This answers the question of how to set the report source. i.e. "SampleReport.trdp"
The original question was how to change the DataSource of a report. As in SQL command etc... There is no documentation of this for the newer HTML5 report viewer.
Example under the old reporting system:
Dimreport AsTelerik.Reporting.Report = DirectCast(xmlSerializer.Deserialize(xmlReader), Telerik.Reporting.Report)report.DataSource = GetData(strSRDID) SharedFunctionGetData(strSRDID AsString) AsIDataAdapter DimconnectionString AsString= ConfigurationManager.ConnectionStrings("BOSTradeConnectionString").ToString DimselectCommandText AsString= "SELECT fLoadSortStringText_1.SortString, dbo.tblScaleData.* FROM dbo.tblScaleData INNER JOIN dbo.fLoadSortStringText() AS fLoadSortStringText_1 ON dbo.tblScaleData.SRDID = fLoadSortStringText_1.SRDID WHERE (dbo.tblScaleData.SRDID IN ( "& strSRDID & "))" 'Dim selectCommandText As String = "select * from fLoadSortStringTable(" & strSRDID & ")" ReturnNewSqlDataAdapter(selectCommandText, connectionString)EndFunction
