DataBind MarkLogic Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for MarkLogic 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 User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with MarkLogic data. The MarkLogicDataAdapter 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 (MarkLogicConnection connection = new MarkLogicConnection( "User='myusername';Password='mypassword';Server='http://marklogic';")) { MarkLogicDataAdapter dataAdapter = new MarkLogicDataAdapter( "SELECT Name, TotalDue FROM Customer", 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[] { "TotalDue" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Name"; 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 MarkLogic data. The MarkLogicDataAdapter 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 (MarkLogicConnection connection = new MarkLogicConnection( "User='myusername';Password='mypassword';Server='http://marklogic';")) { MarkLogicDataAdapter MarkLogicDataAdapter1 = new MarkLogicDataAdapter("SELECT Name, TotalDue FROM Customer", connection); DataTable table = new DataTable(); MarkLogicDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "TotalDue" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
