I was creating a new report which having sub-report.
After final update for telerik report 188.8.131.526 (Capture_3).
But i couldn't find the tool sub-report in toolbox on designer page (Capture_2).
And later i have noticed that the report designed before the update when i was using telerik report version Q3 of 2012,
now showing the error on opening that page as shown in attached file below (Capture_1).
Does telerik removed the sub report option from the designer or any other tool is there same as sub report.
