Use the CData ADO.NET Provider for Xero WorkflowMax with the DevExpress Windows Forms and Web controls to provide Xero WorkflowMax data to a chart.
The ADO.NET Provider for Xero WorkflowMax 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.
To connect to the WorkflowMax API, obtain an APIKey and AccountKey from Xero. This can only be done by contacting Xero support (https://www.workflowmax.com/contact-us).
After obtaining an API Key and Account Key, set the values in the APIKey and AccountKey connection properties. Once these are set, you are ready to connect.
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Xero WorkflowMax data. The XeroWorkflowMaxDataAdapter 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 (XeroWorkflowMaxConnection connection = new XeroWorkflowMaxConnection(
"APIKey=myApiKey;AccountKey=myAccountKey;")) {
XeroWorkflowMaxDataAdapter dataAdapter = new XeroWorkflowMaxDataAdapter(
"SELECT Id, Name FROM Clients WHERE Name = 'Cynthia'", 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[] { "Name" });
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 Xero WorkflowMax data. The XeroWorkflowMaxDataAdapter 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 (XeroWorkflowMaxConnection connection = new XeroWorkflowMaxConnection(
"APIKey=myApiKey;AccountKey=myAccountKey;"))
{
XeroWorkflowMaxDataAdapter XeroWorkflowMaxDataAdapter1 = new XeroWorkflowMaxDataAdapter("SELECT Id, Name FROM Clients WHERE Name = 'Cynthia'", connection);
DataTable table = new DataTable();
XeroWorkflowMaxDataAdapter1.Fill(table);
DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
WebChartControl1.Series.Add(series);
series.DataSource = table;
series.ValueDataMembers.AddRange(new string[] { "Name" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "Id";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
