds = new $.ig.DataSource({
      					autoCommit: true
      				});
      			 
    • callback

      Type:
      function
      Default:
      null

      				var render = function (success, error) {
      					if (success) {
      						alert("success");
      					} else {
      						alert(error);
      					}
      				}
      
      				$(window).load(function () {
      					var url = "http://odata.netflix.com/Catalog/Titles?$format=json&$callback=?";
      					ds = new $.ig.DataSource({
      						type: "remoteUrl",
      						callback: render,
      						dataSource: url,
      						schema: oDataSchema,
      						responseDataKey : "d.results",

  • dataBind

    .dataBind( [callback:string], [callee:object] );

    Data binds to the current data source
    databinding works using the following workflow:
    1. fire the databinding event
    2. based on the data source type (see analyzeDataSource()), do the following:
    3. if type is HtmlTable, parse the table and set the data and dataView respectively.
    if the type is Function, call it, apply Paging/Filtering/Sorting, and set this._dataView . If the developer wants to do his own paging, filtering or sorting
    in that case, then he should handle the PageIndexChanging and/or DataFiltering, and/or ColumnSorting client-side events, and cancel them.
    if no paging/sorting/filtering are enabled, use just this._data to save space
    if the data source is of type RemoteUrl, use jQuery's $.ajax API to trigger a remote request to the service. Use the param() API to encode the URL
    if the data source is invalid, throw an exception
    if the analyzed runtime data source type , that is, the result of analyzeDataSource(), is Unknown, check if
    the value of settings.type is set to XML or JSON. If string, eval for JSON, and parse for the XML to build the object tree
    4. now normalize/transform the data, if a schema is supplied. This inplies any additional data type conversion
    5. next, if OpType is Local, apply paging, sorting, and/or filtering to the data, and store the result in this._dataView
    6. fire the databound event.

  • filter

    .filter( fieldExpressions:object, boolLogic:object, keepFilterState:bool, fieldExpressionsOnStrings:object );

    Filters the data source locally. Remote filtering can be performed by just calling dataBind() and
    setting the settings.filtering.expressions. The result (filtered data) can be obtained by calling dataView()
    example: [{fieldName : "firstName", expr: "abc", cond: "StartsWith"}, {fieldName : "lastName"}]
    example 2: [{fieldIndex : 1} , {fieldIndex : 2, expr: "a", cond : "contains"}]
    example 3: [{filterAllFields: true, expr: "abc", fields: [name: "Description", type: "string"]}]
    expr is the filter expression text , such as "abc", or a regular expression such as *test*
    cond is the filtering condition such as startsWith, endsWith, contains, equals, doesNotEqual, doesNotContain
    if expr is detected to be a regular expression, the "cond" part is skipped
    To filter by text "fieldExpressions" should have only one object with the following schema:
    {filterAllFields: <type="bool" should be set to true>, expr: <type="string" the text to search for>, fields: <type="array" an array of fields to search in>}.

    • fieldExpressions
    • Type:object
    • a list of field expression definitions.
    • boolLogic
    • Type:object
    • boolean logic. Accepted values are AND and OR.
    • keepFilterState
    • Type:bool
    • if keepFilterState is set to true, it will not discard previous filtering expressions.
    • fieldExpressionsOnStrings
    • Type:object
    • a list of field expression definitions (or a string with the conditions separated by AND/OR operator, example: "ID = 1 OR ID = 2"), which when applied will threat the related field as if it's string and can only apply conditions valid for string types.

    Code Sample

     
    				ds = new $.ig.DataSource({
