Hi,
I am using RDLC pie charts with Two slices...., if user Click on one slice it should take to another Report...,

protected void rptepaymentstatus_OnDrillthrough(object sender, DrillthroughEventArgs e)
       {

LocalReport report = (LocalReport)e.Report;
            string ststus = string.Empty;
            IList<ReportParameter> list = report.OriginalParametersToDrillthrough;
            foreach (ReportParameter param in list)
            {
                
                ststus = Convert.ToString(param.Values[0]);
            }
            try
            {
                DataTable OutPutData = new DataTable();
                OutPutData = ObjClsDashboard.GetEpayrpt(dtFromdate.SelectedDate, dttoDate.SelectedDate, ststus);
                DataTable dt = new DataTable();
                rptepaymentstatus.LocalReport.ReportEmbeddedResource = "@rptEpaymentStatus.rdlc";
                
                //rptepaymentstatus.LocalReport.ReportPath = @"rptEpaymentStatus.rdlc";
                rptepaymentstatus.LocalReport.DataSources.Clear();
                rptepaymentstatus.LocalReport.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource("DSEpayStatus", OutPutData));
                rptepaymentstatus.LocalReport.DataSources.Add(new Microsoft.Reporting.WebForms.ReportDataSource("DSEPMS", OutputData1));
                rptepaymentstatus.DocumentMapCollapsed = true;
