Hi

I have created my own WCF service which uses the ReportProcessor to render an Xps to be used in the WPF DocumentViewer control. It worked fine when using the ReportProcessor directly from the App. But at soon as I move it to a service it fails.

I have created unit test that proves that the ReportProcessor works fine.

I get the following exception:
Test method Dako.ReportingService.UnitTest.DakoReportServiceTest.TestRenderXpsWithServiceHost threw exception:  System.ServiceModel.FaultException: FixedDocument must contain at least one FixedPage..

And when I look at the Debug trace I see another error:

I have another test that also calls the service which passes.

What am I doint wrong?

When I export my report to Excel, how can I get the columns to 'Autofit'?

In my report, I want to change the value of a textbox based on the value of the row data. I can't really use an expression because I may need to do a additional data lookup (depending on the data). Instead, I use the detail_ItemDataBound method to process the row data and change the text. At the same time (using the same method) I also change the visibility of another text box.

When I run the report, the visibility works fine, but the text is only changed on the row after the one being processed (the text for row n is displayed on row n+1). 

Is detail_ItemdataBound the right place to do this processing? Would detail_ItemDataBinding be better?

When do I use each one?

TIA.

I have a master report that uses a single group. Within each group, I display a subreport with data for the group. When the report is displayed using the ReportViewer control on my web page, the first sub-report is empty, and the second sub-report contains the data for first group etc.

I step through the code in the debugger to be sure the correct data is being supplied for the group data, and it appears to be correct.

Are there any known problems with using grouping and sub-reports? Are there any other mistakes on my part that could cause this behaviour?

It's happeneing on two separate master/sub-report pairs, and it's very repeatable.

TIA.

Hi,

I have a created a simple report in Silverlight but when I run the application I get this error:

AG_E_UNKNOWN_ERROR:

System.Windows.Markup.XamlParseException occurred
  Message="AG_E_UNKNOWN_ERROR [Line: 26 Position: 36]"
  LineNumber=26
  LinePosition=36
  StackTrace:

       at Silverlight_Reporting.MainPage.InitializeComponent()
       at Silverlight_Reporting.MainPage..ctor()
  InnerException:


Here is my code from the MainPage.xaml

<

 

reportViewer:ReportViewer x:Name="xReportViewer"

 

 

    ReportServerUri="../ReportService.svc"

 

 

    Width="1000"

 

 

    Report="ReportLibrary.BasicReport, ReportLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">

 

 

 

 

</reportViewer:ReportViewer>

 

Hello,

I don't see the the ZoomMode and ZoomPercent properties for the Silverlight ReportViewer? Do they exist? Do they have different names? Are there equivalent properties I should be looking at?

Thanks,

Hi,

I created a class library project to create my reports and use that in an existing web application. I created a table adpater which uses an existing stored procedure(with parameters). I am using these reports in my application using the reportviewer. The parameters for the stored procedures are controls on the page containing the reportviewer. I am unable to figure out a way to pass the parameters from this page to the stored procedure and display the correct report. What am I missing?

Thanks

I have a report that binds to a collection of objects. One of the properties on the object is an enumeration. When the report is ran, the field with the enumeration shows up as an integer. How can I convert an enumeration field to use the actual value of the enumeration instead of the integer value?

Hey, this may sound like a stupid question
But is there a way to inject HTML Document in the report, say like IFrame

We've a rendered HTML page that we want to include or capture in the report, is there a way to do so?
i've looked the HTMLTextBox control, but i guess it renders only html text, not complex html page including images and charts :'(
