how to implement a functionality built in WPF/E on the wpf platform

  Hi Abhas,

  Mr. Rideout is correct (after all he is a PM ).  However, there is a way to do it, it is just not a direct implementation.  This is an extremely round-about way of addressing your specific problem, however, if you HAVE to call that JavaScript method, you could:

  1. Have your WPF application call a webservice that sets some flag that signals the JavaScript method must be called.  NOTE: You cannot call the webservice from the actual XAML, you will need to do this in the code behind.
  2. Have some AJAX code affiliated with your WPF/E interface that listens for the flag.
  3. When the flag comes through, execute the JavaScript function.
  4. Return the results (if needed) through javascript that calls another webservice that communicates with your WPF application

  It should be noted that your WPF/E and WPF applications will need some identifier to signal that they are part of the same user experience.  As I mentioned, this is an extremely roundabout approach and generally when I run into problems that require something this complicated, it's a sign that I have overlooked something in my architecture. 

  However, I actually ran into a case where I needed to use this approach.

  I hope this helps,

  is there a way to call javascript functions from xaml code in wpf based application

  No, not from a WPF ("Avalon") application. You might follow up on the WPF/Avalon discussion board: http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=119&SiteID=1

  hi chad, I am writing one function in javascript in the wpf/e based application and I want to call that function from the wpf application, for that I am integrating the wpf and wpf/e based application and for integration I have to add the reference of wpf/e based application in the wpf application, at this step I stop as he reference of wpf/e based application cannot be found . Please can you guide me further as after adding the reference If I am able to create the object of the wpf/e based application then definitely I will be able to call the javascript function from wpf.

  Hi Abhas,

  You can use the events for a XAML element and then use the syntax: javascript:[functionName]

  If you go to the WPF/E SDK, there is an example in the "Loaded" event.

  If this answers your quesiton, please select "Mark as Answer" otherwise, please post a followup question.
