Dear Friends,
 
Here in DrillDown Report iam facing the Problem.The Problem is Actually iam placing the Reportviewer in TabControl and Dynamically binding the Report view in tabcontrol.In parent Report iam Using the DrillDown Concept and navigate the page to another tab.The data is binding Perfectly in this Two Tabs.But when the Page is Drilldown the Parent Reportview is loosing the path.If i click the back Button its working fine.When i Drill down the Reportviewer from one tab to another tab the Problem is Coming.The parent Reportviewer is loosing his path.
Iam pasting my Code below if i done any thing wrong please rectify it.
