Chart Databinding

[Gary]

Hello all -

I'm currently evaluating Telerik Reporting and am attempting to create a simple chart.  I have a TableAdapter on the reporting surface as well as a Chart control.  When I bring up the ChartUI I am unable to databind it to the TableAdapter (I'm assuming this is possible?).  The following message is displayed: To dynamically populate the chart with data use the NeedDataSource event.

Is it not possible to define the databindings at design time rather than from within code-behind?  I'm sure I'm just doing something silly but if someone could shed some light on my problem that would be great!

Thanks!

Hello Gary,

Currently the Chart item does not support binding to data adapters. For the full list of supported data sources you can refer to the Data Binding Chart documentation article.

At this moment the NeedDataSource event is the only place where you can feed the chart with data. You can easily fill a DataSet or a DataTable object by using the design time generated data components. Here is an example:

        private void chart1_NeedDataSource(object sender, System.EventArgs e)
    {
       Telerik.Reporting.Processing.Chart chart =
                (Telerik.Reporting.Processing.Chart)sender;

       ChartDataSet.CurrencyRateDataTable dataTable = new ChartDataSet.CurrencyRateDataTable();
       ChartDataSetTableAdapters.CurrencyRateTableAdapter tableAdapter = new CurrencyRateTableAdapter();
       tableAdapter.Fill(dataTable);
       chart.DataSource = dataTable;
    }
