DataBind Charts to ServiceNow Data


Use the standard ADO.NET procedures for databinding to provide bidirectional access to ServiceNow data from controls in the Visual Studio toolbox. This article demonstrates a graphical approach using wizards in Visual Studio, as well as how to databind with only a few lines of code.

DataBinding facilitates two-way interaction with data through UI controls. Using the CData ADO.NET Provider for ServiceNow streamlines the process of binding ServiceNow data to Windows Forms and Web controls within Visual Studio. In this article, we will demonstrate using wizards to establish a binding between ServiceNow data and a chart that dynamically updates. Additionally, the code walk-through section will guide you through the creation of a chart using just 10 lines of code.

About ServiceNow Data Integration

CData simplifies access and integration of live ServiceNow data. Our customers leverage CData connectivity to:

  • Get optimized performance since CData uses the REST API for data and the SOAP API for schema.
  • Read, write, update, and delete ServiceNow objects like Schedules, Timelines, Questions, Syslogs and more.
  • Use SQL stored procedures for actions like adding items to a cart, submitting orders, and downloading attachments.
  • Securely authenticate with ServiceNow, including basic (username and password), OKTA, ADFS, OneLogin, and PingFederate authentication schemes.

Many users access live ServiceNow data from preferred analytics tools like Tableau, Power BI, and Excel, and use CData solutions to integrate ServiceNow data with their database or data warehouse.


Getting Started


Binding Data to a Chart

DataBinding to a Chart consists of three steps: Instantiate the control, configure the data source, and databind.

Configure the Connection and Select Database Objects

To create a chart control and establish a connection to ServiceNow, follow the steps outlined below using the Data Source Configuration Wizard. Within the wizard, you'll have the option to choose the specific ServiceNow entities you wish to bind to.

  1. In a Windows Forms project, drag and drop a Chart control from the toolbox to the form. In the Data section of the Chart properties, select DataSource and then select Add Project Data Source from the menu.
  2. In the Data Source Configuration Wizard that appears, select Database -> Dataset.
  3. In the Choose Your Data Connection step, click New Connection.

  4. In the Add Connection dialog, click Change to select the CData ServiceNow Data Source.

    Below is a typical connection string:

    OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Username=MyUsername;Password=MyPassword;URL=https://myinstance12345.service-now-com;InitiateOAuth=GETANDREFRESH

    ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

    See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

    When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

  5. Choose the database objects you want to work with. This example uses the incident table.

DataBind

After adding the data source and selecting database objects, you can bind the objects to the chart. This example assigns the x-axis to sys_id and the y-axis to priority.

  1. In the Chart properties, click the button in the Series property to open the Series Collection Editor.
  2. In the Series properties, select the columns you want for the x- and y-axes: Select columns from the menu in the XValueMember and YValueMember properties.

The chart is now databound to the ServiceNow data. Run the chart to display the current data.

Code Walk-through

DataBinding to ServiceNow data requires only a few lines of code and can be completed in three easy steps.

  1. Connect to ServiceNow.
  2. Create the ServiceNowDataAdapter to execute the query and create a DataSet to be filled with its results.
  3. DataBind the result set to the chart.

Below is the complete code:

ServiceNowConnection conn = new ServiceNowConnection("OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Username=MyUsername;Password=MyPassword;URL=https://myinstance12345.service-now-com;InitiateOAuth=GETANDREFRESH"); ServiceNowCommand comm = new ServiceNowCommand("SELECT sys_id, priority FROM incident", conn); ServiceNowDataAdapter da = new ServiceNowDataAdapter(comm); DataSet dataset = new DataSet(); da.Fill(dataset); chart1.DataSource = dataset; chart1.Series[0].XValueMember = "sys_id"; chart1.Series[0].YValueMembers = "priority"; // Insert code for additional chart formatting here. chart1.DataBind();
