New Title In Thread : Error/bug In ASMX ? - Parameters And Toolbar Property In DevInfo

Hi all,



I am trying to build a reportviewer so that I could use reporting services (due to company's security policy).



I am getting a VERY weird error here.



Before I get on ahead, here is the scenario.

I had created a rdl that will give a certain report based on two parameters. At the moment, I didn't assign the parameters to any default values since i don't want the report to start running. These two parameters are run based on stored procedures to get the starting date and an ending date.



I had tried to view this report on Report Manager and it works.



I had set the parameters this way. NOTE: ReportingServer is the disgused name of the reportserver I am using for privacy purposes




Code Snippet

Dim rs As New ReportingServer.ReportingService

rs.Credentials = System.Net.CredentialCache.DefaultCredentials

'Render arguments

Dim results() As Byte

Dim format As String = "HTML4.0"

Dim historyID As String = Nothing

'PDF Rendering extensions don't have any useful DeviceInfo settings

'the toolbar shown below only affects HTML rendering

Dim devInfo As String = "<DeviceInfo><HTMLFragment>True</HTMLFragment><JavaScript>True</JavaScript><Toolbar>True</Toolbar><Parameters>True</Parameters></DeviceInfo>"

Dim credentials() As ReportingServer.DataSourceCredentials = New ReportingServer.DataSourceCredentials() {}

Dim showHideToggle As String = ""

Dim encoding As String = ""

Dim mimeType As String = ""

Dim warnings() As ReportingServer.Warning = New ReportingServer.Warning(0) {}

Dim reportHistoryParameters() As ReportingServer.ParameterValue = New ReportingServer.ParameterValue() {}

Dim streamIDs() As String = Nothing

Dim sh As ReportingServer.SessionHeader = New ReportingServer.SessionHeader

rs.SessionHeaderValue = sh





But when I started building this reportviewer.aspx, it gives me this error on the following line:-






Code Snippet

results = rs.Render(ReportPath, format, historyID, devInfo, Parameters, credentials, _

showHideToggle, encoding, mimeType, reportHistoryParameters, warnings, streamIDs)









with the error



{"This report requires a default or user-defined value for the report parameter 'start_date'. To run or subscribe to this report, you must provide a parameter value. --> This report requires a default or user-defined value for the report parameter 'start_date'. To run or subscribe to this report, you must provide a parameter value. --> This report requires a default or user-defined value for the report parameter 'start_date'. To run or subscribe to this report, you must provide a parameter value."}



this is occuring on the line where it needs to render the report.



As simple as it is, i tried the following:-

NOTE: some variables has been changed to protect some identity.






Code Snippet

Dim ReportRenderer As New RenderSQLReports

Dim Parameters As int.rrd.sqlreporting_test.ParameterValue() = Nothing



ReportRenderer.RenderReport(Parameters, "/Folder/reportname", "pdffilename.pdf")









What I don't get is that i made sure that it doesn't have any default values.



So I went into this scenario and tried teh following:-






Code Snippet

Dim ReportRenderer As New RenderSQLReports

Dim Parameters() As Reportingservices.ParameterValue = New Reportingservices.ParameterValue(1) {}


Parameters(0) = New Reportingservices.ParameterValue

Parameters(0).Label = "start_date"

Parameters(0).Name = "start_date"

Parameters(0).Value = "10/1/1999 12:00:00 AM"

Parameters(1) = New Reportingservices.ParameterValue

Parameters(1).Label = "end_date"

Parameters(1).Name = "end_date"

Parameters(1).Value = "11/1/1999 12:00:00 AM"



ReportRenderer.RenderReport(Parameters, "/Folder/reportname", "pdffilename.pdf")







And this is what happens. It blows up on this line again. with this error.


Code Snippet

results = rs.Render(ReportPath, format, historyID, devInfo, Parameters, credentials, _

showHideToggle, encoding, mimeType, reportHistoryParameters, warnings, streamIDs)

With the errors



{"Default value or value provided for the report parameter 'start_date' is not a valid value. --> Default value or value provided for the report parameter 'start_date' is not a valid value. --> Default value or value provided for the report parameter 'start_date' is not a valid value."}



This is probably occuring because the date I had provided is not found in the list of dates. I really don't want to default a date at the moment, to allow the user to select a date.



So I finally gave it a date...... a valid date.






Code Snippet

Dim ReportRenderer As New RenderSQLReports

Dim Parameters() As Reportingservices.ParameterValue = New Reportingservices.ParameterValue(1) {}


Parameters(0) = New Reportingservices.ParameterValue

Parameters(0).Label = "start_date"

Parameters(0).Name = "start_date"

Parameters(0).Value = "10/1/2004 12:00:00 AM"

Parameters(1) = New Reportingservices.ParameterValue

Parameters(1).Label = "end_date"

Parameters(1).Name = "end_date"

Parameters(1).Value = "11/1/2004 12:00:00 AM"



ReportRenderer.RenderReport(Parameters, "/Folder/reportname", "pdffilename.pdf")



LO and behold, it works BUT . now i get this error in the aspx code.

Runtime error has occured.


Microsoft JScript runtime error: 'Report' is undefined

on this weird line:- (that was generated automatically)



</script><script language="javascript" type="text/javascript" src="?rs:Command=Get&amp;rc:GetImage=8.00.1038.00Report.js">

</script><script language="javascript" type="text/javascript">

<!--

function OnLoadReport()

{

var pageHits = null;

var rep = new Report(1, 16, pageHits, false, docMapIds); <-where error is occuring.

if (parent != self) parent.OnLoadReport(rep);

}

//-->

</script>





It did show the report, but I don't understand why it is still getting an error here. Moreover, I didn't even get the HTMLViewer too even when I had assigned the devinfo....



Really need some help here, as this is quite urgent.... I am at a loss at this, and maybe that there is an option that I am not seeing or something I am missing. please help .
