Setting a Style using Binding in XAML

Question

I need to set a Style of a given control according to some configuration value in Silverlight. I would like to have a possibility of choosing a Style for a control from two available styles (static resources). I was trying to do something like:

<TextBox Style="{Binding ABC}"/>

where

public string ABC
{
    get {return "{StaticResource MyStyle}";}
}

Unfortunately, that does not work.

Do you have any ideas?

Thanks in advance!

Cheers

You are close. You need to be binding the Style property to a property of type Style though (not a string representing a static resource lookup).

You have two options for storage of the style and this will determine what the property looks like. Either put the style in the pages resources or in the App resources, and then you ABC property will look like one of the following:

// using page resources
public Style ABC
{
    get { return (Style) this.Resources["_myStyle"]; }
}

// using application resources
public Style ABC
{
    get { return (Style) App.Current.Resources["_myStyle"]; }
}

Where _myStyle is the value the style has for its x:Key property in the resource dictionary.
