DataBind Superchat 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.
Superchat uses API Key authentication. The API key is passed via the X-API-KEY request header on every call.
Authentication
To authenticate to Superchat, you need to obtain your API key from the Superchat workspace settings.
Using API Key Authentication
You can obtain your API key from Settings > Integrations > API Key in your Superchat workspace.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to APIKey.
- APIKey: Set this to your Superchat API key.
Example connection string:
Profile=C:\profiles\Superchat.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Superchat 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\Superchat.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';")) {
APIDataAdapter dataAdapter = new APIDataAdapter(
"SELECT , FROM Channels WHERE = ''", 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[] { "" });
series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
series.ArgumentDataMember = "";
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 Superchat 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\Superchat.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';"))
{
APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT , FROM Channels WHERE = ''", 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[] { "" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
