DataBind Charts to Couchbase Data

Use the standard ADO.NET procedures for databinding to provide bidirectional access to Couchbase 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 Couchbase to easily databind Couchbase data to Windows Forms and Web controls in Visual Studio. This article shows how to use wizards to databind Couchbase 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


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 Couchbase. In the wizard, you can select the Couchbase entities you want to databind.

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

    Below is a typical connection string:


    To connect using the Login method, set User, Password, and Server to the credentials for the account and the address of the server you want to connect to.




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


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

Code Walk-through

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

  1. Connect to Couchbase.
  2. Create the CouchbaseDataAdapter 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:

CouchbaseConnection conn = new CouchbaseConnection("User=myuseraccount;Password=mypassword;Server=http://mycouchbaseserver;"); CouchbaseCommand comm = new CouchbaseCommand("SELECT Contact.FirstName, SUM(Account.TotalDue) FROM Contact, Account GROUP BY Contact.FirstName", conn); CouchbaseDataAdapter da = new CouchbaseDataAdapter(comm); DataSet dataset = new DataSet(); da.Fill(dataset); chart1.DataSource = dataset; chart1.Series[0].XValueMember = "FirstName"; chart1.Series[0].YValueMembers = "TotalDue"; // Insert code for additional chart formatting here. chart1.DataBind();
