Databind Wijmo Grid to Salesforce.com Data

The CData API Server provides Salesforce data (along with 80+ other sources) as Web services, which enable connectivity to live data. This article shows how to consume JSONP-formatted Salesforce data from a Wijmo Grid.

1. If you have not already connected successfully in the administration console, see the "Getting Started" chapter in the help documentation for a guide.
2. Load the required Wijmo, jQuery, and Knockout libraries:

   <script class=lazyload data-src="http://code.jquery.com/jquery-1.11.1.min.js" type="text/javascript"></script>
   <script class=lazyload data-src="http://code.jquery.com/ui/1.11.0/jquery-ui.min.js" type="text/javascript"></script>
     
   <!--Theme-->
   <link href="http://cdn.wijmo.com/themes/aristo/jquery-wijmo.css" rel="stylesheet" type="text/css">
     
   <!--Wijmo Widgets CSS-->
   <link href="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.css" rel="stylesheet" type="text/css">
     
   <!--Wijmo Widgets JavaScript-->
   <script class=lazyload data-src="http://cdn.wijmo.com/jquery.wijmo-open.all.3.20161.90.min.js" type="text/javascript"></script>
   <script class=lazyload data-src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js" type="text/javascript"></script>
   <script class=lazyload data-src="http://cdn.wijmo.com/interop/wijmo.data.ajax.3.20161.90.js" type="text/javascript"></script>
    
   <!--Knockout JS Library-->
   <!-- Both of the links below can work -->
   <script class=lazyload data-src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js" type="text/javascript"></script> 
   <!--<script class=lazyload data-src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js" type="text/javascript"></script>--> 
   
   <!--Wijmo Knockout Integration Library-->
   <script class=lazyload data-src="http://cdn.wijmo.com/interop/knockout.wijmo.3.20161.90.js" type="text/javascript"></script>

3. Create a ViewModel and connect to it using the ODataView:

   <script id="scriptInit" type="text/javascript">
   $.support.cors = true;
   var viewModel;
   
   function ViewModel() {
     var AccountView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/Account", {
     ajax: {
       dataType: "jsonp", 
       username: "MyUser",
       password: "MyAuthtoken",
       data: { "$inlinecount": null }
     },
     pageSize: 10
   });
     accountView.refresh();
     accountView.nextPage();
     this.account = accountView;
     this.prevPage = function () {accountView.prevPage();};
     this.nextPage = function () {accountView.nextPage();};
   }
   
   $(document).ready(function () {
      viewModel = new ViewModel();
      ko.applyBindings(viewModel, $(".container").get(0));
   });
   </script>

4. Databind: Below is a simple table with some paging buttons, which you can paste into the body section of your markup.

   <h2>Edit Live Salesforce Data in Real Time</h2>
   
   <h3>Account</h3>
   <div>
     <button title="previous page" class="pagebuttons" data-bind="click: prevPage, button: {}"><span class="ui-icon ui-icon-seek-prev" /></button>
     <button title="next page" class="pagebuttons" data-bind="click: nextPage, button: {}"><span class="ui-icon ui-icon-seek-next" /></button>
   </div>
   <table id="demo-grid" data-bind="wijgrid: { 
     data: products, 
     allowEditing: true, 
     showFilter: true, 
     allowPaging: true,
     pagerSettings: { position: 'none'},
     columnsAutogenerationMode: 'append',
   }" >
   </table>

Below is the resulting grid. You can filter, sort, edit, and save. Paging makes working with large datasets manageable.
