RadTabItem HeaderTemplate not responding to binding to UserControl object properties

I am using the RadTabControl to host UserControls within its tabs. Its ItemsSource property is set to an ObservableCollection<UserControl>. So, to properly name these tabs I had planned to create a HeaderTemplate and simply bind to the Name property of my UserControl, converting it to a user friendly string of course. To do this I used the following:

TabControl declaration:

<telerik:RadTabControl x:Name="radtabVariableControlsContainer" Margin="0" d:LayoutOverrides="GridBox" Grid.Column="1" BorderBrush="{x:Null}" ItemsSource="{Binding MainContentControls}" SelectedItemRemoveBehaviour="SelectPrevious" ItemContainerStyle="{StaticResource MainContentItemContainerStyle}"/>

ItemCotainerStyle:

<Style x:Key="MainContentItemContainerStyle" TargetType="{x:Type telerik:RadTabItem}">

<Setter Property="HeaderTemplate" Value="{StaticResource ContentAreaTabHeaderTemplate}"/>

</Style>

Finally, the HeaderTemplate:

<DataTemplate x:Key="ContentAreaTabHeaderTemplate">

<TextBlock Text="{Binding Name, Converter={StaticResource TabHeaderTextConverter}}" FontFamily="Arial" FontSize="13.333"/>

</DataTemplate>

With this setup, nothing shows up for the header text. The converter is not the issue because removing it does not solve the problem. It seems to be that the Binding cannot execute at Runtime because when editing the template in Blend, the Binding works and shows the correct value. Also, putting any clear text in for the textblock's text property works.

Style problem

Hi!

I have some problem with applying a style on a custom control derived from RadTreeListView.
This is the base style that works correctly on original RadTreeListView:

<Style TargetType="{x:Type telerik:RadTreeListView}" x:Key="IprRadTreeListViewStyle" BasedOn="{StaticResource IPRBaseStyle}">

<Setter Property="ValidatesOnDataErrors" Value="None"/>

<Setter Property="telerik:StyleManager.Theme" Value="Summer"/>

</Style>

I create another style based on the previous style:

<Style TargetType="{x:Type controls:IPRRadTreeListView}" BasedOn="{StaticResource IprRadTreeListViewStyle}">

</Style>

The CS code of my custom control:

class IPRRadTreeListView : RadTreeListView

{

static IPRRadTreeListView()

{

DefaultStyleKeyProperty.OverrideMetadata(typeof(IPRRadTreeListView), new FrameworkPropertyMetadata(typeof(RadTreeListView)));

}

public IPRRadTreeListView() : base()

{

...

}

...

}

If I run the application then my IPRRadTreeListView control doesn't become visible. I tried to apply the style explicitly ( Style = {StaticResource IprRadTreeListViewStyle} ) on my control but I had the same result: IPRRadTreeListView wasn't visible.

This scenario works correctly for IPRRadGridView (derived from RadGridView).

Could anbody help me, please?

Problem with BussyIndicator...

Hallo,
we have a serious problem with BussyIndicator component with the combination of theme "Metro". We're using bussy indicator inside splash window, which is opened during the app start up in the separate thread. Folowing exception is raised:

----------- Exception

{

(this._splash as IDisposable).Dispose();

}

#region helper class SPlashStartInfo...

}

public string SplashTitle { get; set; }

public string SplashText { get; set; }

public string VersionInfo { get; set; }

public IntPtr OwnerHandle { get; set; }

}

If I set in the App.OnStartup() method "StyleManager.ApplicationTheme = new MetroTheme();" the exception is raised, when I use any other theme, application starts without any problems.. Thanks for any solution.
Tomas.

QuickAccessToolbar Below the ribbon

If you move the quick access bar below the ribbon the text "Show below the ribbon." becomes blank.
It also happens in each of your WPF demo ribbonview applications.
At least it does on my machine (windows 7 32bit).

Attached is an image of it happening in your demo.

Please let me know if there is a patch or a way I can override it in code-behind c#.

DataFilter Style

Hello, I've tried to generate the style for the control as said onhttp://www.telerik.com/help/wpf/raddatafilter-styles-and-templates-styling-the-raddatafilter.html

But, I can't seem to do the "Create a Copy" for creating the style/template structure for the control.

Where can I find it to be able to put on my ResourceDictionary and edit the Style default?

Thanks
