Binding to context menu

[ruty]

Hello,
I have application from yours(from last post).
and I want to transfer  the radContextMenu definition from the XAML filt to the CS file:

in the XAML:

<telerikNav:RadContextMenu.ContextMenu>

<telerikNav:RadContextMenu x:Name="ContextMenu" ItemClick="ContextMenu_ItemClick"

ItemsSource="{Binding Items, Source={StaticResource MenuModel}}"

ItemTemplateSelector="{StaticResource ItemTemplateSelector}" />

</telerikNav:RadContextMenu.ContextMenu>

 and I write in the CS file:

            RadContextMenu ContextMenu = new RadContextMenu();
            ContextMenu.ItemClick+=new RadRoutedEventHandler(ContextMenu_ItemClick);
            MenuModel menu = new MenuModel();
            MenuItemCollection y=  menu.Items;
            Binding bin = new Binding("Items");
            bin.Source = y;
            ContextMenu.SetBinding(RadContextMenu.ItemsSourceProperty,bin);

but the context menu don't show!!!
Can you help me???
Thanks.

Hi ruty,

You need to set the RadContextMenu.ContextMenu attached property:
DependencyObject elementWithContextMenu = ...;
...

RadContextMenu ContextMenu = new RadContextMenu();
ContextMenu.ItemClick+=new RadRoutedEventHandler(ContextMenu_ItemClick);
MenuModel menu = new MenuModel();
MenuItemCollection y= menu.Items;
Binding bin = new Binding("Items");
bin.Source = y;
ContextMenu.SetBinding(RadContextMenu.ItemsSourceProperty,bin);

elementWithContextMenu.SetValue(RadContextMenu.ContextMenu, ContextMenu);

Thanks,
But I don't understand Why the intention in the line:
DependencyObject elementWithContextMenu = ...;
...
What needs to define there??
Can you give me a example???
Thanks.

Hi ruty,

To use the context menu you need to assign it to an element. When this element is clicked, the context menu will open. For example the following code:

<Rectangle x:Name="rect1">
    <telerikNavigation.RadContextMenu.ContextMenu>
        <telerikNavigation.RadContextMenu ... >
    </telerikNavigation.RadContextMenu.ContextMenu>
</Rectangle>

is equivalent to:

RadContextMenu contextMenu = new RadContextMenu();
...
rect1.SetValue(RadContextMenu.ContextMenu, contextMenu);

Thanks,
 I  assign the context menu to an element (button) thus :

            ContextMenu = new RadContextMenu();
            ContextMenu.ItemClick+=new RadRoutedEventHandler(ContextMenu_ItemClick);
            MenuModel menu = new MenuModel();
            MenuItemCollection y=  menu.Items;
            Binding bin = new Binding("Items");
            bin.Source = y;
            ContextMenu.SetBinding(RadContextMenu.ItemsSourceProperty,bin);
            but.SetValue(RadContextMenu.ContextMenuProperty, ContextMenu);

The context menu open empty , ( the binding does not  happen.) and in "menu" object have items.(I exam it in debug).
Why???
Thanks,

Hi ruty,

can you try with:
ContextMenu = new RadContextMenu();
ContextMenu.ItemClick+=new RadRoutedEventHandler(ContextMenu_ItemClick);
// MenuModel menu = new MenuModel();
// MenuItemCollection y= menu.Items;
// Binding bin = new Binding("Items");
// bin.Source = y;
// ContextMenu..SetBinding(RadContextMenu.ItemsSourceProperty,bin);
ContextMenu.ItemsSource = model.Items;
but.SetValue(RadContextMenu.ContextMenuProperty, ContextMenu);

Hello ruty,

Please, send me your project and I will try to fix it for you. To do that you will have to open a new support ticket and attach the file there.
