DataBind Avalara AvaTax Data to the DevExpress Data Grid

The ADO.NET Provider for Avalara AvaTax by CData incorporates conventional ADO.NET data access components compatible with third-party controls. You can adhere to the standard ADO.NET data binding procedures to establish two-way access to real-time data through UI controls. This article will demonstrate the utilization of CData components for data binding with DevExpress UI Controls (Windows Forms and Web controls), specifically binding to a chart that visualizes live data.

The primary method for performing basic authentication is to provide your login credentials, as follows:

• User: Set this to your username.
• Password: Set this to your password.

Optionally, if you are making use of a sandbox environment, set the following:

• UseSandbox: Set this to true if you are authenticating with a sandbox account.

Authenticating Using Account Number and License Key

Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

• AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
• LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account administrator and navigating to Settings -> Reset License Key.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Avalara AvaTax data. The AvalaraAvataxDataAdapter binds to the Series property of the chart control. The Diagram property of the control defines the x- and y-axes as the column names.

using (AvalaraAvataxConnection connection = new AvalaraAvataxConnection(
"User=MyUser;Password=MyPassword;")) {
 AvalaraAvataxDataAdapter dataAdapter = new AvalaraAvataxDataAdapter(
 "SELECT Id, TotalTax FROM Transactions WHERE Code = '051349'", connection);
 
 DataTable table = new DataTable();
 dataAdapter.Fill(table);
 DevExpress.XtraCharts.Series series = new DevExpress.XtraCharts.Series();
 chartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "TotalTax" });
 series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
 series.ArgumentDataMember = "Id";
 series.ValueScaleType = DevExpress.XtraCharts.ScaleType.Numerical;
 chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; 
}

Web Controls

The code below shows how to populate a DevExpress Web control with Avalara AvaTax data. The AvalaraAvataxDataAdapter binds to the Series property of the chart; the Diagram property defines the x- and y-axes as the column names.

using DevExpress.XtraCharts;

using (AvalaraAvataxConnection connection = new AvalaraAvataxConnection(
"User=MyUser;Password=MyPassword;"))
{
 AvalaraAvataxDataAdapter AvalaraAvataxDataAdapter1 = new AvalaraAvataxDataAdapter("SELECT Id, TotalTax FROM Transactions WHERE Code = '051349'", connection);
 DataTable table = new DataTable();
 AvalaraAvataxDataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "TotalTax" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "Id";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
