Does anyone know if its possible to use Json.NET's JObject as a source for graphs? I need to bind a dynamically typed objects in runtime.

In C#, I'm doing this as a POC:

 

var d = new { Missing = 60D, Flagged = 10D, Valid = 30D };        

var s = JsonConvert.SerializeObject(d);        

var j = JsonConvert.DeserializeObject(s);

var ds = new ObjectDataSource();             

ds.DataSource = data;             

var report = new Report1();             

report.MyPieGraph.DataSource = ds;

 

The report renders the graph, but only the legend, not the actual pie graph.

Hi Stefan,

Reports are 'strongly-typed'. Data must have a flatten tabular representation, where the report uses the discovered fields for design purposes. The object set as data source must contain the fields used in the report.

On processing a report the whole data must be available. You can use a data service and load data in a custom .NET business object as in Connecting Telerik Reporting to OData feeds. Then you can use an ObjectDataSource that will retrieve the data via data-access layer.

Please note that already instantiated data objects do not have to be wrapped in data source components - Do I need to use a Data Source component?


Let us know if you need further help.

Regards,
