DataBind Redis Data to the DevExpress Data Grid

The ADO.NET Provider for Redis 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.

Set the following connection properties to connect to a Redis instance:

• Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
• Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.

Set UseSSL to negotiate SSL/TLS encryption when you connect.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Redis data. The RedisDataAdapter 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 (RedisConnection connection = new RedisConnection(
"Server=127.0.0.1;Port=6379;Password=myPassword;")) {
  RedisDataAdapter dataAdapter = new RedisDataAdapter(
  "SELECT City, CompanyName FROM Customers", 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[] { "CompanyName" });
  series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
  series.ArgumentDataMember = "City";
  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 Redis data. The RedisDataAdapter 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 (RedisConnection connection = new RedisConnection(
"Server=127.0.0.1;Port=6379;Password=myPassword;"))
{
  RedisDataAdapter RedisDataAdapter1 = new RedisDataAdapter("SELECT City, CompanyName FROM Customers", connection);
  DataTable table = new DataTable();
  RedisDataAdapter1.Fill(table);
  DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
  WebChartControl1.Series.Add(series);
  series.DataSource = table;
  series.ValueDataMembers.AddRange(new string[] { "CompanyName" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "City";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
