DataBind Timely Data to the DevExpress Data Grid
The CData API Driver for ADO.NET 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.
Start by setting the Profile connection property to the location of the Timely Profile on disk (e.g. C:\profiles\Timely.apip). Next, set the ProfileSettings connection property to the connection string for Timely (see below).
Timely API Profile Settings
Register an OAuth application through your Timely account under Settings > Devs > New Application to obtain your Client ID and Client Secret.
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Timely data. The APIDataAdapter 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 (APIConnection connection = new APIConnection(
"Profile=C:\profiles\Timely.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;")) {
APIDataAdapter dataAdapter = new APIDataAdapter(
"SELECT Id, Name FROM Accounts WHERE Status = 'Active'", 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 Timely data. The APIDataAdapter 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 (APIConnection connection = new APIConnection(
"Profile=C:\profiles\Timely.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;"))
{
APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT Id, Name FROM Accounts WHERE Status = 'Active'", connection);
DataTable table = new DataTable();
APIDataAdapter1.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;
}
