Hi,

using c# .NET 4.5, Wpf, RadTabControl (DataContext is a TabViemodel).

I bound a VieModel on my RadTabControl. With a Command on a RadButton, i add a new TAbItem and load a UserControl
as Contet.

On initializing the USerControl i try to access the ViewModel from the TAbControl, but without any success. As you can see on
the attached File the SelectedContent is my VieModel, but the var yyy is null?

Thanks
Best Regards
Rene

Environment: WPF,MVVM, Odata 2, EF6, MVC

Scenario: 

Attempting to submit a master/detail payload as a single transaction via a Telerik QueryableDataServiceCollectionView. Payload consists of 1 master record and 12 related detail records for insert.  

I have included the following code in WebApiConfig:

config.Routes.MapHttpBatchRoute(
        routeName: "WebApiBatch",
        routeTemplate: "api/$batch",
        batchHandler: new DefaultHttpBatchHandler(GlobalConfiguration.DefaultServer));

 and 

 config.Routes.MapODataRoute(
"odata",
"odata",
builder.GetEdmModel(),
batchHandler: new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));

Now on the Client side, I don't know how to tell the QueryableDataServiceCollectionView to transmit the payload as a single transaction when SubmitChanges() is called.

ViewModel Constructor:

this.odataScoreService = odataScoreService;
odataScoreService.Service.SaveChangesDefaultOptions = SaveChangesOptions.Batch;

ProjectPhaseScores = new QueryableDataServiceCollectionView<ProjectPhaseScore>(odataScoreService.Service, odataScoreService.Entity);
ProjectPhaseScores.Expand = "ScoreItems";
ProjectPhaseScores.LoadedData += OnLoadedScoreData;
ProjectPhaseScores.FilterDescriptors.Add(projectPhaseFilterDescriptor);


I am still very new to Visual Studio Development so any assistance would be greatly appreciated.

How to read content from RadRichTextBox in codebehind

Thanks
Bindu

I've just started working with Telerik UI for WPF and have been working with implicit styles. I got the implicit styles working but haven't been able to access the theme variations as detailed in the documentation. I inserted the variation code into my code-behind file as shown below:

 public partial class MainWindow : Window
    {
        public MainWindow()
        {
            //dark color variation
            VisualStudio2013Palette.LoadPreset(VisualStudio2013Palette.ColorVariation.Dark);
            InitializeComponent();
        }
    }

But get the following error message:

Error 1 The name 'VisualStudio2013Palette' does not exist in the current context 

Any ideas?

Hi,

I get an error when I try to remove a tab item containing a RadAutoCompleteBox regardless of the content of the box -even if it's empty- it still gives an error. It breaks with an "Object is not set to an instance of an object" error trying to load RadAutoCompleteBox .cs at line 1326 0x30 bytes.

Thanks in advance.

For a customer project we are working with the radscheduleview (Q2 2014).

We are using specialslots to display slots with different task type. These slots can have a recurrence pattern which is supported by the Slot class.
We are able to display slots which occur daily every second day for example.

Where we run into problems is when we want to start using exceptions on the recurrencepattern. For example recurrence should be removed on a specific date.
For appointments the recurrencerule is used to add/delete exceptions of the recurrencepattern. We would like to be able to do the same for specialslots and are actually supprised that this is not a feature that is supported by the Slot class.

Is it currently possible possible to add exceptions to Slots or would it be possible too add such a feature?
