Overriding Control Template in a Custom Control Library not working

I have the following derivation that includes the customary static constructor.

public class CustomRadDatePicker : RadDatePicker

static CustomRadDatePicker()

{

DefaultStyleKeyProperty.OverrideMetadata(

typeof(CustomRadDatePicker),

new FrameworkPropertyMetadata(typeof(CustomRadDatePicker))); // also tried RadDatePicker here

}

In the XAML for the controls template I have the following.

<Style TargetType="{x:Type SharedControls:CustomRadDatePicker}">
...

<Setter.Value>

<ControlTemplate TargetType="{x:Type SharedControls:CustomRadDatePicker}">

Now when I use the control on a page it does not use the style I have set up but is using the Telerik style.
I have my derived control and its template set up in a WPF custom control library.
Is it allowed to override the Teleric Style?

Moving the close button to the tab header.

So instead of having a one close button at the far right of the tab strip, you'd then have a close button on each tab header (like the tabstrip on Google Chrome).

Possible?

Draw annotations on top

I am pleased to see that Telerik has implemented the ability to draw custom lines onto the chart, after the request (http://www.telerik.com/community/forums/wpf/chart/drawing-extra-elements-into-or-on-top-of-chart.aspx) that was made; although I don't know if it was already in the works.

Is it possible to draw the CustomLines on top of the Bars? If the Bar's item width percent is set to 100 they effectively are invisible unless drawn at a Y-Value above the bars.

Changes to ObservableCollection not reflected in Grid

I have a fairly simple scenario. A non-hierarchical grid bound to an ObservableCollection<T>. The collection resides on a ViewModel. When I load the view, the grid displays data appropriately. A seperate control on the page can force a refresh of data in the ObservableCollection. That is, the collection is cleared and repopulated with new items based on the outside criteria. When the operation completes, I see a new count in the collection, but the rendered grid is unchanged. It was my understanding that the grid would respond to events raised by an ObservableCollection and that no additional handling was necessary. I'm aware of a Rebind method on the grid, which I could call to force a rebind, but as you may be aware, knowledge of controls in a ViewModel is not appropriate.

Any ideas why the grid would not respond to changes in the collection? Also, if I must force this rebind using the Rebind method, what are some strategies to initiate this from the ViewModel without calling the grid directly from the ViewModel?

Thanks...

problem when changing Appearance colors

Hello,

I'm currently building an application where the user has some control on how a chart looks.

Every property I'm changing work perfectly except for anything linked to a brush.

The different brushes the the SeriesAppearanceSettings are correctly updated till a Rebind() is called or till the ItemSource is changed when a color change has been previously called. From that point on an ArgumentException is thrown if I attempt to change a previously changed brush:
"The provided DependencyObject is not a context for this Freezable.
Parameter name: context"

here is my method for changing colors:

public void SetFillBrush(Brush color)

{

_lineDefinition1.Appearance.Stroke = color;

_barDefinition1.Appearance.Fill = color;

_areaDefinition1.Appearance.Fill = color;

_lineDefinition2.Appearance.Stroke = color;

_barDefinition2.Appearance.Fill = color;

_areaDefinition2.Appearance.Fill = color;

}

Any help is appreciated.

Theming controls with a Style in Blend

I'm trying to set a global theme for either Telerik controls or non-telerik controls in xaml using a style. This works in Visual Studio, but not in Blend. I get the error: 'Office_Blue' is not a valid value for the 'Telerik:Windows.Controls.StyleManager.Theme' property on a Setter.

I am using RadControls for WPF Q1 2010 SP2 (version 2010.1.0603) on Windows 7 x64. Here is the xaml:

<Style TargetType="telerik:RadGridView">

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

</Style>
