Focus on first element in listbox

Question

I am facing the following issue. When i am removing the first element from a list box which has keyboard focus(by refreshing the item source) the keyboard focus is moving to the parent window. I want to retain the keyboard focus on the fist listbox item. So i came up with the following code

<Grid.Resources>
<Style TargetType="{x:Type ListBox}">
    <Style.Triggers>
        <DataTrigger Binding="{Binding FirstRowDeleted}" Value="True">
            <Setter Property="FocusManager.FocusedElement" Value="{Binding ElementName=MyListBox}" />
        </DataTrigger>
    </Style.Triggers>
</Style>

Using this code i am able to move the focus to the list box itself. How can i move the focus to the first listbox item? MyListBox[0] does not seem to work. Any suggestions?

Thanking you Kaddy

Value="{Binding ElementName=FavoriteResultListBox.Items[0]}" or Value="{Binding FavoriteResultListBox.Items[0]}" is not working — Kaddy, Sep 01 '16 at 17:59
My bad, try `Value="{Binding Path=Items[0], ElementName=FavoriteResultListBox}"` — 15ee8f99-57ff-4f92-890c-b56153, Sep 01 '16 at 18:00
What's the listbox really called? You keep changing your story. Please show enough of your XAML so I can see both the listbox and the Style you have in your question now. — 15ee8f99-57ff-4f92-890c-b56153, Sep 01 '16 at 18:10

I don't have time to pull teeth like this. I have no way of knowing if those two decontextualized snippets are even in the same file. — 15ee8f99-57ff-4f92-890c-b56153, Sep 01 '16 at 18:21

I found answer here: How do you programmatically set focus to the SelectedItem in a WPF ListBox that already has focus?

var listBoxItem = (ListBoxItem) MainListBox
    .ItemContainerGenerator
    .ContainerFromItem(MainListBox.SelectedItem);
listBoxItem.Focus();

Thanks for @Jeff for the answer.

This code applies the focus function to the first input text when the page loads. try it out

$(document).ready(function () {

                $("#input:text:visible:first").focus();


            });
