Hi, we are working around this Telerik Reporting known limitation...
"Limited rich text/html content formatting options in the textbox item (only text formatting is available)"

...by converting the HTML generated by RadEditor into an image, then placing this image into a PictureBox control of the Telerik report.

This works OK for us except we have noticed that if the image is > 16384 pixels in height, then the Telerik online viewer shows a 1 pixel high image in place of the actual image, but appears to reserve enough blank space for the actual sized image.

Is this some kind of limitation in the PictureBox control? BTW if we export to PDF the image is rendered just fine.

Nested object with table inside table inside table

My problem:
It seems like i can have table inside table upto 2 layer and my third nested table only prints the first data of my nested collection.

I found help where List inside list inside list..... but I am looking for table inside table inside for my nested object data.
http://www.telerik.com/community/forums/reporting/telerik-reporting/list-in-list-in-list-etc.aspx

So, i have my object set like this (see attached .png):
My Data class contains:
        List<SampleModel>
        {
                new SampleModel
                {
                       contain List<SampleSubItem>
           {
               contain List<Sample2SubItem>
               {
                    contain List<Sample3SubItem>
                }
                    }
            }
      }
}

If you see the attached "report2.png", it shows the preview of my report..
My first table (white color) is good
Its nested table and object SubItem (orange color) is good
its nested table and object Sub2Item (green color) looks good but the data is incorrect. They are all showing first index of the list, that is, Sub2Item 1
its nested table and object Sub3Item should error.

Any help would be great or Is subreport the only fix?

Thank

HTML and PDF versions not the same

I've been struggling to figure out why the first 2 sections of my report are blank on-screen. I can't find any reason for it.

I exported the report to PDF to show it to a coworker, and discovered that the PDF version is rendering exactly as it should! (I also just now discovered that the Preview tab in the designer works OK, but the Html Preview does not)

Can anyone give me any ideas about what to change to make them both the same? What commands are processed differently in the HTML and PDF renderers?

<edit>
I've just realized that the first sections are not missing - the problem is the details section is starting on page 2 instead of page 1. Page 1 has only the report header, page header, and page footer in the HTML version.

(it's a web app using Visual Studio 2008, Telerik Reporting Q3 2009, and C# - in case any of that matters)

Crosstab Report OutOfMemoryException

Conditional totals

Hi all,

In my group footer(s) I am displaying averages (using Avg). However, I need these averages to exclude any zero and null values in the detail lines. How do I go about doing that?

Adding reports to a reportbook

Hello all.

I am trying to setup a report book (programmatically) to load in three reports into a web viewer. Each report is one page of a large 3 page report that I am trying to duplicate here. I had to break it up because each page had different page setting (mainly the orientation). Now I am hoping to read a table and print all three reports for each record of the table (thus producing a three page report for each record). At some point I will pass an ID variable to each report for every record.

I started out with the following code but get an error that the reports are not declared (the OFC21, OCF21b, and OFC21c reports).

        Dim reportBook As New ReportBook()
        reportBook.Reports.Add(OFC21)
        reportBook.Reports.Add(OFC21b)
        reportBook.Reports.Add(OFC21c)

Then I tried to create the report object first and then pass it to the report book but I get the same error when I try to declare the reports.

        Dim reportBook As New ReportBook()
        Dim rOFC21 As New OCF21()
        Dim rOFC21b As New OCF21b
        Dim rOFC21c As New OCF21c

        reportBook.Reports.Add(rOFC21)
        reportBook.Reports.Add(rOFC21b)
        reportBook.Reports.Add(rOFC21c)

At this point I have no idea why it is having an issue reading the reports. The reports were created in a class library project and the dll was brought into this one.

Funny thing is, if I drop a report book control on the page and try and add the reports through there, it sees the reports without and issues.

Any help would be much appreciated.

Paul.

PDF with bookmark

Is there a way to initially display the document map when exporting to PDF.
I saw in the documentation that the report viewer has a property "DocumentMapVisible" that set this. I'm not using a report viewer, I export to PDF. When the pdf opens the document map is not initially displayed.

Labels Report # Per Page

Using the multi-column feature, I have created a labels report that displays 30 labels per page (3 across 10 down). However, after 11 pages, the report starts displaying only 29 labels 10 in the first column, 10 in the second and 9 in the third. From then on, it displays 29 per page for the rest of the report. It does this for both PDF and RTF formats and if I print it directly from the report viewer. There does not appear to be anything different about the addresses on page 12 so I am not sure why this would be happening. Any suggestions?

thanks!

Unknown server tag 'telerik:ReportViewer'.

I'm getting the following error in all Telerik reports in a .NET 4.0 web app I have recently taken over from somebody else who has resigned. Thus far I've had success by installing required MSI files and removed hard-coded versions in web.config files and adding references to the DLL files. But this approach hasn't worked for Telerik ReportViewer. Am I missing something? I've installed Reporting Q3 2010 and added references to Telerik.Reporting.dll and Telerik.ReportViewer.WebForms.dll and also ticked quite a few related namespaces below these references in the properties for the solution, but am getting nowhere. I have never used Telerik before but like what I see so far, apart from these errors :-(

Here's the error (and thanks):

Server Error in '/' Application.

Detection of first- and last row of each rendered page

I am using Reporting Q2 2010. In this release, is it possible to detect which rows of a table are rendered as the first row and the last row of each rendered page of a rendered report?
So, e.g., if I have a table of five rows of which the first three rows are rendered on the first page of the rendered report and the last two rows are rendered on the second page of the rendered report - then is it possible to detect that the first and fourth row are rendered as the first row and the third row is rendered as the last row on their respective rendered pages?
