问题 I am continuing to program some kind of keyboard navigation in my simple graphic program (using C#). And I ran into trouble once again. My problem is that I want to process the keyboard input to move a layer around.

问题 In a table row ( <tr> ) there are several input elements. I need to execute some JavaScript code when the tr loses focus (but not when the user just switches to a different input element in the same tr). I use jQuery.

Here is the XAML: <phone:PhoneApplicationPage x:Class="WP7Sample.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml

Now I wish to implement a functionality like: Wherever I am on a map, whatever zoom level is set, whenever i click on a button (or some external event), focus should be shifted to line i have drawn (i.e. indirectly on the two waypoints) Secondly, the zoom level should be set such that portion of a map containing those two waypoints should be visible.
