Good Day All
I have another question. I have a Silverlight application and in one of the Silverlight pages i am hosting an Asp.net Page using a RadhtmlContainer(Telerik). I created a Cookie in Silverlight like this
public static void SetCookie(string key, string value)
{
DateTime expiration = DateTime.UtcNow + TimeSpan.FromDays(2000);
string cookie = String.Format("{0}={1};expires={2}", key, value, expiration.ToString("R"));
HtmlPage.Document.SetProperty("cookie", cookie);
}
and i have the same generic function to access it like this
public static string GetCookie(string key)
{
string[] cookies = HtmlPage.Document.Cookies.Split(';');
key += '=';
foreach (string cookie in cookies)
{
string cookieStr = cookie.Trim();
if (cookieStr.StartsWith(key, StringComparison.OrdinalIgnoreCase))
{
string[] vals = cookieStr.Split('=');
if (vals.Length >= 2)
{
return vals[1];
}
return string.Empty;
}
}
return null;
}
so i am trying to access this cookie in an asp.net page that is hosted on the the html Container , but i dont find the cookie.
Basically what i want to Achieve is
i want to access a value that is being created in Silverlight e.g "userid" "Username" normally i store it in the Cookie , so now i want to do a database insert , i need to do that insert from that asp.net page, but i cant get hold of that cookie value.
Thanks

What do you see in HtmlPage.Document.Cookies when you enter the GetCookies method? It would really help if you set a breakpoint there and told us what was in that part? Plus, and I know this seems obvious, but make sure that the SetCookie method is called before you call GetCookies.

Good Evening Pete
Thank you for your kind response.
The First thing i do is to set the Cookie when the User has Just Logged in and after that that the User will be redirect to a Welcome page. There are Menu's that are visible for the User to select , and one of them will lead to a Silverlight page that will require the Cookie value that has been set at Login.
So the above explanation your last point that i should first set the Cookie and Access it later
To answer the first question about the htmlpage.Document.Cookies , it has an empty string i am not sure why.
Thanks

From your description, the cookies are added by the website and not by Silverlight. It looks like you are trying to read the cookies created in the ASP.NET side, in your Silverlight code. According to MSDN[^], Cookies are disabled by default for security reasons. Use WebClient instead.

Can you pass the cookie value into the silverlight app as an initial parameter?

I have a SL site that is structured like
Corporate
- Company1
- Company2
- Company3
- Company4
Entry to the site is www.corporate.com
Each company now wants to basically skin their area of the site with thier company identity and to access their area directly skipping the corportate.com page. I know I can change skins (never having built a skin this is an assumption) so what is the recommended method of going directly to the company pages based on the URL.
All will use the same xbap, wcf and database it is just the entry point for the companies.

Pfft alreay half way there I implemented navigation right from the start, just never went past the minimum required for our needs. thanks...

What, that's what lives in my clientbin folder and thats what gets deployed (along with the dafault.aspx), when did they go out of fashion, link required. Your had better mean you are taking the mickey or I've got some serious reading to do.

Ohhh the XAP? XBAPs are WPF browser applications...Silverlight is recommended over XBAPs, although you can still do them.

It turns out that the link does not actually help me, I don't expose the url eg www.corporate.com?companyid=1 However I guess I should be able to use mymapper to hard code the url. Pick up www.corporate.com/CompanyName in mymapper and deal with it.

