I have the code below is very simple with style resources in wp7,
<Style x:Name="image_find" x:Key="ImageFind1" TargetType="Image">
<Setter Property="Source" Value="display/pen.png"/>
</Style>
I want to change the source value of setter, for ex. "display/tool.png" when I want beside runtime in code of my app, take in mind that I need image beeing in style :)
I am running something like this,
image_find.Setters.SetValue(Image.SourceProperty, "display/tool.png");
or something like,
style = App.Current.Resources["image_find1"] as Style;
style.Setters.SetValue(Image.SourceProperty, "display/tool.png");`
and I am getting NullReferenceException
and the app breaks...

It really depends on where your Style
is located, and you need to use the x:Key
to find the Style not the x:Name
If the style is in your Application Resources (App.xaml) this should work
var style = App.Current.Resources["ImageFind1"] as Style;
If its within the context of your Window/UserControl
you will use FindResource
var style = FindResource("ImageFind1") as Style;
