Setting BitmapImage.UriSource in a XAML file read with XamlReader [VB][WPF]
-
Hello, My WPF application (WpfApplication1) is, for its XAML part, composed of an single empty grid. Elements are loaded inside this grid from an external XAML file, read through XamlReader. This external Xaml file contains (for the purpose of this example) a URL to an image which should be located in the 'My documents' user folder. The problem is that during importation the url from images should be relative to the application which is loading the file! In other words, this URL should be relative to the application (pack://siteoforigin:, pack://application) ...and in my case, this path is 'outside' from that context and should be built this way: Environment.GetFolderPath(Environment.SpecialFolde r.MyDocuments) & "Theme\" So, I wrote a Converter, hoping to build the complete path url...but without succes!! > 'Impossible to create the unknow type '{clr-namespace:WpfApplication1}imgurlConvert'.' The application XAML part:
The application VB part:
Imports System.IO
Class MainWindow
Public Shared ThemeTempFolder As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) & "\Theme\"
Public Shared themeGrid As Grid
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
Debug.Print(ThemeTempFolder)
loadInterface()
End Sub
Sub loadInterface()
' Load extracted (grid) xaml file as content of the window
Dim GridUri As String = ThemeTempFolder & "theme.xaml"
Dim fs As FileStream = New FileStream(GridUri, FileMode.Open, FileAccess.Read)
Dim sri = TryCast(System.Windows.Markup.XamlReader.Load(fs), Grid)
Me.Content = sri
fs.Close()
' Liens, dans le code, aux ?l?ments de l'interface charg?e en Xaml.
themeGrid = LogicalTreeHelper.FindLogicalNode(sri, "themeGrid")
End Sub
End Class
Public Class imgurlConvert
Implements IValueConverter
Public Function Convert(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements IValueConverter.Convert