The domain "www.corporate.com" doesn't need to be in the code, does it?
According to your original post, you should only need something like this
<navigation:Frame.UriMapper>
<uriMapper:UriMapper>
<uriMapper:UriMapping Uri="/Company1" MappedUri="/Views/Company1.xaml"/>
<uriMapper:UriMapping Uri="/Company2" MappedUri="/Views/Company2.xaml"/>
<uriMapper:UriMapping Uri="/Company3" MappedUri="/Views/Company3.xaml"/>
<uriMapper:UriMapping Uri="/Company4" MappedUri="/Views/Company4.xaml"/>
</uriMapper:UriMapper>
</navigation:Frame.UriMapper>
or better yet, to not hard-code company names in the code...
<navigation:Frame.UriMapper>
<uriMapper:UriMapper>
<uriMapper:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/>
</uriMapper:UriMapper>
</navigation:Frame.UriMapper>

How do you eliminate the # requirement. Currently the nav wants
www.Corporate.com/#Company1

If you create and build a SIlverlight Navigation Application from the visual Studio project templates and run it, you'll see there's no "#" requirement.
I'm not sure where that would come from

Good assumption - yes you can[^].
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Hi all,
I am still digging into WPF and last night have a look around with User Controls.
If I said that User Controls are more likely the templates, where I can reuse later time, what you think? Any comments really appreciate.
Thanks
I appreciate your help all the time...

I personally would not associate UserControl with the word "template" in WPF/Silverlight, since a "template" in these frameworks has a specific meaning.

Thanks for the reply.
May be that I have not enough experience with WPF. I agreed with you, comparing with ASP.Net and so on, word template is not relevant. Basically it has a different meaning.
Why I wonder is that I can use the same XAML in different places as well. Is there anything in WPF named as 'templates' ?
Thanks for the link as well, sounds good it is.
I appreciate your help all the time...

Hi,
I am new to MVVM and trying to implement it in my application.
I have a develop a GUI which will interact with the Hardware through some protocol. This is first experience under this space.
Just to keep things simple, consider I have a hardware which contains Voltage and Resistance parameter at different sections of the hardware.
View
----
So, I have total 5 sections. Each of them contains 15 different Voltages and Resistance.
In my WPF GUI, I am representing these 5 sections in a tab control.
I have created a user control(PowerControl) that contains 2 sliders for Voltage and Resistance. Voltage varies from 0-120v and Resistance varies from 1-10 ohm.
Each of the sections in the tab control contains 15 user controls.
Model
-----
I am planning to create a class Power which has 2 properties for voltage and Resistance.
ViewModel
---------
I am planning to create a class 'PowerViewModel' to represent the Power model. It will have two properties which will have INotifyProperty changed event.
The change from the slider has to be conveyed to the hardware and it is done through a set of uniquely identified parameter.
Such as if a slider on the PowerControl of section 2(tab2) is moved, it 'll be represented as "PC2, section2, value of slider". So, its a combination of these three things and I used to send it the hardware which displays it in the hardware display.
Here are my questions.
1- Where should I write the unique ID's? Should it be in the Model or ViewModel?
2- How should we bind the slider as per their ID's?
3- How does my Model know which slider has been moved?
4- How can we apply MVVM here?
Thanks in advance and please feel free to ask for any clarification on this.

I'll take a stab here...
If the IDs don't need to be in the model then they should be used in the viewmodel.
But, if you have separate objects in your view model - each associated with individual PowerViewModel objects, then you can bind those to each user control. Then you don't need IDs and the model knows what slider is moved.

For MVVM you're kinda doing it the wrong way around - you should create your VM first and then design a view. Anyhow, I know lots of people work better visually, so:
You have five sections each with a collection of 'Voltages and resistances'
So you want a SectionViewModel that contains a collection of VoltageAndResistanceViewModels - each of which has a Voltage property and a resistance property -which utilise INotifyPropertyChanged
Then you want another ViewModel that contains a collection of the SectionViewModel
I'd say that when you instantiate each of your ViewModels you'd need to tell them which unique Id for the hardware they are representing. This information (I would htink) would be contained in the model as a series fo collectins - so you would construct your collection of ViewModels based upon these collections, hence the Model has the unique Ids, which are referenced by the viewModels
Each slider would be bound in Xaml to the appropriate property of the particular VM to which the View is bound
When the property of the Vm is changed, if necessary that's the time to adjust the property on the model - the model can then do whatever it does in order to update the machine's value.
Hope that helps at least a little!
