Chart Series Opacity read only

We have noticed with your chart control that when we set it so that the point labels are showing it makes the opacity of the series definition read only. Is there a way to disable this behavior or work around it so that we can change the opacity in this case? Currently we turn the opacity to 50% for all other series when the user hover’s the mouse over one of the series items in the legend. If the point labels are on and the opacity locked we are unable to do this. Any help on this matter would be greatly appreciated.

Thanks in advance

RadCarousel not showing items correctly

Hi.
I'm using the RadCarousel Control.
I have a List<BitmapImage> and when I add a BitmapImage to this list, I add a Image, with the BitmapImage as source to the RadCarousel.Items

But, instead of showing the actual image. It's showing a dot.

I've tryed to attach a sample project that reproduces my problem but I couldn't.
So follows my code:

XAML:

    
            <Window x:Class="radcarouseltest.MainWindow" 
        
                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                    Title="MainWindow" Height="350" Width="525" 
        
                    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"> 
        
                <StackPanel> 
        
                    <telerik:RadCarousel Name="carousel" FlowDirection="LeftToRight" VerticalAlignment="Center"  
        
                                         HorizontalAlignment="Center" HorizontalScrollBarVisibility="Disabled"  /> 
        
                    <Button Content="LoadImages" Click="Button_Click" /> 
        
                </StackPanel> 
        
            </Window>

Windows7 Theme

In the Docking/Compass/Programming of the wpf demos, there is a dropdown list of themes, such as Vista and Windows7.
I was trying to find the Windows7 theme file and customize it, but I couldn't find the theme files. Where are the theme files located?
The source code file doesn't include the code for the theme dropdown button. Where is the source code of the dropdown theme button.

RadWindow: Information dialog

Hi,
I noticed RadWindod has methods to display alerts (RadWindow.Alert) and confirmations (RadWindow.Confirm)
How can I show an Information dialog that has just an OK button and shows the proper Information icon?
Think of messages like "The operation completed fine" or "Your file has been saved"...

Thanks,
Alessandro

How to Compile WPF Examples in VS 2010?

Today I upgraded using

    
            RadControls_for_WPF_2010_1_0422_DEV.msi

I copied the Demos folder to my D: drive so I could make changes without elevated rights. VS2010 did its upgrade but when I built the solution I got 333 errors. To make sure I didn't mess up I carefully copied the Demos to D:\Telerik 2\Demos and tried again. 333 errors the 2nd time too. The errors started similar to the first three VS2008 error in this post, 2nd definitions of _EmployeeID etc. Altova DiffDog confirmed a new file, "Northwind1.designer.cs".

It took me a long time to decide I had not made a mistake. I would prefer to download a VS2010 set of Demos, rather than convert a VS2080 solution.

Grid is not updating Text on modifying the bound observable collection

Hi,

I have a Grid which is bound to an observable collection. The first column is a Combobox. Based on the selection in the first column, I need to change the values of the remaining columns in the same row. I tried to modified the Observable collection but the text of remaining columns are not getting changed. But if I click on each of the remaining columns, text is getting updated. Please help.

Thanks and Regards,
Norbert John
