Concatenating DataLabelsColumn for pie chart

[Richard]

I have a datatable that I am using to populate a pie chart.  It has two columns Fund and Amount.  I want the labels to populate with the Fund name AND the #%...i.e. "American Funds 10%"

The problem I am having is retrieving the Fund name from the data row.  My chart uses a table adapter as the datasource.

private void chart1_NeedDataSource(object sender, EventArgs e)
        {
            Telerik.Reporting.Processing.Chart chart = sender as Telerik.Reporting.Processing.Chart;
            chart.DataSource = this.richPlayDBDataSetTableAdapter1.GetData(Convert.ToString(chart.Report.Parameters["SSN"]));


            DataRowView row = (DataRowView)chart.DataItem;

            Telerik.Reporting.Chart defChart = (Telerik.Reporting.Chart)chart.ItemDefinition;
            defChart.Series[0].DefaultLabelValue = string.Format("{0} #%", row["Fund"]);
        }

I keep getting "Object reference not set to an instance of an object" error.  The above code works perfectly if I substitute row["fund"] for just a normal string. How can I capture the actual row value?

Hello Richard,

The DataItem property is obsolete - please use DataObject instead. This KB article should shed more light on the changes introduced in the Q1 release.
