DataBind Reckon Accounts Hosted Data to the DevExpress Data Grid

The ADO.NET Provider for Reckon Accounts Hosted 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 connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

• SubscriptionKey: Required. You get this value when you created your developer account.
• CountryVersion: Defaults to 2021.R2.AU.
• CompanyFile: Required. The path to the company file.
• User: Required. The username of the company file.
• Password: Required. The password of the company file.
• InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
• CallbackURL: The redirectURI of your Custom OAuth App.
• OAuthClientId: The client id of your Custom OAuth App.
• OAuthClientSecret: The client secret of your Custom OAuth App.

CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Reckon Accounts Hosted data. The ReckonAccountsHostedDataAdapter 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 (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(
"SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;")) {
 ReckonAccountsHostedDataAdapter dataAdapter = new ReckonAccountsHostedDataAdapter(
 "SELECT Name, Balance FROM Accounts WHERE IsActive = 'true'", 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[] { "Balance" });
 series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
 series.ArgumentDataMember = "Name";
 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 Reckon Accounts Hosted data. The ReckonAccountsHostedDataAdapter 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 (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(
"SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;"))
{
 ReckonAccountsHostedDataAdapter ReckonAccountsHostedDataAdapter1 = new ReckonAccountsHostedDataAdapter("SELECT Name, Balance FROM Accounts WHERE IsActive = 'true'", connection);
 DataTable table = new DataTable();
 ReckonAccountsHostedDataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "Balance" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "Name";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
