call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

What is this Mysterious Javascript code in my asp.net website doing???

  

I have an asp.net website(using Visual studio 2008), when i debug the site on my development machine, it loads well with out any errors. At this point i leave the site running in debug mode but i notice strange things. 


0). When i right click the file and check the properties, it has a URL property whose value is http://cdn1.predictad.com/scripts/publishers/suggestmeyes/predictadme.js?si=7495


1). In my sites Solution Explorer, there appears a folder called "Windows Internet Explorer". Under this folder, there is a file called predictadme.js?si=7495.

I dont have idea where this code is coming from, but the presence of the string .facebook. makes me suspicious. I have a feeling some thing fishy is happening but am really not any where near good at javascript (scripts), so am seeking

So if I had a style as follows <Style TargetType={x:Type Button}> <Setter Property="Background" Value={Binding myproperty} /> </Style> How could I achieve this in code? So far I got Style x = new Style(); Setter a = new Setter(TextBox.Property, new Binding("myproperty")l but there seems to be something wrong with the way I set up the binding, how can I correct it?
