Hi Rob

I read your post it looks very good. Please help me if you post the complete code for this application. I'll really apperciate for this effort by your side. Because I am on learning stage and have eager to learn.

Thanks in Advance

apjrajesh:
But I'm still having no idea about "navigating between '.aspx' page and '.xaml' page.

XAML is not like a webpage. It's more like control. Are you familiar with ASP.NET or winform or WPF? If you are familiar with those technologies, you may understand what I meant by "control".. The control can't display on the browser alone. It has to be hosted on a web page.

apjrajesh:
I want to show 'shape.xaml' at the click of some button on 'default.aspx' then how to do that?".

Like I said, xaml is not like a webpage. So, You have to host shape.xaml on webpage (let's say "popup.aspx") then, you can show this popup.aspx page that has shape.xaml contetn at the click of some buttons on "default.aspx"

In short how to change root visual element of grid(of silverlight application) from '.aspx' pages?

Changing the rootvisual element from aspx page is a different thing. You can pass the parameter from aspx to Silverlight project using initParams. then, change the rootpage in App.xaml.cs. If you are not sure how to use initParams, you can search it in this forum.

Hi Michael,

Thanks for giving much needed link. Blog posted at this link is awesome. My problem of navigating between ".xaml" pages is solved.

But I'm still having no idea about "navigating between '.aspx' page and '.xaml' page. For example if I've made a silverlight project and got 'mysilverlight.aspx' page by default for getting the silverlight content. Obviously I can call 'mysilverlight.aspx' page to see the silverlight content. Now if I add new page 'default.aspx' to my application and can easily naviagate between 'mysilverlight.aspx' page and 'default.aspx' using Response.Redirect() method. Now consider that by default 'page.xaml' is shown in silverlight content through 'mysilverlight.aspx', but I want to show 'shape.xaml' at the click of some button on 'default.aspx' then how to do that?".

In short how to change root visual element of grid(of silverlight application) from '.aspx' pages?

Hi all,

I am beginner with Silverlight and have gone through various blogs, articles and e-books to know the world of silverlight.

I have following query :

"We may desire to have multiple silverlight pages in a single application. For example, consider I've two silverlight pages "Page.xaml" and "Shapes.xaml". I've a button on "page.xaml", on click of this button I want to display "Shapes.xaml" page. How to do this?

Also if I want to call a silverlight page through the click event of a button(placed on simple web page like "defaut.aspx"), how to do that?

Please help.........

I've posted a description and a solution to this problem on my blog over here.

How about loading a new usercontrol programmatically after the initial control was loaded? For example, in a button click event on my control I've tried:

Application.Current.RootVisual = New SilverlightControl1

But that doesn't seem to do anything. I expected the "current" control to change. Me.Content = New SilverlightControl1 works but Me is the original control so it technically is hanging around and acting as a parent which is not what I'm after. I want to replace the original usercontrol while remaining in the same app.

Thanks! It's fun playing with the beta. Can't wait to get proficient enough to start cranking out apps!

You guys rock! I don't know why I didn't bother trying key=value, I guess I should follow my instincts . Got it working now and it's a beautiful thing.

I still think the Silverlight Gods should consider adding a standardized parameter which specifies the entry point, i.e. which UserControl in the .xap we want to render for an instance of <asp:Silverlight > control. Unless developers aggressively hunt the info like we did, it probably won't strike them as intuitive to use key=value pairs in an InitParameters property.

Thanks, that's the official sign it's time for bed. Don't know why I didn't try = as a delimiter, seems ridiculously obvious now. Although, if you google initParams and Silverlight, your post will be the only hit that helps. They sure do index this site fast. 4:19AM in Vegas, enough coding for today.

In and <asp:Silverlight> control:
InitParameters="Label=Applicatiebeheer,Url=http://www.amercom.nl,Animate=true"

In an <object>:
<param name="initParams" value="Label=Applicatiebeheer,Url=http://www.amercom.nl,Animate=true" />

I think the intended idea is to be able to have multiple "root" controls in the same xap, and then load the appropriate one based on a setting in the params. I tried messing around with initParams setting property, but couldn't figure out the correct syntax to get e.InitParams properly populated. Anyone have a sample? You really shouldn't need separate xap files.

Re: How to use multiple Silverlight applications in one .xap file

robhouweling — Fri, 07 Mar 2008 09:10:27 GMT

@jackbond: Thanks for the example. I figured this one out myself, but I'm not really happy with the solution, so I decided to make separate XAP files for my solution.

@frefaln: This should be the solution.:

In your App.xaml, use

this.RootVisual = new Page(e.InitParams);

instead of:

this.RootVisual = new Page();

In your Page.xaml:
Create an extra constructor:

public Page(IDictionary<string, string> InitParams)

{

_initArguments = InitParams;

Init();

}

Now you can access the initParams by using this syntax:
_initParams["Label"]

Hope this helps.

Rob.

I'm stuck on the same issue and I'd love to know why this isn't documented somewhere (or at least a place where the average Joe can find it).

App.xaml does indeed accept StartupEventArgs, but its InitParameters property is Dictionary whereas the InitParameters property on an asp:Silverlight control is a String. I'd love to know how I'm supposed to get those InitParameters across -- once that happens I can do exactly what JackBond said and serve up a different RootVisual accordingly.

If this isn't possible, then I suppose each unique control has to go in its own .xap? That seems like a huge waste if that's the case.
