DataBind Azure Synapse Data to the DevExpress Data Grid

The ADO.NET Provider for Azure Synapse 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.

Connecting to Azure Synapse

In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

• Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
• Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

Authenticating to Azure Synapse

Connect to Azure Synapse using the following properties:

• User: The username provided for authentication with Azure.
• Password: The password associated with the authenticating user.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Azure Synapse data. The AzureSynapseDataAdapter 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 (AzureSynapseConnection connection = new AzureSynapseConnection(
"User=myuser;Password=mypassword;Server=localhost;Database=Northwind;")) {
 AzureSynapseDataAdapter dataAdapter = new AzureSynapseDataAdapter(
 "SELECT Id, ProductName FROM Products WHERE ProductName = 'Konbu'", 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[] { "ProductName" });
 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 Azure Synapse data. The AzureSynapseDataAdapter 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 (AzureSynapseConnection connection = new AzureSynapseConnection(
"User=myuser;Password=mypassword;Server=localhost;Database=Northwind;"))
{
 AzureSynapseDataAdapter AzureSynapseDataAdapter1 = new AzureSynapseDataAdapter("SELECT Id, ProductName FROM Products WHERE ProductName = 'Konbu'", connection);
 DataTable table = new DataTable();
 AzureSynapseDataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "ProductName" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "Id";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
