Inheritance, DependencyProperty and Custom Control...

[NewsBot]

Hi !

 

I have a problem with two custom controls that I want to make :

• *the first one is a Page derived controls, which contains a TabControl.
  
• the second one is a HeaderedContentControl, made to be contained by the first one.

The purpose is to navigate to a page and directly display a tab.

 

So, the navigation to a tab is not a problem. The problem is to have different pages with different tabs... :(

 

I have made this classes (I just copy relevant code) :

 

[ContentProperty("MyTabs")]

public class MyPage : Page

{

*** public List MyTabs

*** {

******* get { return (List)GetValue(MyTabsProperty); }

******* set { SetValue(MyTabsProperty, value); }

*** }

*** public static readonly DependencyProperty MyTabsProperty =

******* DependencyProperty.Register("MyTabs", typeof(List), typeof(FrameworkElement), new FrameworkPropertyMetadata(new List()));

 

*** static MyPage()

*** {

******* DefaultStyleKeyProperty.OverrideMetadata(typeof(MyPage), new FrameworkPropertyMetadata(typeof(MyPage)));

*** }

 

*** public MyPage() : base() { }

 

*** public override void OnApplyTemplate()

*** {

******* base.OnApplyTemplate();

******* TabControl tabControl = GetTemplateChild("PART_TabControl") as TabControl;

******* if (tabControl != null)

******* {

*********** Binding tabsBinding = new Binding();

*********** tabsBinding.Source = this.MyTabs;

*********** tabControl.SetBinding(TabControl.ItemsSourceProperty, tabsBinding);

******* }

*** }

}

 

 

public class MyTab : HeaderedContentControl

{

*** static MyTab()

*** {

******* //DefaultStyleKeyProperty.OverrideMetadata(typeof(MyTab), new FrameworkPropertyMetadata(typeof(MyTab)));

*** }

*** public void Reset()

*** {

******* //...

*** }

*** public void Compute()

*** {

******* //...

*** }

}

 

 

 

And, when I use this classes like this :

 

 

***

*******

*******

***

 

 

 

*******

*******

*******

*******

 

 

 

*******

*******

*******

 

 

 

... my two frames contain the all seven tabs.

 

Actually, when I add a tab in MyPage1 or MyPage2, the tab is added in the MyTabs property in MyPage...

 

I don't know how to tell WPF that the MyTabs property is different for each derived class.

 

Somebody have an answer ?
