DataBind Excel Data to the DevExpress Data Grid

The ADO.NET Provider for Excel 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.

The ExcelFile, under the Authentication section, must be set to a valid Excel File.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Excel data. The ExcelDataAdapter 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 (ExcelConnection connection = new ExcelConnection(
"Excel File='C:/MyExcelWorkbooks/SampleWorkbook.xlsx';")) {
  ExcelDataAdapter dataAdapter = new ExcelDataAdapter(
  "SELECT Name, Revenue FROM Sheet", 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[] { "Revenue" });
  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 Excel data. The ExcelDataAdapter 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 (ExcelConnection connection = new ExcelConnection(
"Excel File='C:/MyExcelWorkbooks/SampleWorkbook.xlsx';"))
{
  ExcelDataAdapter ExcelDataAdapter1 = new ExcelDataAdapter("SELECT Name, Revenue FROM Sheet", connection);
  DataTable table = new DataTable();
  ExcelDataAdapter1.Fill(table);
  DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
  WebChartControl1.Series.Add(series);
  series.DataSource = table;
  series.ValueDataMembers.AddRange(new string[] { "Revenue" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "Name";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
