How to set parameters for a silverlight object from asp.net on object loading

[CSurieux]

Hello,

I want to include silverlight objects in my web site, (this site is using radAjax.net intensivelly).
I am new to silverlight (2 apps :) )
I create the silverlight <object> from codebehind and I want to know if there is some way to set initial parameters to this object which could be injected when the xap is loaded ?

Is there a way for the Telerik object to communicate using Ajax.net with my page instance which is ajaxfiied with RadAjaxManager.

Moreover, what is the Telerik recommandations concerning the best way for the silverlight/telerik control to communicate with its server in term of execution speed, easy dev, easy deployment: you present WCF,ADO.NET,Web Service, RIA ?

Thank you for recommandations

Hi Christian Surieux,

 You can sue the "initParams" parameter for the silverlight object to pass parameters to the Silverlight application when it is initialized:

Generally there is no direct integration between the Telerik Ajax and Silverlight controls. We have not found many scenarios for which we can provide support out-of-the-box because these kind of requirements tend to be application specific. One exception is the upload control:

If you want to communicate between JavaScript and Silverlight, you can use the Html Bridge:

As back-end communication we cannot suggest a particular approach as "best' because again this may very much depend on your application.

Things to keep in mind:
 - The .NET RIA Services will provide the best integration with Silverlight, but is still in beta and hosting it is a problem. (Requires full trust)
- The ADO.NET data services 1.5 are still in beta and cannot be used in a production environment. The 1.0 version lacks a lot of things that an application may need. Generally they allow exposing data in a very elegant way.
- The standard WCF services is a good choice in the short term - they are available now and are supported.

Unfortunately I cannot suggest what may be best in your case.

Kind regards,

Thank youMiroslv,

Very helfull at my level of Silverlight knowledge.
I especially appreciate the point concerning RIA full rust necessity, ADO.NET and WCF.

Silverlight is interesting but still seems to be years beyond Flash ?
Telerik is a great help starting with it.

Best regards
