object tag problem in silverlight 3

Question

Hi,

  I am having trouble using object tag in silverlight 3, when I browse the page it gives me an error "Parser Error...An object tag must contain a Class, ClassID or ProgID attribute.". I am
following sample created by Jesse Liberty using Silverlight 2 in Silverlight 3. How can fixed this problem?

<div  style="height:100%;">  
   <object id="XamlObj1" runat="server" type="application/x-silverlight-2" data="data:application/x-silverlight," width="100%" height="100%" style="display:block" >
 <param name="minRuntimeVersion" value="3.0.40624.0" />
 <param name="autoUpgrade" value="true" />
 <param name="source" value="~/ClientBin/SqlData.xap" />
   </object> 
   <%--<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/SqlData.xap" MinimumVersion="2.0.30911.0" Width="100%" Height="100%" />--%>
</div>

Answer 1

2 things,

Remove Runnt ="Server" in the object tag

and

remove ~/ in the param "source", instead use <param name="source" value="ClientBin/SqlData.xap"/>

e.g:

<div style="height: 100%;">

<object id="SLExternal" data="data:application/x-silverlight," type="application/x-silverlight-2"

width="100%" height="100%">

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

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

<param name="minRuntimeVersion" value="2.0.31005.0" />

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

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

I dont think you can run <object> on server, To run it on server RUNAT=server should be specified; I think this is not supported,
If you want to access it in code behind, asp:silverlightControl can be use instead Right ?, Is there any problem in doing that ?

Answer 4

So, right now when using silverlight 3 I need to use object tag and cannot be accessed at server-side like other html controls, I need to use Silverlight 2 asp:silverlight control when I want to access it at server-side, my next question, will silverlight control be functioning ok in pc where silverlight 3 is installed??

 

Answer 5

Your objective is to acces the silverlight (Version 3) control @ server side; Correct ? To do this,

1. Register the assembly

<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"

TagPrefix="asp" %>

2.Add the control

<form id="form1" runat="server" style="height:100%;">

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<div style="height:100%;">

<asp:Silverlight ID="SilverlightControl" runat="server" Source="~/ClientBin/SilverlightTest.xap" MinimumVersion="3.0.40307.0" Width="100%" Height="100%" />

</div>

</form>

3. Using the ID, Access the control

e.g:

SilverlightControl.InitParameters = "Something";

will silverlight control be functioning ok in pc where silverlight 3 is installed?? You mean to say Will Silverlight 2 application will work in a PC where silverlight 3 is installed, if So YES is the answer

Answer 6

What you proposing does not work after followed #1 and #2?

Silverlight 2 is not installed, only silverlight 3...

Answer 7

This is because you are missing the System.Web.Silverlight.dll in the Bin folder of the ASP Net Applciation

Answer 8

 This is correct...With Silverlight 3, the need to have the System.Web.Silverlight.dll included is gone due to the object tag being used... This means that your silverlight object is hosted by an object tag instead of using the silverlight reference. System.Web.Silverlight.dll is included in the 2.0 sdk and should be located in C:\Program Files\Microsoft SDKs\Silverlight\v2.0\Libraries\Server... I would not suggest using this at all... I have stripped the reference from my project and no longer use <asp:Silverlight ........ instead, use the new standard... This takes away your reliance on an outdated control that most likely will not be used nor supported in the future.
