Get the Report →DataBind Azure Data Catalog Data to the DevExpress Data Grid
Use the CData ADO.NET Provider for Azure Data Catalog with the DevExpress Windows Forms and Web controls to provide Azure Data Catalog data to a chart.
The ADO.NET Provider for Azure Data Catalog 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.
You can optionally set the following to read the different catalog data returned from Azure Data Catalog.
- CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name
Connect Using OAuth Authentication
You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Azure Data Catalog data. The AzureDataCatalogDataAdapter 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 (AzureDataCatalogConnection connection = new AzureDataCatalogConnection(
"InitiateOAuth=GETANDREFRESH")) {
AzureDataCatalogDataAdapter dataAdapter = new AzureDataCatalogDataAdapter(
"SELECT DslAddressDatabase, Type FROM Tables WHERE Name = 'FactProductInventory'", 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[] { "Type" });
series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
series.ArgumentDataMember = "DslAddressDatabase";
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 Azure Data Catalog data. The AzureDataCatalogDataAdapter 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 (AzureDataCatalogConnection connection = new AzureDataCatalogConnection(
"InitiateOAuth=GETANDREFRESH"))
{
AzureDataCatalogDataAdapter AzureDataCatalogDataAdapter1 = new AzureDataCatalogDataAdapter("SELECT DslAddressDatabase, Type FROM Tables WHERE Name = 'FactProductInventory'", connection);
DataTable table = new DataTable();
AzureDataCatalogDataAdapter1.Fill(table);
DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
WebChartControl1.Series.Add(series);
series.DataSource = table;
series.ValueDataMembers.AddRange(new string[] { "Type" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "DslAddressDatabase";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
