I am new to silverlight and I am wondering if it is possible to access silverlight object data from the aspx page that host it. Or have silverlight write to a hidden field on the page on client side.
What I am trying to do is to use silverlight to upload file via WCF (client to WCF Service directly instead of posting data back to the web server then forwarded to WCF service). When uploading a large file, user can still do some data entry etc. And once the upload is done have it write some data return by the WCF service to the aspx's hidden field and postback to the server on submit.
We have an ASP.Net 2.x web site. We want to migrate it to Silverlight full frame application. However, there is no way we can go away in a corner and redo every web page in SL right off the bat.
What I would like to do is build the chrome of the app (main page, dashboard, login, common system/config screens, main menu) in SL and be able to open existing .aspx pages in the main content SL frame.
From what I see there is no way to do this. I thought the Webbrowser control in SL4 would be the answer, but apparently that only works if your app is run out of browser.
So, what is my best recourse? It seems like I will have to create some type of .aspx page that hosts the .XAP and pass in the page I want it to load?
I have an aspx page and I want to access an application on the client after seeking user permission. Both the windows application and the website are to be made in VB.NET.
EDIT: Here is the problem. From my .aspx webpage in vb.net, a visitor clicks on a link on my site, and if my winform is not already loaded on their desktop, it is then loaded with the users permission. This application should auto-load on the user's site at boot up time and always be in the background running. Make it an extremely thin client, taking the least cpu and bandwidth from the user, and running as a silent background process until needed.
Whenever the user visits one of my many websites, IN ANY BROWSER, somehow - the app running in the background communicates with the .aspx on one of my sites, and exchanges a silent username password identifying client winform app to the online .aspx app on my website.
Then the .aspx on my site PASSES a url such as "www.somewebsite.com" to the app running in the background, the background app then does a http request from the client's computer, not from my .aspx server, so the client's cookies and ip are visible to "www.somewebsite.com" server. The client collects the html for that page, stores it as a string, and also saves the ascii of that webpage as another string.
Both strings then are PASSED BACK to my .aspx website that the client is visiting, and the .aspx app then stores these results in a database.
I am able to access the controls of ".aspx" file in ".aspx.cs" directly without any declaration in ".aspx.cs" or in designer.cs. How is this possible? This is happeing only if I open website as using File System.

How btnSave is being recognized by .cs file without defining it anywhere as an object of System.Web.UI.WebControls.Button?
I am working on a website where when the user logs in, I select their database based on their username. Currently I have a list of all databases in the web.config and I select the Database ID from the username and then read the database string from web.config. What is the most optimal way to implement this scenario?
currently I:
- store the Database ID in the session object
- the Session object expires after like 5 minutes so i have to read the Database ID from the online database based on the username and regenerate the Session["DatabaseID"] again.
- there are some security issues with the Session ID, so I started clearing the Session in !(Page.IsPostBack) and I generate the Database string again.
Where shall I store the DatabaseID and the database connection string so I can easily reuse it once the user has logged in?
Currently I am storing my username and password (passwordFormat="SHA1") credientails in my web.config. I would like to figure out how to access them in an xml file that I have stored in my App_Data directory rather than the web.config file because I do not want my application restarting everytime I manually add a user (small list of 5 authorized users for the CMS section).
I have a Silverlight application hosted inside an asp.net website. In my silverlight applicaiton, if I select a theme. Then, theme changes will gets fired. I want to get notified in asp.net web page, when the theme changed event is fired inside the silverlight application. Note: Also, I don't want to use a data base to maintain the state of the application.
How to embed silverlight xap into aspx page. I have created students database. I want to keep search option to find student name. It should be done in silverlight. I want to embed that silverlight in aspx page.
First, we are constrained to using an existing web framework that handles authentication and authorization. The web project uses forms authentication and writes to an encrypted cookie. The user information is exposed to the aspx pages as a property:
LoggedInUser.Current
This has several properties including the userId and role list.
I've looked at using initParams, but haven't been very successful there (edit: I couldn't do it dynamically originally). I've created a simple POCO entity with a [Key] attribute, but I need to at least be able to pass the userId from the aspx page to the imbedded silverlight.
What is the easiest way to pass a dynamic object from aspx to silverlight 4?

Then used Slugster's example to use the values on the Silverlight side.
Warning: Passing user information via init params exposes the info as plain text to the user viewing the page (they just have to view the source). We ended up using an authentication domain service and using the same user object as the aspx
i have made a user control carrying a grid which is showing different uploaded images , description etc. I am putting this in another aspx page and want to fetch the values of the silverlight grid. I have made a class file for that but unable to get the grid collection.
I've created a silverlight application, MainPage.xaml has silverlight controls. The code behind of it will be definately in MainPage.xaml.cs file. When creating a silverlight app, I've selected a default web project wherein this silverlight app will be hosted and run. After all my work in MainPage.xaml.cs file, I want to integrate it in my default.aspx file. As i understand, I need to give reference to xap file in this aspx file. I tried accessing
<asp:Silverlight ID="xx" runat="Server.. />
tag but had no luck. This tag does not come up, Am i missing to add reference to any silverlight dll to my web application. Or is this tag applicable for Silverlight 2.0 and not 3.0 which I'm using:
We have a silverlight/asp.net application which communicates with WCF to fetch data. Now we are facing a problem where in the silverlight component is taking some time to initialize after the asp.net page life cycle is completed.We have tried tracing all the events and found that there is a time lapse between the aspx page unload event and silverlight initialize event. This we have tried with even a simple application (hello world) but still have found the same result.There is nearly 3-4 seconds delay i.e the silverlight component initialization starts 3-4 seconds after the page unload event ends.
I have an aspx masterpage that I would like to use in Sketchflow in ExpressionBlend as a Silverlight project. I am totally out of my comfort zone here and am not even sure how to ask this question. This masterpage has a Header and a Footer and the middle section will contain the Content - which will actually be Silverlight. Is there some easy method to bring the design (aspx) into Sketchflow to use?
I'm developing a web site, and i'm using infragistics for web, but I want to use in some pages silverlight controls (Infragistics too). Is there a way to access a silverlight control's properties and methods from an aspx page?
