What is new with Q3 2008 release?

[Eric Schoenholzer]

My application has stopped working. 

I get an error like "Transition Target property have to be Panel object. Please set Transition Target to Panel !" or "Object reference not set to an instance of an object" when I use now "service.Navigate("Page");"

The problem is, that there no information what has changed between this and the last release.

The help has no pratical information, the examples reference the Telerik Site without source code.

 

Any information or examples available? It seems Telerik was in hurry to push the Q3 release.

 

Thanks

Eric

Hello EricSch,

Thank you for pointing this out. We will update the online samples to provide a downloads for them.

As of Q3 release the target of the page transition should inherit from Panel. Is suppose that in your application you are setting as a RootVisial a UserControl, or a RadPage. Now the recommended way is to set a RadFrameContainer element as a RootVisual and to load the start page directly in the frame container. See the following code:

 private void Application_Startup(object sender, StartupEventArgs e)
        {

            this.RootVisual = new RadFrameContainer();
            NavigationService service = NavigationService.GetNavigationService(this.RootVisual);

            service.Navigate(new LandingPage());
        }

Please let us know if this is the problem in your scenario.

Thanks Valentin,

Then I souldn't use anymore a RadPage (inside a RadFrameContainer) ?
What type has the "LandingPage"?

And why the syntax 'service.Navigate("LandingPage");'  doesn't work anymore?
Needs the "LandingPage" to be preloaded or available in the history?

Thanks
Eric

I found the relase notes here:
http://www.telerik.com/products/silverlight/whats-new/release-history/q3-2008-version-number-2008-03-1105.aspx

But the link in the download section shows to the wrong place:

Thanks

Hi Eric,

thank you for the reported "broken" links - we will update the site.

LandingPage is just the name of the page that I used as an example. It can be any Control that inherits from RadPage.

>> And why the syntax 'service.Navigate("LandingPage");'  doesn't work anymore?

It should work. Do you have a sample where this is not working? Basically the service will try to find a class with that name "LandingPage" inside the current assembly and will try to instantiate it. If this is not working then maybe the name of the class is wrong?

I have changed it to 

service.Navigate(new ClassName());

and its working now.

>>Basically the service will try to find a class with that name "LandingPage" inside the current assembly and will try to instantiate it.
>>If this is not working then maybe the name of the class is wrong?

The same code has worked before the Q3 Release. I will try to submit a support request with the sample code.

Thanks

Is there now somewhere a link for downloading the sample code?

Thanks

Yeah, any sample code would be great, I click the link on the Navigation demo but it brings me to the Telerik.com homepage, and all the examples in the download point right to that demo. :D

[Danny Joe]

The download link on the page navigation demo is still broken. It goes to the home page and not the source for the demo. So there is currently no example for page navigation and docs have no API reference, making it very difficult to know how to set properties and work with the control.

Hi Danny Joe,

We will upload the source code of the example under the client.net accounts shortly. Thus, you will be able to download the code from your account.
