We have now added a 'photo page' to our XAML application.

Before we can make use of this new page, however, we have to provide a mechanism to navigate from our main page to the photo page.

A benefit to using the LayoutAwarePage type is that backwards navigation is automatically taken care of.

In this video, I will show you how to add navigation between 2 pages.

By pavel@techytube, for more from this author visit: http://www.techytube.com/author/pavel Block objects provide a way for you to create an ad hoc function body as an expression in C, and C-derived languages such as Objective-C and C++. In other languages and environments, a block object is sometimes also called a closure. Here, they are typically referred as blocks, unless there is scope for confusion with the standard C term for a block of code. You use the ^ operator to declare a block variable and to indicate the beginning of a block literal. The body of the block itself is contained within {}, as shown in this example (as usual with C, ; indicates the end of the statement): int multiplier = 7; int (^myBlock)(int) = ^(int num) { return num * multiplier; }; Notice that the block is able to make use of variables from the same scope in which it was defined. If you declare a block as a variable, you can then use it just as you would a function: int multiplier = 5; int (^myBlock)(int) = ^(int num) { return num * multiplier; }; int result = myBlock(4); NSLog(@result = %d, result); // will output result = 20 You can find more about blocks on the following web page: http://developer.apple.com/library/ios/#documentation/cocoa/Conceptual/Blocks/Articles/00_Introduction.html$
