Silverlight widget become blank when drag/drop

[Google Code Exporter]

What steps will reproduce the problem?

1. When you drag and drop silverlight widget (digg for example), it become 
blank when drag/drop


Solution to this problem :

In my implementation of dropthings for poshboard, I used literaloutput 
instead of silverlight container in the widget aspx page, and call the 
classic html code for loading the xapfiles, and all is ok with silverlight 
drag/drop (and loading is fast)

I can provide some code samples on this if you think it's usefull for the 
main dropthings project ?

Sure, please send me the fix. 

Or you can join this project and implement the fix yourself.

Would love to help on dropthings, but I'm unfortunately too busy at this time 
to help 
properly. Count me in for March.

My method of silverlight hosting is quite simple but works well :

1) Instead of an ASP:Silverlight control in the widget .acsx, I use a literal 
output 
, as in your html widget :

***
<center><asp:Literal  ID="Output" runat="server" /></center>
****

2) in the "OnPreRender" function, I read a HTML on the server (by the way, this 
is 
the basic html rendering page of a silverlight control, I attached the file for 
example)

***
protected override void OnPreRender(EventArgs e)
    {
        base.OnPreRender(e);
        StreamReader HTMLSilverlight = new 
StreamReader(Server.MapPath("~/silverlight/mySilverlightControl.html"));
        string targetHtml = HTMLSilverlight.ReadToEnd();
        this.Output.Text = targetHtml;
    }    
***

3) I eventually use a "height" state for the widget, I can change the height 
property 
in the html code before loading it in the output.Text (not mandatory if you set 
the 
height directly in your silverlight control)


That may not be the best way to achieve this, but this work very well : 
drag/drop of 
silverlight control works like that, and loading is pretty fast.

Let me know if you want additional info.

regards,

antoine

I experience slightly different behaviour. It was always blank for codeplex 
version ,
but the latest version extracted from svn here at google does differ. After the 
very
first  drag/drop there is some delay  for Silverlight widget to refresh itself (
blank, message "Loading Digg Stories" , refreshed ). However, subsequent 
drag/drop
results in a blank widget. Browser - Firefox in my case. Perhaps, it is a minor 
thing
 which may fixed without changing ASP:Silverlight approach.

In fact, in Internet Explorer the problem does not exist for my configuration,
Silverlight digg widget is always refreshed.

Yes it works for IE, but not in Chrome/Firefox. That's why I used the 
literaloutput 
that works in every browser. 

I agree that this could be fixed with changing ASP:Silverlight, but I didn't 
found a 
way yet.
