WPF can display very complex text, like mathematical function, or create intricate image.
Such feature is missing in Reporting.
A function should exist in Reporting to render a WPF control as image in report for such case (using RenderTargetBitmap).

The Reporting Graph item support now only one data source, unlike RadChartView.
When displaying different collection, we must for the moment put everything in one collection, and group/filter in Graph, because of this limitation.

The expression language leaves much to desire, especially when working with object models. The most irritating is the iif function that evaluates all expressions, that forces to write user functions every time a method on an optional object should be called.
Ideally the scripting/expression engine is based on c# and/or vb compiler.

I would like to be able to write an expression that will call a user function when the ItemDataBound event fires for the report.  This would allow me to wire up the custom functionality that we have built so that the user can see the result from the preview in the designer.  Currently the user has to go to a preview window in our application to see the result but if I had a way to wire the ItemDataBound event for the report then I could make it possible to see the result without leaving the designer.  

I thought that if you made this possible for the report it probably would make sense to enable it for all controls since they all have the the ItemDataBinding and ItemDataBound events.  In my case I don't know how I could implement this any other way because it needs to run after the binding has completed for the entire report.

Telerik Reporting Online Examples have lots of examples of reports, but no examples of how to call these reports!   I'd like to see examples of calling a report from a button on a page, or calling a report by clicking on a button in a radgrid row, and of course passing parameters from said pages or grids.

Hi Telerik!
I spent lots of time investigating the following situation.
For some reason the editor that I used to modify Telerik.ReportDesigner.exe.config file switched xml elements names to lowercase.
ReportDesigner was not started at all in that case. Even no error message was shown.
I had to explore system events logs and found that ReportDesigner.exe throwed an System.IO.FileLoadException.
But still with no details.
Only after hours of exploring I found the problem with xml-element names and fixed it.
I think if you add .config file validation with user-friendly messages during ReportDesigner starting it will help.

We have developed additional logic around the Telerik Reporting Engine so I don't know if this would be valuable to anyone else or not but I would love to have the ability to associate custom properties to a control.  

The use case that comes to mind most is the logic we have implemented to auto size text that displays on a report to fit in the area provided.  We use a control naming scheme to determine what controls should be auto sized and how they should be sized in relation to other parts of the report.  It is typically assigned used with a Panel, a TextBox, or an HTMLTextBox.

I would love to have the ability to add two associate two additional properties to these controls that could be used in the stand alone designer to allow users to set an AutoSize (true / false) and a SizingGroup (string) property on these controls rather than worry about making sure the control is named properly.  I would allow users to more easily leverage this functionality.

I realize that it is unlikely that this will be implemented since it wouldn't be widely used but I like to dream.

I want to download patch Q3_2012_SP1_v6_2_13_110 for reporting but unable to get it. I unable to find the link. could you provide link for this?

Running the report book demo in Chrome v "34.0.1847.116 m" under Windows 8 crashes the Silverlight plugin. This does however not happen under I.E 11.
