Binding and Style

[Chris Greening]

Does anyone have an exampe of how to bind any of the Style properties?

I've tried the following but it ignores the style but does pick up the TextBrushStyle and my header is black text on a black background:

XAML
<my:GridViewDataColumn IsGroupable="True" IsFilterable="True" IsReadOnly="True" Header="Reference No." DataMemberBinding="{Binding Path=ReferenceNo}" HeaderCellStyle="{Binding GrdCasesHeaderCellStyle}"

Code
Style _grdCasesHeaderCellStyle;

public Style GrdCasesHeaderCellStyle
{
get { return _grdCasesHeaderCellStyle; }
set 
{
_grdCasesHeaderCellStyle = value;
NotifyPropertyChanged("GrdCasesHeaderCellStyle");
}
}

GrdCasesHeaderCellStyle = Application.Current.Resources["GridViewHeaderCellStyle"] as Style;

Resources
<SolidColorBrush x:Key="TextBrush" Color="{StaticResource BlackColor}" />

<Style x:Key="GridViewHeaderCellStyle" TargetType="Telerik_Windows_Controls_GridView:GridViewHeaderCell">
<Setter Property="Foreground" Value="Red"/>
<Setter Property="Background" Value="White"/>
</Style>

Hello Chris Greening,

 You don't need to bind your style properties. You should assign static resources to them. In your case:

HeaderCellStyle="{StaticResource GridViewHeaderCellStyle}"

Binding like you have done is completely unnecessary.

I hope this helps.

Yes that works well but I want to be able to define the style of my application in one location, hence the use of Application.Current.Resources"GridViewHeaderCellStyle"], as we will have lots of different XAML's using grids

Is this possible or not?

Hi Chris Greening,

The StaticResource and DynamicResource markup extensions look for definitions not only in the current element's Resources, but their parents, as well. So if you define a resource in your Appl.xaml, you can access it from anywhere in your Silverlight application. Same goes for imported ResourceDictionaries and DynamicResource. In fact, this is the technique Expression Blend uses to store templates and other resources in auxiliary XAML files and access them.
