It doesn't but why bang your head againsts a wall using what amounts to an unsupported tag, plus IMO it's just complicating the problem as you're having to second guess how the design time form of the asp control is interpreting its properties. Just remove all that guess work.

And how does using this change the fact of getting the computer name?

No, don't use the asp:silverlight control, use the object tag as everyone has posted.

Hi All,

I hope things are a sunny around the world as it is here!

I have this working on the DEV machine, but ALAS, it doesn't work when I deploy it.

So, just to back track, what I have done is this.

//aspx

<asp:Silverlight ID="Xaml1" runat="server" InitParameters="" Source="~/ClientBin/BNA_BTSNetApps.xap" Windowless="true" MinimumVersion="2.0.31005.0" Width="100%" Height="100%" />

//hosting aspx.cs file code behing

protected string InitParams { get; private set; }
protected void Page_Load(object sender, EventArgs e)
{
    if (Page.IsPostBack) return;
    if (Convert.ToString(System.Web.HttpContext.Current.User.Identity.Name).Length > 0)
    {// set the local identity name
            Xaml1.InitParameters = "UserIdentity=" + System.Web.HttpContext.Current.User.Identity.Name;
    }
    else
    {
            Xaml1.InitParameters = "UserIdentity=NotWorking";
    }
}

//catch it in the app.cs Application_StartUp

string thisIsTheWindowsAccount = string.Empty;
foreach (String key in e.InitParams.Keys)
{
    if (key == "UserIdentity")
    {
          thisIsTheWindowsAccount = e.InitParams[key];
    }
}
this.RootVisual = new BTS_Logon(thisIsTheWindowsAccount);

//and I get sent the "NotWorking" string... Is this due to the crossdomain policy of some type?

#### #### #### EDIT #### #### ####

I found this that more or less says it can't be done unless using a caching method with "Outof Browser", but if anyone could explain this further that would be awesome. Cheers

Just another update, now using the following and involking from the silverlight app, the IP address will just have to do for now

Here's a cleaned up example of passing values to your silverlight app at runtime.

Master page:

<uc3:mycontrol ID="SLControl" runat="server" height="175" width="700" itemname="Main" />

User control:

User control code:

Public Property width() As integer

Public Property height() As Integer

Public ReadOnly Property InitParams() As String

You can do in your .aspx file:

<param runat="server" name="initParams" id="prmInitParams" />

And in your code in the behind in the Page_Load Event for example:

this.prmInitParams.Attributes["value"] = myInitParamsString;

Hi,

I have same problem with SilverLight InitParams.

Earlier we are using

and able to set InitParameters value in code behind like this.

protected void Page_Load(object sender, EventArgs e)
{

Silverlight1.InitParameters = "userID=" + this.User.Identity.Name + ", SVCAddress=" + ConfigurationManager.AppSettings["DashboardSVCAddress"].ToString();
}

Now I am using the silverlight release version 3.0 but unable to set InitParam from code behind.

Following is the code of my Main.aspx

And one more doubt, after this new release do we not use <form id="form1" runat="server" style="height:100%">
    <div id="silverlightControlHost">
        <object id="SilverlightObjcet" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
        <param name="source" value="~/ClientBin/Shell.xap"/>
        <param name="onError" value="onSilverlightError" />
        <param name="InitParameters" value="key1=value1,key2=value2" />
        <param name="background" value="white" />
        <param name="minRuntimeVersion" value="3.0.40624.0" />
        <param name="autoUpgrade" value="true" />
        <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0" style="text-decoration:none">
             <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/>
        </a>
        </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
    </form>

One more doubt in latest version of silverlight (3.0) do we not used system.web.silverlight.dll

Thanks lot.

nirav_2052003:

Hi,

I like to suggest you to add HTML stuff for silverlgiht using an HTML file template or rendering html for silverlight using string builder.

Isn't that the same as .netdan suggested? (and it's not InitParameters in HTML and you've added twice).

Hi,

I like to suggest you to add HTML stuff for silverlgiht using an HTML file template or rendering html for silverlight using string builder.

For example following is your HTML for silverlight control.

<object id="silverClient" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
	<param name="source" value="ClientBin/SilverClient.xap"/>

<param name="InitParameters" value="param1=Hello,param2=World" />

	<param name="onerror" value="onSilverlightError" />
	<param name="background" value="#00ffffff" />
	<param name="minRuntimeVersion" value="2.0.30923.0" />
	<param name="autoUpgrade" value="true" />
	<param name="InitParameters" value="param1=Hello,param2=World" />
	<a href="http://go.microsoft.com/fwlink/?LinkID=124807" style="text-decoration: none;">
		<img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
	</a>
</object>

If you write above html programmatically, you can write InitParameters values programatically.

You're correct, it's called InitParams, just like I mention in my article: http://mark.mymonster.nl/2008/12/22/restarting-the-silverlight-object-with-different-initparams-from-within-silverlight/

Re: SilverLight InitParams

pkr2000 — Tue, 30 Jun 2009 11:05:20 GMT

Just to be clear, isn't the param called "InitParams" and not "InitParameters"?

I'm posting because I've just spent 5 mins scratching my head wondering why I couldn't see any values!

Re: SilverLight InitParams

MarkMonster — Tue, 07 Apr 2009 05:55:39 GMT

This mechanism would work as well. But this is from Server Side code. I though he wanted to control this from a Silverlight application. In that case you would only be able to make use of Javascript to control the initParams.

ssawchenko — Mon, 06 Apr 2009 23:12:52 GMT

Couldn't you inject the dynamic parameters the same way you would with any other html code?

[My syntax may be wrong since I've only done a little ASP years and years ago]:

<param name="InitParameters" value="param1=<%=myparam1 %>, param2=<%=myParam2 %>" />

I've written an article about how you can restart your Siverlight Application using Javascript. Restarting the Silverlight Object with different initParams from within Silverlight

Re: SilverLight InitParams

.netdan — Mon, 06 Apr 2009 16:07:21 GMT

Your working in Silverlight, are you trying to set the InitParameters in Silverlight or something else like javascript, HTML, ASP.NET? It is this that is confusing me as I couldn't see any reason to set the init params in Silverlight.
