How to change string text in xaml

Question

I have string text in ListPickerItem like this
<toolkit:ListPicker x:Name="items" FullModeHeader="Items" Background="White" Margin="10,280,14,0" VerticalAlignment="Top" Foreground="Black" FontSize="25.333">
<toolkit:ListPicker.Header>
<TextBlock x:Name="Choose_Items" Opacity="0.8" Text="Choose Items" Foreground="White"/>
</toolkit:ListPicker.Header>
<corelib:String>item1</corelib:String>
<corelib:String>item2</corelib:String>
<corelib:String>item3</corelib:String>
<corelib:String>item4</corelib:String>
<corelib:String>item5</corelib:String>
<corelib:String>item6</corelib:String>
<corelib:String>item7</corelib:String>
<corelib:String>item8</corelib:String>
</toolkit:ListPicker>
So in code I want to change this text by the resource each string have another value like this
And the code is
Public Shared Iterator Function FindVisualChildren(ByVal obj As DependencyObject) As IEnumerable(Of DependencyObject)
If obj IsNot Nothing Then
For i As Integer = 0 To VisualTreeHelper.GetChildrenCount(obj) - 1
Dim child As DependencyObject = VisualTreeHelper.GetChild(obj, i)
If child IsNot Nothing Then
Yield child
End If
For Each subChild In FindVisualChildren(child)
Yield subChild
Next
Next
End If
End Function
Private Sub Change()
Dim rm As New ResourceManager("App.Resource1", GetType(MainPage).Assembly)
Dim main As Grid = ContentPanel
Dim result = FindVisualChildren(main)
Dim ST = result.OfType(Of String)()
For Each item In ST
item = rm.GetString(item.Text)
Next
End Sub
So How I can make right code to run like this problem ??
Thanks :)

Hi Shay Boshra,
Based on your description, it seems that you want to change the ListPickerItem content based on the resource file, if I do not misunderstand you, an easy way to implement it is that first you can define the ListPicker as following:
In the MainPage.xaml:
<toolkit:ListPicker x:Name="items" Background="White" Margin="0,-11,24,0" VerticalAlignment="Top" Foreground="Black" FontSize="25.333">
<toolkit:ListPicker.Header>
<TextBlock x:Name="Choose_Items" Opacity="0.8" Text="Choose Items" Foreground="White"/>
</toolkit:ListPicker.Header>
<toolkit:ListPickerItem Content="item1"></toolkit:ListPickerItem>
<toolkit:ListPickerItem Content="item2"></toolkit:ListPickerItem>
<toolkit:ListPickerItem Content="item3"></toolkit:ListPickerItem>
<toolkit:ListPickerItem Content="item4"></toolkit:ListPickerItem>
<toolkit:ListPickerItem Content="item5"></toolkit:ListPickerItem>
</toolkit:ListPicker>
<Button Content="Change Text" HorizontalAlignment="Left" Margin="20,446,0,0" VerticalAlignment="Top" Click="Button_Click" Width="299"/>
In the MainPage.xaml.cs:
Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
Dim ResourceManager As New ResourceManager("App.Resource1", GetType(MainPage).Assembly)
For Each listpickitem As ListPickerItem In items.Items
listpickitem.Content = ResourceManager.GetString(listpickitem.Content.ToString())
Next
End Sub
The result:
