Answer 1

Page.Template.FindName() method can do the trick.

Answer 2

Hello,

i`ve tried this:

Dim obj As Object = Template.FindName("backGrid", Me)

   If obj Is Nothing Then

      Console.WriteLine("null")

   Else

       Console.WriteLine(obj.ToString)

   End If

 

Thats don't work. The Function returns nothing.

Answer 3

Does the control template you create for the page really get applied to the Page?

Answer 4

Hello,

here my code in page:

<Page x:Class="Page2"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="bilder" Style="{StaticResource DefaultLayout}" ShowsNavigationUI="False"

>

</Page>

 

Code Behind:

Partial Public Class Page2

Inherits System.Windows.Controls.Page

Dim LayoutData As DefaultLayoutData

Public Sub New()

InitializeComponent()

Dim o As ObjectDataProvider

o = Me.Style.Resources("LayoutData")

LayoutData = o.Data

LayoutData.CurrentDescription = "current description"

LayoutData.CurrentItem = "currentitem"

LayoutData.PageSubTitle = "subtitle"

 

Dim obj As Object = Template.FindName("backGrid", Me)

   If obj Is Nothing Then

      Console.WriteLine("null")

   Else

       Console.WriteLine(obj.ToString)

   End If

End Sub

End Class

Thats all. I can see all controls where i defined in the Style "DefaultLayout".

I hope you mean this...my english...
