SilverLight InitParams

04-06-2009 11:01 AM |

Hi,

 we have initparams by Xaml1.InitParameters.

How can i access to init params by the html, in :

div id="silverlightControlHost">

<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

<param name="source" value="ClientBin/SilverlightApplication2.xap"/>

<param name="onerror" value="onSilverlightError" />

<param name="background" value="white" />

<param name="minRuntimeVersion" value="3.0.40307.0" />

<param name="autoUpgrade" value="true" />

<a href="http://go.microsoft.com/fwlink/?LinkID=141205" style="text-decoration: none;">

<img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>

</a>

</object>

<iframe style='visibility:hidden;height:0;width:0;border:0px'></iframe>

</div>

??

Thanks

Hi,

You simply add the following param to the existing ones:

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

So your full HTML would look like:

<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="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>

There is a good article here http://www.silverlightshow.net/tips/How-to-pass-initialize-parameters-to-Silverlight-application-using-ASP.NET-3.5-Silverlight-control.aspx showing you how to get them in your Silverlight application.

Hi,

To helps us understand your problem, what are you working in ASP.NET, HTML or Silverlight?

Hi,

I'm working with silverLight.

but i want to know how i'm set the init params dynamicly.

Re: SilverLight InitParams

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.

Re: SilverLight InitParams

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 %>" />

Re: SilverLight InitParams

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.

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

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/

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.

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

Hi,

I have same problem with SilverLight InitParams.

 Earlier we are using 

 <form ID="Xaml1" runat="server" style="height:100%;">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div  style="height:100%;">
            <asp:Silverlight ID="Silverlight1" runat="server" Source="~/ClientBin/Shell.xap"
              InitParameters="key1=value1,key2=value2"
               MinimumVersion="3.0.40307.0" Width="100%" Height="100%" />
        </div>
    </form>

 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

 <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>

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.

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;

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" />

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%" />

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);

#### #### #### 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

<script language="javascript" type="text/javascript">
function getClientIp() {
return '<%= Request.ServerVariables["REMOTE_ADDR"] %>';
}
</script>

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

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

Re: Re: SilverLight InitParams

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.
