Hello, i have some panes with summer theme and the pane header looks
nice with a grey gradient brush. When i float any pane to a another position the paneheader
changes the header color to a solid grey background. How can i have the same gradient header
backcolor before floating? thank you for help ... greetings ... ricc

I just updated to the latest version of WPF controls from RadControls_for_WPF40_2011_2_0920_Dev_hotfix.zip and decided to try out the PropertyGrid. I'm not planning on using the autogenerate feature, but thought it might be helpful to point out what I noticed.

Each time I change objects in the Item property, my application becomes unresponsive for a few seconds, and memory usage goes up by anywhere from 20 MB to 200 MB. It never runs out of memory, because it appears in ProcessExplorer to be reclaimed as soon as it hits the memory ceiling. When it is finished, it displays the 30 to 50 properties on my objects. But it does not provide any expanders to view properties of nested objects. (EDIT: I just noticed the NestedPropertiesVisibility setting)

It appears that most of the time is spent in Type.GetProperties() after about ten recursive calls to GenerateNestedPropertyDefinitions(). You might benefit from using some caching so that you don't have to make so many calls to Type.GetProperties(). Maybe something like the TypeInfoCache from http://www.codeproject.com/KB/cs/generaldynamicobjectproxy.aspx. And maybe find a way to perform the property searches on a background thread.

I'm trying to execute the example here: http://www.telerik.com/help/wpf/raddatafilter-how-to-create-custom-filter-editors.html

When I'm inside the EditorCreated triggered method, switching through the property names I try to set the value of e.Editor to a RadComboBox. See below.


I get an InvalidCastException when I try to cast e.Editor. It is of type StringFIlterEditor. What am I missing from the example?

I am trying to display the MaterialName values in the Legend...

The Chart controls creates a line for each MaterialName in the list but I cannot get the Legend to display those names...

All the examples I found use static Legend captions.

I am using this ItemSource:


This is the XAML code:

Hi there,

I am just placing this control on my WPF page, following all instructions and demos from telerik website and I am stuck with "Ambiguous match found " - that does not make any sense to me. Does anyone have any ideas how to solve this problem? Thanks.

Hi -
When will the 2011 Q3 controls be officially released? We're aware that the 2011 Q3 controls are currently in Beta. We'd like to know the date they will be officially released. We want to include them in a new project release, but need to know the exact release date in our to schedule our development and deployment dates.
Thanks,
Sandy

I have a line chart set to display datetime for X-Axis to display DefaultLabelFormat="#VAL{hh:mm:ss}" If the radchart is directly set in the xaml it works fine. However if it is in a datatemplate and rendered through a contentpresenter, it won;t work. even the title and legend won't show up neither. It always display the full date string which getting overlap. See the upper chart. ( In my case I have to put it into a template as that is part of the content in an itemscontrol, I had a hard time to find out that the template gets into the way.) Anybody run into similar issue? what is the solution?

Hi,

I am currently evaluating the Q2 Release for WPF and Silverlight.

The Silverlight Version contains the "RadEditor" Controls. I like the use the RadEdit in a WPF Application.

I referenced the Telerik.Windows.Controls.Editor assembly and here the problems start, the assembly seem to be reference an old version of Telerik.Window.Controls (Version 2009.1.424.1020). The Current Version is 2009.2.701.35.

Is there a way of using the RadEditor within an WPF Application, or is this currently not supported?
