The sampling and performance of RadChart's ability to show thousands of data points in an intelligent way is great. The biggest problem for me is how to transfer this data from the server to client. In a real world scenario, this data is going to reside in a persistent store like database and a WCF service will help getting it.
All the example's I've seen so far works with random data generation on the client side. How can I efficiently bring such a large volume of data from a WCF service.
I believe the sampling only occurs on the client side after you have bound all the datapoints, series mapping to the chart.
Many Thanks in Advance.

Hi,
I'm not sure if anyone else has run into this. Whenever I use the Docking control my msn messenger gets set to busy. It also happens in the Docking Examples in the RadControls for WPF Demos.
Wondering if you had any ideas on what I could do to get around this?
Thanks Much,
~Boots

Hello!
The RadPane's context menu is useful in many scenarios and I would like to keep this feature in my application, but I need to limit that context menu to appear only when I right-click the header or when I click the small arrow in the upper right corner of the RadPane, because in my case, the RadPane content consist in a WrapPanel having some custom controls that treat their own right-click event ( so I don't want the RadPane to show it's context menu when I right-click inside it )
Is this possible?
Thank you!

The items in my chart legend are arranged horizontally, even when I have the legend on the right. What do I need to do to get them to be arranged vertically? In the demos, this seems to be the default, but for me for some reason that doesn't happen.
Edit: the title is a little misleading; I mean "orientation" rather than alignment, but hopefully the picture and description makes it clear what I mean.

Has anybody else experienced slowness when either sorting a column or resizing the width of a column?
To sort or resize a column it is taking 8 seconds, you might think many rows is the problem. But I would not say that 320 records is a lot of rows.
I'm using the Model View View Model concept and creating a custom class that is binding to the grid. Could this approach be causing the slowness?

Hi
I am currently trialling the Q2 controls and have a couple of questions regarding the RadPanelBar.
Firstly - I have used the ControlTemplates provided in the documentation to re-style the panel bar and the panel items. However the content headers and the items are now styled the same, what I want is for the header to stand out from the items. Could you please advise how I style these two items differently?
Secondly - is there a way to set the panels so that when expaned they only take up the space required for their items? At the moment the panels are expanding to fill all available space - for example I have three sections, when I expand the first section the other two sections are pushed to the bottom of the container, I would like the sections to expand only enough to show their items.
Thanks.

Hey,
I´ve got a problem with styling an PanelBarItem in a HierarchicalDataTemplate.
I copied a style and tried to bind it to my PanelBarItem, but only the default-style appears (with the exception of the foreground, this color agrees with my style ).
Do I have a simple PanelBar with a view items in it and bind the style to it, everything is fine.
Causes the HierarchicalDataTemplate this missing style?
Below the Structure of my PanelBar:
