Urgent: New version breaks binding to Generic Lists, please help

This example does not work in the new version released today : http://www.telerik.com/help/reporting/buildingdatatbindlistcomplex.html

Unfortunately, I have a project going live in a week that has all the reports developed in this way which are now all broken. The chart always shows up as 'no or empty series'

Can someone help?

Report height that uses parameters in report viewer is wrong

When we have parameters for a report, in IE 8 (normal and compatibility mode) the report viewer overflows at the bottom the equal amount of height taken up by the parameters at the top. The parameters do not even display in Firefox.

We are using Telerik Reporting version 2.8.8.723 (Q2 2008).

We have a very small working c# application that can show this behavior.

PDF Profiling - DrawString

Hi there.

I was just doing some profiling on how long it takes to create a PDF report I have created. The resultant PDF file is about 8 pages and has a faily simple table in a group, so the table is repeated for each group.

It took about 10 seconds to generate the report, but about 40% of the total execution time was associated with 582 calls to Telerik.Reporting.Pdf.Rendering.PdfRenderer.DrawString(String, PdfFont, Brush, RectangleF, Boolean).

So, it appears that this method is associated with turning strings into pdf graphic elements. Are their things I can change in my report definition that limit how much this is called by eliminating fonts etc. Are certain fonts less expensive than others? Just curious why drawing characters takes 40% of the execution time.

Thoughts?

Note: I am using the Q1 2010 release.

Mike

2010 Q1 issue

Hi,

I just upgraded to the Q1 release and have an issue with an InvalidCastException issue. I've looked and couldn't find a breaking changes sheet for this ver so am suprised to get an error (this was working with old 2009 Q3 ver).

For the following code I get a message saying "Unable to cast object of type '<EnumRawData>d___0' to type 'System.Data.DataRow'".

    
            Private Sub locationIDGroupHeader_ItemDataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles locationIDGroupHeader.ItemDataBound  
        
                Dim section As Telerik.Reporting.Processing.GroupSection = DirectCast(sender, Telerik.Reporting.Processing.GroupSection)  
        
                Dim row As System.Data.DataRow = DirectCast(section.DataObject.RawData, System.Data.DataRow)

The error appears on the second line...

Any workarounds?

Regards,

Jon

How to Bind Data in Line Chart to Dataset..

I want to bind the series and series items to the dataset (created through Report Wizard). I used the code to bind the data to the datasource given in documentation but it's not helping. Is there any other way to bind the data through series properties or through code in event _NeedDataSoure? The connection, i made is through ODBC.

PDF Export Page Size

Hi,

I have created a master report with many subreports. When I preview the individual reports, they fit on a single page(A4 Potrait/Landscape). However, when I preview the master report(with all the subreports), I see the individual reports overflow to second page(the rows, not the columns). I do have the "Keep Together" property set to "True". What am I missing here? Just to check, when I set that property to False, I see an additional empty page being added in between the first two pages. How can I stop this overflow?

Thanks for any help.
