How do I add a support page to end of the report. Heard something about using the report book, like to see an example on how to do this. As much detail as possible, thanks in advance.

Hi. I have built a DLL that generates a PDF. The problem is that the error message "PDF rendering format is not available" appears, unless the Telerik dlls are referenced in the calling application.
How do I need to proceed?
Here is the code in the Calling Application:
This is the code that is failing in the DLL:
Of course, it fails on the "Render" call.
How do I need to proceed?
Here is the code in the Calling Application:
| byte[] b = conv.GeneratePDF(); |
| FileStream oFile = File.Open("C:\\test.pdf",FileMode.OpenOrCreate,FileAccess.Write,FileShare.None); |
| oFile.Write(b, 0, b.Length); |
| oFile.Close(); |
This is the code that is failing in the DLL:
| public byte[] GeneratePDF(List<FieldDescriptor> fieldList, DataTable dtFields, string reportName) |
| { |
| ReportDataTable = dtFields; |
| FieldList = fieldList; |
| ReportName = reportName; |
| Telerik.Reporting.Report report = GetReport(); |
| string mimeType = string.Empty; |
| string extension = string.Empty; |
| Encoding encoding = null; |
| byte[] buffer = Telerik.Reporting.Processing.ReportProcessor.Render("PDF", report, null, out mimeType, out extension, out encoding); |
| return buffer; |
| } |
Of course, it fails on the "Render" call.

I have a report where I display the data in 2 columns, side by side.
In the group section I said to do a pagebreak when the group item changes.
However, the instead of going to the next page, it goes to the next column.
Therefore I tried to give a page break before and after the group. But it didn't help either.
Any idea on how to fix this bug?
Thanks.

Hi
Is that in any way possible to set the detail section to a specific height and keep it even though there is not enough data in the child list to expand it?
I have a fix layout, where the detail section has to have a background company logo that has to be shown on all pages.
As of now, when the list in the detail section expands to a second page, and takes up only one row, the rest of the detail section on that page is blank, and no logo is shown.
Is there a way to overcome this behaviour? (Please don't say it's design behavior ;) )
Thanks.

When I run my application inside of Visual Studio 2010 the Ajax Report Viewer works beautifully. When I run the same exact code inside of IIS on Windows 7, I get a "503 Service Unavailable" error out of IIS. IIS isn't writing any log entries to any of the logs (event viewer, access logs, failed request trace logs, etc.).
I have the same exact code working on a Windows 2008 Server with no problems.
Is there something special that needs to be done for deploying the Telerik Report Viewer on Windows 7?
Is there any way to find out what is causing the 503 error?

For testing, I have a pie chart with 8 items. The YValue of the item will be set in the NeedDataSource event. Since I am using the Telerik skin, the first item is green, second is yellow, third is red, and so on. I need to have these color consistent since I will be referencing the color elswhere on the report.
Item1 = green
Item2 = yellow
Item3 = red
Item4 = blue
If I add only the items that have non-zero value the color will not be consistent. For example, Item2 is zero then if I add Item1 then Item3:
Item1 = green
Item3 = yellow
Item4 = red
Item5 = blue
I need to make some of the items invisible. However, setting Visible = false does NOT hide the item. Suggestion?
I also tried the Remove() method but I get "An eroor occured while processing Chart... Object reference not set to an instance of an object."
foreach (ChartSeriesItem i in responseSeries.Items){ ... if (i.YValue == 0) { i.Visible = false; } ...}

I successfully bound the datasource of the reportviewer, but the reportviewer itself isn't showing anything up. What am I missing?
I haven been trying to set the design of a Telerik ReportViewer, but not succeeded.
Is there a how-to somewhere, where I can see how to bind the design?
Thanks in advance,
Regards

I have chosen the Mac skin and added a hatch to the Series-->Appearance-->FillStyle. In Fill Settings I have made my MainColor White and left the SecondColor what the skin populated.
In the designer the changes look the way I want and expect however at runtime it reverts back to the skin without hatching.
See the two images for a better idea. I am suspecting the Skin is overiding any changes I am trying to make.
Is there a way to add a hatch to series when you use a skin?
Thanks for any help
