Hello Valik,

The issue is that at run-time, you create an instance of the report and then you set the report's DataSource property instead of the nested Table item's DataSource property. The result is repeating Detail section with empty Table item - Repeating data problem.


At run-time you can use the Find method to get the nested table item and to update its DataSource property e.g.:
//get the data object - there is no need to use a Data Source component in such case
//http://www.telerik.com/support/kb/reporting/accessing-and-managing-data/details/do-i-need-to-use-a-data-source-component
var data = GetData();
 
//create a new report instance
var report = new Report2();
//get the nested table item by name
var table = report.Items.Find("table1",true)[0] as Telerik.Reporting.Table;
table.DataSource = data;
 
//wrap[ the modified report instance
var IRS = new InstanceReportSource {Reportdocument = report}


Let us know if you need further help.

Regards,
Stef
