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 src="http://code.jquery.com/jquery-1.11.1.min.js" type="text/javascript"></script>
    <script 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 src="http://cdn.wijmo.com/jquery.wijmo-open.all.3.20161.90.min.js" type="text/javascript"></script>
    <script src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js" type="text/javascript"></script>
    <script 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 src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js" type="text/javascript"></script> 
    <!--<script src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js" type="text/javascript"></script>--> 
    
    <!--Wijmo Knockout Integration Library-->
    <script 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.
