How To Pass 'user' Object From Aspx To Silverlight 4
Dec 28, 2010
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 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.
I have 2 user controls that is hosted by 2 different aspx pages.
example:
srcpage.aspx --> hosts the --> sourceusercontrol.ascx and destpage.aspx --> hosts the --> destinationusercontrol.ascx
I would like the values in the text fields of the sourceusercontrol.ascx to be passed on to the labels in the destinationusercontrol.ascx.
I have gone through the MSDN ASP.Net examples and i was able to successfully pass values between two aspx page using the postback URL functionality, but cannot do the same thing with the usercontrols on 2 different aspx pages.
I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
I've got a Silverlight app that has to accept some initial data when it fires up. That data, unfortunately, MUST come from XML input. In addition, I can't just pass it through the URL because the actual request is coming from a server external to my own.
So the basic setup is this: Remote server needs to launch my app. Remote server pops open a window on the user's PC with a URL directed at a CGI application that can accept the XML input. The CGI app parses the input and spits out an HTML page containing the Silverlight app with all of the init params set. Long story short: When the Silverlight app is opened this way I can't debug it. I attach to the process, but none of the break points can be hit.
I tried every way in the world to get the ASP.NET page that would normally host the Silverlight app to accept the XML in the URL but it would get stripped by ASP.NET because of security reasons and no amount of modifying the config file would fix it (since it was stemming from the other web server presumably).
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.
[code]....
I want JavaScript functionClickMenu(this) at input button [id="ButtonMaster1" @ MyMasterPage.aspx] pass its value ["Menu-1"] into text box [id="TextBoxDefault1" @ MyDefault.aspx], and then performing update / doing post-back to server ONLY FOR UpdatePanelDefault1.
I am looking forward an example code for JavaScript functionClickMenu(this).
So I am not sure what I am doing wrong. How do I get to the function within Content?
I am using IE8, Silverlight 3, ASP.NET. The silverlight control is created with the object tag as I don't think the control is an option in Silverlight 3+.
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.
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.
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'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?
