Can I get the ReportParameters via Reflection?

Hi there,

currently I am working on a project to create custom reports.
I do that in this way:
I created a WCF-Service with a method which returns a Stream. This stream is the custom report, rendered to a pdf that is shown in a RadPDFViewer.
I do that because we need to send a list of all Reports that should be merged to one reportbook where every report is one single site with different data.
To create one report, I use this function:

public Report GetReport(ReportEntry entry)

{

dynamic newReport = new Object();

string parameterNameWithError = string.Empty;

string parameterValue = string.Empty;

string parameterType = string.Empty;

try

{

Type reportType = Type.GetType("ReportingService.Reports." + entry.Name);

newReport = Activator.CreateInstance(reportType);

foreach (var para in entry.ParameterList)

{

parameterNameWithError = para.Name;

parameterValue = para.Value;

parameterType = para.Type;

newReport.ReportParameters[para.Name].Value = para.Value;

}

catch (Exception ex)

{

newReport = new Reports.ErrorReport();

newReport.ReportParameters["ReportName"].Value = entry.Name;

newReport.ReportParameters["ParameterName"].Value = parameterNameWithError;

newReport.ReportParameters["ParameterValue"].Value = parameterValue;

newReport.ReportParameters["ParameterType"].Value = parameterType;

newReport.ReportParameters["ErrorMessage"].Value = ex.Message;

}

return newReport;

}

Now I want to create a function that gives me a list of all available reports with its ReportParameters.
I already get a list of reports, but I am now looking for a way to get the parameters.
This is what I have at the moment:

Type[] classes = Assembly.GetExecutingAssembly().GetExportedTypes();

foreach (Type t in classes)

{

if (t.FullName.Contains("Reports.Report"))

{

PropertyInfo[] props = t.GetProperties();

foreach(var prop in props)

{

if(prop.Name.Equals("ReportParameters"))

{

// What should I do here ???

}

Any kind of idea or hint?

Best Regards
Manfred

Custom Report Serialization

Hi,

Please could you give me some advice on the following. We are developing an application that will allow users to define their own custom reports that will be generated from our application data. The proposal is to simply allow the user to specify the grouping and column details that they wish to include in the report and then save their selection. A report would then be produced using telerik reporting based on the details they have selected.

One approach that we have considered to implement the above would be to create an xml file to generate the report from. This xml would be based on the xml generated by the telerik report serialization method, which would allow us then to create the report by deserializing the report using the telerik methods.

The thinking behind the above is that it would create a clean method of storing (they need to be saved for re-use and further amendments of the grouping/fields) and generating the report based on the same xml source. Do you think that this would be acceptable way of generating our reports?

Also is there any documentation defining the telerik xml file format, and is this format likely to change and potentially break any files we create?

Thanks

Q3 2012 Charting on Azure

Having a problem with charts when deployed to a server on Azure. It seems any chart put on a report will cause an error:

An error has occurred while processing Chart 'chart1': Parameter is not valid.

The chart is a completely unconfigured chart. No data. Nothing, but it causes an error just being there. If the chart is removed the report works properly.

The same report works locally, deployed to IIS, and testing in Azure Compute Fabric locally, but will not work when deployed to production.

The instance is configured to run framework 4.5, using the free cloud websites program. (Which should make it easy for testing)

Telerik Report Not Receiving Parameters

Hello Everyone,

I just upgraded to the new version of Telerilk Reporting yesterday (6.2.13.110) and now when I pass my parameters in my code behind the parameters aren't being excepted. This worked in the version prior to this one and I'm not sure what has changed.

Here is my code that I was using previously to dynamically changed the parameters on the fly:

Private Sub _GenerateReport()

Dim SeasonReport As New CISReports.NBA_PlayerShotChart()

' perform additional operations on the report object if needed

Dim SeasonInstanceReportSource As New Telerik.Reporting.InstanceReportSource()

SeasonInstanceReportSource.ReportDocument = SeasonReport

Me.ReportViewer1.ReportSource = SeasonInstanceReportSource

Dim SeasonReportSource = Me.ReportViewer1.ReportSource

SeasonReportSource.Parameters.Add("Season", CInt(cmbSeason.SelectedValue))

SeasonReportSource.Parameters.Add("SeasonTypeID", CInt(cmbSeasonType.SelectedValue))

SeasonReportSource.Parameters.Add("TeamAbbr", cmbTeams.SelectedValue)

SeasonReportSource.Parameters.Add("PlayerID", CInt(cmbPlayer.SelectedValue))

End Sub

Any help would be greatly appreciated since my reports are quite useless without the ability to dynamically change the parameters.

Thanks,

Brad
