DataBind Wijmo Grid to Azure Synapse Data


Provide real-time Azure Synapse data to interactive controls.

The Connect Server enables you to use Web services to connect to and query Azure Synapse data. This article details how to import an OData feed of Azure Synapse data into Wijmo Grid.

Configuring Connect Server

To work with live Azure Synapse data in Wijmo Grid, we need to connect to Azure Synapse from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Azure Synapse data.

Add a Connect Server User

Create a User to connect to Azure Synapse from Wijmo Grid through Connect Server.

  1. Click Users -> Add
  2. Configure a User
  3. Click Save Changes and make note of the Authtoken for the new user

Connect to Azure Synapse from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open Connect Server and click Connections
  2. Select "Azure Synapse" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Azure Synapse.

    Connecting to Azure Synapse

    In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

    • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
    • Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

    Authenticating to Azure Synapse

    Connect to Azure Synapse using the following properties:

    • User: The username provided for authentication with Azure.
    • Password: The password associated with the authenticating user.
  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Azure Synapse OData Endpoints in Connect Server

After connecting to Azure Synapse, create OData Endpoints for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the Azure Synapse database
  3. Select the table(s) you wish to work with and click Next
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Connect to Azure Synapse Data using Wijmo Grid

Create a Real-Time Grid

Follow the steps below to consume Azure Synapse data from the Wijmo JavaScript controls:

  1. Load the required Wijmo, jQuery, and Knockout libraries: 
    			
			<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
			<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.min.js"></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"></script>
					<script src="http://cdn.wijmo.com/jquery.wijmo-pro.all.3.20161.90.min.js"></script>
					<script src="http://cdn.wijmo.com/interop/wijmo.data.ajax.3.20161.90.js"></script>

					<!--Knockout JS Library-->
					<!-- Both of the links below can work -->
					<script src="http://cdn.wijmo.com/wijmo/external/knockout-2.2.0.js"></script>
					<!--<script src="http://cdn.wijmo.com/amd-js/3.20161.90/knockout-3.1.0.js"></script>-->

					<!--Wijmo Knockout Integration Library-->
					<script src="http://cdn.wijmo.com/interop/knockout.wijmo.3.20161.90.js"></script>
  2. Create a ViewModel and connect to it using the ODataView. You will need to replace the placeholder values for the URL of the API Server, an API Server user, and the authtoken for that user. 
    			
			<script id="scriptInit">
			$.support.cors = true;
			var viewModel;

			function ViewModel() {
			var productsView = new wijmo.data.ODataView("http://MyServer:MyPort/api.rsc/Products", {
			ajax: {
			dataType: "jsonp",
			username: "MyUser",
			password: "MyAuthtoken",
			data: { "$inlinecount": null }
			},
			pageSize: 10
			});
			productsView.refresh();
			productsView.nextPage();
			this.products = productsView;
			this.prevPage = function () {productsView.prevPage();};
			this.nextPage = function () {productsView.nextPage();};
			}

			$(document).ready(function () {
			viewModel = new ViewModel();
			ko.applyBindings(viewModel, $(".container").get(0));
			});
			</script>
  3. DataBind: Below is a simple table with some paging buttons, which you can paste into the body section of your markup. 
    			
			<h2>Connect to Live Azure Synapse Data in Real Time</h2>

			<h3>Products</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, 
      showFilter: true, 
      allowPaging: true,
      pagerSettings: { position: 'none'},
      columnsAutogenerationMode: 'append',
    }" >
			</table>

At this point, you may be prompted to re-enter the username and authtoken. After doing so, a resulting table or grid should appear, as seen below. You can filter and sort through pages of Azure Synapse data.
