WPF: complex tab focus behavior

My control is constructed from nested list boxes and tree views. Each list box / tree view item also contains rich text boxes and other controls.

I 开发者_如何学运维want to define a 'tab' focus behavior such that when the user clicks 'Tab' the next focusable item (according to an order i define) will become focused.

Currently it doesn't work as i accept (it only works partially).

My question is not specific to my case - rather on how to define such behavior at all. As an extreme example, let's say i want to completely control this and make the focus jump between items not physically near.

Anyone might know how this can be controlled?

Joe, this mechanism is smarter than i thought, check this nesting - it works perfectly:

<ListBox KeyboardNavigation.TabNavigation="Continue">
    <ListBoxItem Focusable="False">
        <ListBox KeyboardNavigation.TabNavigation="Continue">
            <ListBox.Items>
                <ListBoxItem Focusable="False">
                    <TextBox Width="300" KeyboardNavigation.TabIndex="1" Focusable="True"/>
                </ListBoxItem>
                <ListBoxItem Focusable="False">
                    <TextBox Width="300" KeyboardNavigation.TabIndex="2" Focusable="True"/>
                </ListBoxItem>
                <ListBoxItem Focusable="False">
                    <TextBox Width="300" KeyboardNavigation.TabIndex="3" Focusable="True"/>
                </ListBoxItem>

Are you looking for the KeyboardNavigation.TabIndex property?
