list picker issue in windows phone value hidden

Question

I have a dropdown menu and a ListPicker with two values: A and B. When I select something from the menu, my values appear. When I select a value, it appears in a textbox (A or B). If I click to top of value A, the value dissapears, why?

This is what I have in XAML:

  <toolkit:ListPicker x:Name="Select" Visibility="Collapsed" >
                            <toolkit:ListPickerItem Content="A"/>
                            <toolkit:ListPickerItem Content="B"/>
   </toolkit:ListPicker>

In the code, the ListPicker is set to visibile, TextBox gets the selected value and shows the content.

I've made a video to explain this issue. Any solution? Thanks!

I think that might help you

<TextBox x:Name="myTextBox" Text="{Binding}"/>

<toolkit:ListPicker x:Name="Select" Visibility="Collapsed" SelectionChanged="Select_SelectionChanged">
                        <toolkit:ListPickerItem Content="A"/>
                        <toolkit:ListPickerItem Content="B"/>

Then write the following c# code on the SelectionChanged Event Handler for the listpicker.

private void Select_SelectionChanged()
{
    myTextBox.DataContext = ((ListPickerItem)Select.SelectedItem).Content.ToString();
}

or if if refuses try this one out

private void Select_SelectionChanged()
{
    myTextBox.DataContext = Select.SelectedValue.ToString();
}
