DataBind Charts to Marketo Data

Use the standard ADO.NET procedures for databinding to provide bidirectional access to Marketo 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 enables bidirectional access to data from UI controls. You can use the CData ADO.NET Provider for Marketo to easily databind Marketo data to Windows Forms and Web controls in Visual Studio. This article shows how to use wizards to databind Marketo data to a chart that reflects any changes. The code walk-through section shows how to create a chart in 10 lines of code.

DataBind to a Chart

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

Configure the Connection and Select Database Objects

Follow the procedure below to use the Data Source Configuration Wizard to create a chart control and the connection to Marketo. In the wizard, you can select the Marketo entities you want to databind.

  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 Marketo Data Source.

    Below is a typical connection string:

    Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;

    Both the REST and SOAP APIs are supported and can be chosen by using the Schema property.

    For the REST API: The OAuthClientId, OAuthClientSecret, and RESTEndpoint properties, under the OAuth and REST Connection sections, must be set to valid Marketo user credentials.

    For the SOAP API: The UserId, EncryptionKey, and SOAPEndpoint properties, under the SOAP Connection section, must be set to valid Marketo user credentials.

    See the "Getting Started" chapter of the help documentation for a guide to obtaining these values.

    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 Leads 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 Email and the y-axis to AnnualRevenue.

  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 Marketo data. Run the chart to display the current data.

Code Walk-through

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

  1. Connect to Marketo.
  2. Create the MarketoDataAdapter 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:

MarketoConnection conn = new MarketoConnection("Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;"); MarketoCommand comm = new MarketoCommand("SELECT Email, AnnualRevenue FROM Leads", conn); MarketoDataAdapter da = new MarketoDataAdapter(comm); DataSet dataset = new DataSet(); da.Fill(dataset); chart1.DataSource = dataset; chart1.Series[0].XValueMember = "Email"; chart1.Series[0].YValueMembers = "AnnualRevenue"; // Insert code for additional chart formatting here. chart1.DataBind();
