Yeah, it's a separate CTP. You have to "license" the MS Fluent User UI to get to the download (a single DLL).

Start here:

http://www.codeplex.com/wikipage?ProjectName=wpf&title=WPF%20Ribbon%20Preview[^]

...and follow the links.

BTW, once you download it, all you gotta do is include it in your tools panel, and you get it all.

Last I heard, it will be included in 4.0, and a preview is available for 3.5 SP1.

Calling property from silverlight page

I don't like it either, but sooner or latter (and probably more towards sooner), someone where you work is gonna put a bug in your boss' ear about it. I became more interested in it when I noticed that Texas Med Clinic had a custom app written for them, and it had a ribbonbar. What I realized is that if it's a new application that you've never seen before, it actually does help in the navigation of said program. The only thing wrong with the current implementations I've seen is that there doesn't seem to be an ability to get rid of it and go back to a UI you're more comfortable with.

Hello,

How can I call this propery in the code behind page of ASP.net(c#)?

Thanks,

You can't, since the asp.net code behind runs on the server and the
Silverlight app runs on the client.

You can use javascript to communicate with the Silverlight plugin
from HTML...

I'm using a silverlight2 datagrid in my applcation. While loading it shows very well and after the selection of one row in the grid to change the values and then click on the update button it it works very well and showing the grid very well.

But after the updation while showing the grid if we move the scroll bar up and down i'm missing the row. It shows an empty row there.

Need help to show the row while scrolling grid view scroll bar.

Can you post a small example that demonstrates the problem?

I don't know about anyone else, but I have no idea what your
"updation" code is doing...

New To silver light

28-Oct-09 20:41

First of all just to give you a little background i am a web developer with one year exp. I have went to the Microsoft site and got everything concerning Silver light but i think there is a gap i still do not know how to work with it, I was not able to continue the tutorial i got from MS.

Could any one tell me what should i know as a prerequisite.
Should i know WPF becuase i really do not know a thing about it.
Is silver light has alot of post backs on server, which leads to performance issues?Is it heavy or light?
Is there any certification on silverlight?

Thanks

Re: New To silver light

Mark Salsbery29-Oct-09 7:03

I am fresher in silver light, from where should i start ?

Knowing WPF makes the programming part of Silverlight much easier
but it is not required. If you learn to write Silverlight apps,
learning to write WPF apps will be simpler.

khalil.kamel wrote:

Only if you write code that does postbacks. Silverlight apps run on
the client - Silverlight is NOT ASP.NET.

khalil.kamel wrote:

Huh?

khalil.kamel wrote:

Currently, no, as far as I know. If you go through the
"Read Tim Heuer’s 8-part blog series on getting started"
section at the "Get Started Building Silverlight 3 Applications"
link I posted above, you'll be well on your way.

On the "Get Started" page, of course: Get Started Building Silverlight 3 Applications[^]

The documentation: Silverlight[^]

koolprasad2003 wrote:

For new development, there's no reason to use anything but the
latest version - Silverlight 3.

koolprasad2003 wrote:

Yes. Install all the items on the "Get Started" page I linked to above,
in order, and your development system will be all set for Silverlight
development.

Parsing binary TCP messages

earlgraham28-Oct-09 12:08

28-Oct-09 12:08

I'm new to silverlight. My web application "Might" attach to a TCP port that outputs a binary compressed TCP message for my web data. I'm trying to decide if I should
1)parse it in silverlight
or
2)write a middle-ware application that unpacks it and then sends it to my silverlight App.

Thanks for any recommendations.

What kind of "web application"?

For example, ASP.NET: Silverlight apps run on the client, ASP.NET code runs on
the server, so how you implement this depends at least in part on where
the code will be running.

Code is running on a client webpage. It streams data to a web user for live updates.

So this code is in the Silverlight application then?
In that case, doing everything in Silverlight seems
the most logical.

I'm curious how you are able to provide a listener socket
in an application running in a browser...

There is much I don't know about silverlight but there seem to be support for TCP connectivity in silverlight. Here is a good post on it.

http://weblogs.asp.net/mschwarz/archive/2008/03/07/silverlight-2-and-sockets.aspx[^]

My only concern is working through a binary message byte by byte to convert it into my managed code. I know there are several libraries that are not supported by Silverlight, and I hope that I don't get stuck.

Connecting, yes, but listening for connections?

earlgraham wrote:

The BitConverter class is handy for that. For strings,
the Encoding class can help.

Of course, if you're unable to parse and/or decompress the data
from Silverlight code with its limited .NET framework, then you
will probably want to consider serializing the data in a format more
Silverlight-friendly.

It will not be listening. Only requesting data from a server that hosts the data. Sorry I miss understood.

Yeah its a tough decision, there are several options for me.
1) I can edit the data server, but its an established C++(unmanaged) application. I will have several of the senior programmers grilling me on whether I screwed up anything.
2) I could write an app that uses a different port. Then all my silverlight traffic goes to that port. I convert the data and forward. (this is my preferred approach)
3) OR Convert in the silverlight app.

What fun!!!
