Use the CData ADO.NET Provider for Redis with the DevExpress Windows Forms and Web controls to provide Redis data to a chart.

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; }
