Value Report.Parameter not passed in Q1 2013?

[Ferry Engels]

Hello,

I just made a simple report which use a report.parameter to select some data.
The parameter is filled through a DataSouce with a Name and a Id field.
When i switch to preview the parameter box is filled and i can select a name from it.
Then clicking the Preview button a empty report is shown.
The value of the parameter is not passed or, when a extract the value from the parameter.value there is nothing.
I do this in the NeedDataSource Event before building the query.

Dim Id As String = Report.ReportParameters("Parameter1").Value.ToString

This worked before in older reports but now, whatever i try there is no value.
Is something changed??

I'm glad if somebody can help me before i spent a lot of time on something changed or a bug.

Regards,

Ferry

Kind of difficult to figure out the problem without code.

You have to use the report processing parameters.

//Take the Telerik.Reporting.Processing.Report instance
   Telerik.Reporting.Processing.Report report = (Telerik.Reporting.Processing.Report)sender;

   // Transfer the value of the processing instance of ReportParameter
   report.Parameters["ManagerID"].Value;

Yes that works in the needdatasouce event of the report.
Not in the needdatasource event of the crosstab.
Before Q1 2013 no problem but now it returns nothing.

Someone any idea?

Hi everyone,

As described in the Using Report Events help article, current report parameters values can be get in events from the processing equivalent of the report as shown in the following code snippet:

//Take the Telerik.Reporting.Processing.Table instance
   var table= (Telerik.Reporting.Processing.Table)sender;

   // Transfer the value of the Report processing instance of ReportParameter
   table.Report.Parameters["ManagerID"].Value;
