I am running the latest paid for version of Telerik WPF as downloaded today, on an XP workstation with 2 monitors.


1. Launch "C:\Program Files\Telerik\RadControls for WPF Q2 2010 SP1\Demos\Examples.WPF\Telerik.Windows.Examples.exe"
App opens on Primary monitor (in my case, the one on the left).
2. Hover on Browse Controls circle, choose "Containers"
3. Choose "Docking" icon
4. Choose "Split Containers". Screen rearranges with a docking demo
5. Drag and release "Document 1" out of the main window, but still on the same monitor.
6. Press "Windows Key + L" to lock Windows
7. Type in your username and password to unlock Windows
Notice now that the "Document 1" window is now on Right Monitor.
Main window is still in original position on Left Monitor
8. Try to drag "Document 1" to the Main Window - don't let go of mouse button (i.e. keep dragging)
- as the mouse moves onto Monitor 1, the "Document 1" window is not drawn on Left Monitor, only on Right Monitor
- compass on Main Window does not appear
- moving the mouse back onto Monitor 2 still has the "Document 1" window

Other behaviour:

Dragging the main window onto the right monitor, you can then redock "Document 1" into it.
With the main app on the left monitor, Dragging any of the other panels out of the app onto the right monitor and then (without letting go) back onto the left monitor - the controls do not render on the left screen.

Thanks,

Hi,

I have to style our app and for that I need to change some values in the ButtonChromeStyle.
To check my changes I would like to have a documentation of the ButtonChromeStyle. I need to know when which Borders and Triggers are activated, e.g. what has the user to do in the gui to see the styles:
"PressedVisual"
"ActiveVisual"

<MultiTrigger.Conditions>
    <Condition Property="RenderEnabled" Value="True"/>
    <Condition Property="RenderPressed" Value="True"/>
</MultiTrigger.Conditions>

I hope you can understand my problems.

Thanks and regards,
Patrick

Hello All,

I am placing multiple push pins all over the state based on addresses.  The push pins are placed correctly and I can see them, however, I cannot figure out how to zoom the map in to it's highest zoom level but still keep all of the push pins visible.

Has anyone done this yet?

Thanks in advance...

Hi,

I've created a new type column by inheriting from GridViewBoundColumnBase and it's using a StyleSelector.

Is there a way to force a cell to call it's style selector for refresh it's style base on some external (from the grid) action ?

I need to change the color of the cell even if it's content hasn't changed at all.

I'm using a QueryableCollectionview as datasource for my gridview.
Filtering, sorting and grouping are set by using the Group-, Sort- and FilterDescriptors properties.

Now I'm trying to use the deferred scrolling of the grid, but the ScrollPositionIndicator is only shown for the groups, 
meaning no ScrollPositionIndicator for each item in that group.
Setting a ScrollPositionIndicatorTemplate from xaml doens't solve this behavior.

Clearing the Group-, Sort- and FilterDescriptors properties from the QueryableCollectionview solves the problem, but that's no option.

Any ideas or suggestions on this? (Telerik controls version 2011 Q1)

Hi,

I started using the RichTextBox component in our WPF Application and I found an issue regarding the version of the System.ComponentModel.Composition.dll which is being used by the control.

If I use the one that comes inside the Q1 2011 binaries package(version 2009.7.8), the control works fine. The problem is that I'm already using the same dll provided by .NET Framework 4.0(version 4.0.30319.1) in my project which produces a crash regarding wrong dll version when the control tries to load.

Which is the reason why the control is using this "personalized" dll? I see that the size of both dll is different too so I assume that the one that comes with the controls has some modifications. Do I have any workaround to deal with this issue??

Hope you can help me with this problem.

Thanks and Regards,

Carles

In case you are targeting .NET 3.5 you will need to install ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows 7 and Windows Server 2008 R2 or ADO.NET Data Services Update for .NET Framework 3.5 SP1 for Windows 2000, Windows Server 2003, Windows XP, Windows Vista and Windows Server 2008 depending on your operating system.

Staying committed to our plan to further improve the ease-of-use and provide new controls and major features for achieving Rich Data Visualizations and Line-of-Business applications, we are proud to announce the Q2 2011 Beta release.

New Executive Dashboard demo

 

Telerik’s Executive Dashboard demo showcases the next generation of rich data visualization achieved with RadControls for Silverlight. Theming, real-time customization, and a dashboard structure that follows the industry’s best practices ensure that data is displayed in a meaningful and engaging manner. 

New controls and major features

Persistence Framework 

You can now save and load the state of the user interface so that the end user can continue working with the application as it was before closing it. 

• Built-in integration with isolated storage for saving and loading the data 
• Rich and flexible settings to control the serialization process 
• Customizable serialization and deserialization 

DataServiceDataSource 

The DataServiceDataSource control ensures seamless integration between Telerik data controls and WCF Data Services. Binding to the DataServiceDataSource is straightforward and absolutely codeless. Thanks to this new control your applications will achieve maximum responsiveness as data operations will be asynchronously executed on the server.
 
PropertyGrid
With this new control you can easily display and edit properties of an object at runtime. The PropertyGrid provides an easy and versatile approach to processing data-objects' properties. Utilizing its auto-generation features and the intuitive custom editors’ capabilities, users will be able to either display data in a way that best fits their needs, or modify it with minimal effort. 

 

Breadcrumb (only available as part of RadControls for Silverlight at this time. For the official Q2 2011 release the control will also be available for WPF).

Build complicated navigation systems through hierarchical data with many levels. With its powerful data-binding mechanism, the control lets you display hierarchical structures, such as directories and relational data. 

 

RibbonView 
The new RibbonView control now provides significantly improved XAML, MVVM, Blend and Design-time support. We had to take the decision to introduce this new control as the existing RibbonBar control did not allow us to implement the architectural changes to achieve the desired results. As always we will stay committed to assist our customers in moving to the new RibbonView control. For that purpose we will continue to support (minor bugfixes) the old RibbonBar control towards the end of the year. 

ImageEditor 

Add image editing capabilities to your applications with basic operations like crop, flip, resize, and rotate, as well as the ability to use custom pixel shaders. 



RichTextBox

• Headers and Footers support - you can now define headers and footers in the RichTextBox document area, set different headers and footers on odd and even pages as well as custom headers and footers on the first page of your documents
• Input Method Editor (IME) - the RichTextBox now supports writing in languages that require Input Method Editors 
• Support for image blocks - now images can be added to the document not only inline, but also as floating blocks with the text wrap around the images 

Data Visualization

• Now you can inverse the range of the Chart axes
• The Map control supports SQL geospatial data and Bing Traffic provider
• TimeBar now offers Minutes and Second interval types as well as localization support
