Tally ADO.NET Provider
Rapidly create and deploy powerful .NET applications that integrate with Tally.
Use the CData ADO.NET Provider for Tally with the DevExpress Windows Forms and Web controls to provide Tally data to a chart.
The CData ADO.NET Provider for Tally implements standard ADO.NET data access components that can be used with third-party controls. The standard ADO.NET process for databinding can be followed to enable bidirectional access to live data from UI controls. In this article we show how to use the CData components to databind to the DevExpress Windows Forms and Web controls; you will databind to a chart that displays current data.
Set the following connection properties to connect to Tally Instance:
- Url: Set this to the URL for your Tally instance. For example: http://localhost:9000.
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Tally data. The TallyDataAdapter 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 (TallyConnection connection = new TallyConnection(
"Url='http://localhost:9000'")) {
TallyDataAdapter dataAdapter = new TallyDataAdapter(
"SELECT Name, Address FROM Company WHERE CompanyNumber = '1000'", 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[] { "Address" });
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 Tally data. The TallyDataAdapter 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 (TallyConnection connection = new TallyConnection(
"Url='http://localhost:9000'"))
{
TallyDataAdapter TallyDataAdapter1 = new TallyDataAdapter("SELECT Name, Address FROM Company WHERE CompanyNumber = '1000'", connection);
DataTable table = new DataTable();
TallyDataAdapter1.Fill(table);
DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
WebChartControl1.Series.Add(series);
series.DataSource = table;
series.ValueDataMembers.AddRange(new string[] { "Address" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "Name";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
