I have decided that all my WPF pages need to register a routed event. Rather than include
public static readonly RoutedEvent MyEvent= EventManager.RegisterRoutedEvent("MyEvent", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(BasePage));
on every page, I decided to create a base page (named BasePage). I put the above line of code in my base page and then changed a few of my other pages to derive from BasePage. I can't get past this error:
Error 12 'CTS.iDocV7.BasePage' cannot be the root of a XAML file because it was defined using XAML. Line 1 Position 22. C:\Work\iDoc7\CTS.iDocV7\UI\Quality\QualityControlQueuePage.xaml 1 22 CTS.iDocV7
Does anyone know how to best create a base page when I can put events, properties, methods, etc that I want to be able to use from any wpf page?
Here's how I've done this in my current project.
First I've defined a class (as @Daren Thomas said - just a plain old C# class, no associated XAML file), like this (and yes, this is a real class - best not to ask):
public class PigFinderPage : Page
{
/* add custom events and properties here */
}
Then I create a new Page and change its XAML declaration to this:
<my:PigFinderPage x:Class="Qaf.PigFM.WindowsClient.PenSearchPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="clr-namespace:Qaf.PigFM.WindowsClient"
/>
So I declare it as a PigFinderPage in the "my" namespace. Any page-wide resources you need have to be declared using a similar syntax:
<my:PigFinderPage.Resources>
<!-- your resources go here -->
</my:PigFinderPage.Resources>
Lastly, switch to the code-behind for this new page, and change its class declaration so that it derives from your custom class rather than directly from Page, like this:
public partial class EarmarkSearchPage : PigFinderPage
Remember to keep it as a partial class.
That's working a treat for me - I can define a bunch of custom properties and events back in "PigFinderPage" and use them in all the descendants.
