I've got a Page in a Frame Control. I want to change it by clicking button in a current page. How can I do it?
I've got a full-screen desktop application on WPF (without any window's title and system buttons).
you can use NavigationService.Navigate() method to navigate through pages in a Frame.

Lumia 730/735 have the on-screen navigation buttons, and this bar can be hidden/displayed using the swipe upward screen gesture. System apps correctly process the moment when this bar is hidden or displayed - they increase/decrease the height of their current page accordingly.
I have been developing a WP8 Silverlight app to manage checklists for 2 years. Recently I've obtained a Lumia 730 phone, and I'm testing my app on it. As I can see, some pages of my app does not fit the available screen size automatically. Look, for instance, at the following picture - I can't scroll a checklist to see the very last item when the navigation buttons bar becomes visible (the right screen):
As I understand, this happens because of some settings and non-standard page layout I use. My question is the following: how can I detect the moment when the visibility of the on-screen navigation buttons bar changes to correct the layout of my page from code?
Unfortunatelly, as far as i know, you cannot get any information about the bottom on-screen navigation status bar in Windows Phone 8. This is a good reason to develop a Windows Universal application. Propably this is what Microsoft wants from the developers.
I am trying to write a WPF application. The general outline of the application is as follows: There is a main window(Note that the main window is a full screen application) and there are several pages(Possibly 25) and I want to navigate from one page to another with a button click event on each page. What will be the best way to achieve this?
I have tried creating a Frame on the MainWindow and then use the frame to display pages, but my problem is that I can not navigate from one page to another from a button click on the pages. I am new to this and I would appreciate any help.
You could of at least tried a Google mate, this information is abundant, but because you thought typing a paragraph here was easier, I shall save you the trouble.... http://paulstovell.com/blog/wpf-navigation
I'm using the Navigational Framework in Silverlight 4. I'm starting to believe that this was a mistake as the browser buttons are really screwing things up for users. For instance, when a child window is opened the user believes they can close the window by pressing the back button. It doesn't close the window obviously, it just navigates the parent page back a step. The end result is a messed up data set. I'm fed up with the little control I have over the navigation of my application; forward and back buttons are anachronistic. Web applications don't work that way anymore. Please someone tell me how I can disable their functionality; that is, cancel navigation when it is started from one of these buttons.
Remove this code from your html page which holds your silverlight XAP:
<iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe>
This is the history frame.
You will likely have to do this in the actual web/asp.net page, as Silverlight has no real control over the browser.

Is this possible?
I used a Frame control and:
show(ex:showwindow.xaml)
But I get this error:
root element is not valid for navigation
sure you can navigate (show) a window by using:
YourFrame.Navigate(YourWindow);
However I don't like much this multi-window approach, better create some user controls for segmenting your application.
It is more common to use the Page class with the Frame control. Windows, in WPF are the top level items, with their own titlebar, chrome etc. Also, the Page can tap into the NavigationService provide by the framework.

I would like place a silverlight contol on an HTML page --- something about the size of a typical calendar control. However when the user selects a day on the control a bigger canvas opens up on top of the containing page --- something like a modal dialog box that you might find with the AJAX.
I'm wondering if this is even possible with Silverlight, or is the silverlight content limited in size to the DIV element on the host page?
UPDATE: after doing some poking around, I think the answer will involve using the ChildWindow control introduced with Silverlight 3. However I'm still at a loss how to have the ChildWindow display ontop of the existing content
I know one way, you will need javascript event on the page itself to expand a silverlight object to fit the whole page then build you silverlight event accordingly.
