I write WPF MVVM Prism 6 application and try to use RadPropertyGrid. How can I initiate (raise) BeginningEdit event without of using of RadPropertyGrid.BeginEdit method? I cant call BeginEdit method because my application is pure MVVM one and I don't use codebehind. If I simply change the value of the property by typing the value of selected property then BeginningEdit event is not raised. Is there a way to initiate BeginningEdit event in MVVM application without call of BeginEdit method?

I am trying to follow the instructions from: http://docs.telerik.com/devtools/wpf/styling-and-appearance/styling-apperance-implicit-styles-overview.html#applying-theme-globally-in-your-application From the picture below you can see that it definitely is in my list of References. I apologize if this is a stupid question as I am fairly new to WPF (WinForms was my thing).

I included a Theme's Folder and put the XAML files into that. I am able to reference them with out error but it does not seem to want to apply the theme to my button type:
<ResourceDictionary Source="/Themes/System.Windows.xaml"/>
<ResourceDictionary Source="/Themes/Telerik.Windows.Controls.xaml"/>
As you can see in the picture I have tried using the dll files as references but it doesn't they they are referenced.
<ResourceDictionary Source="/Telerik.Windows.Themes.Green;component/Themes/System.Windows.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Green;component/Themes/Telerik.Windows.Controls.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Green;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Green;component/Themes/Telerik.Windows.Controls.Docking.xaml"/>
Anyone able to tell me why it is not able to use the Theme Green dll Reference?

Hi,
I have a PolarChart with multiple series. The problem is that the scale of the two series is entirely different and when I plot them I am unable to see the one with smaller values.
Is there a way in RadPolarChart similar to RadCartesianChart where I can specify a different axis to plot the second series and also a different location for the secondary axis.
Thank You

In our project, we have a requirement to show, millions of data from databas and hence we have used
Data virtualization feature in RadGridView using VirtualQueryableCollectionView. Now loading is working
as expected, but we have add/edit/delete functionality within grid. But that seems not working.
Could you please provide some sample or document which can guide us to achieve this.
Looking forward to hear you soon.

Hello,
the Office2013 theme corrects the text of the header so that they are in uppercase.
This work correctly when we just set the header as a text, but not if we want to customize it, for example to add an image or something else. It seems that the theme takes the Text property of the header content, converts it to uppercase and use the result to display in the header. If the header content doesn't contain a Text property, nothing is displayed.
To see this in action, just create a WPF application, add the relevent assemblies and replace MainWindow.xaml with:
If you run the application, you will see that the first header is displayed, but not the second one...
In all other themes I tested, including Windows8, both headers are displayed.
To correct the problem, I think that the best solution is to check whether the header has a Text proprty. If there is none, you should display the header as defined by the user, without changing it.

Hello, I am getting the following exception when using grouping in RadGridView. The problem is that the exception seems to happen not inside my code,
but entirely inside Telerik RadGridView control, so I cannot catch the exception. Any tips how to catch this exception or better - avoid the exception from occuring? I using the Telerik version 2016.1.217.40. My twitter handle is @Tore_Aurstad. Nice if you got any tips, we are closing in on our release date for our client which is using the Telerik WPF library heavily.
Thanks,
