DataBind Oracle SCM Data to the DevExpress Data Grid

The ADO.NET Provider for Oracle SCM 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 following connection properties are required to connect to Oracle SCM data.

• Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
• User: The username of your Oracle Cloud service account.
• Password: The password of your Oracle Cloud service account.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Oracle SCM data. The OracleSCMDataAdapter 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 (OracleSCMConnection connection = new OracleSCMConnection(
"Url=https://myinstance.oraclecloud.com;User=user;Password=password;")) {
 OracleSCMDataAdapter dataAdapter = new OracleSCMDataAdapter(
 "SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'", 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[] { "CarrierName" });
 series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
 series.ArgumentDataMember = "CarrierId";
 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 Oracle SCM data. The OracleSCMDataAdapter 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 (OracleSCMConnection connection = new OracleSCMConnection(
"Url=https://myinstance.oraclecloud.com;User=user;Password=password;"))
{
 OracleSCMDataAdapter OracleSCMDataAdapter1 = new OracleSCMDataAdapter("SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'", connection);
 DataTable table = new DataTable();
 OracleSCMDataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "CarrierName" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "CarrierId";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
