I have a pie graph and want to map its items to two values in the detail section data. For example, if the report data has two columns COLUMN_ONE and COLUMN_TWO, how can I map two slices of a pie graph to those columns? Do I need to do it programmatically?
When I attempt to use the technique described at http://www.telerik.com/help/reporting/faq-combine-values2.html I get an error saying "Unable to cast object of type "DataObject" to type "System.Data.DataRow". So if I have a pie chart in a detail section, how can I assign its items values from the current DataRow?
