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

The CData ADO.NET Provider for Redis implements standard ADO.NET data access components that can be used with third-party controls. The standard ADO.NET process for databinding can be followed to enable bidirectional access to live data from UI controls. In this article we show how to use the CData components to databind to the DevExpress Windows Forms and Web controls; you will databind to a chart that displays current 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; }
