Private Function BrowserHeight() As Integer

Return HtmlPage.Document.DocumentElement.GetProperty(Of Integer)("clientHeight")

End Function

Private Function BrowserWidth() As Integer

Return HtmlPage.Document.DocumentElement.GetProperty(Of Integer)("clientWidth")

End Function

And it works like a charm... Thank you all for helping me out!

Sopheap Ly:

Have you tried putting those code in the Resize() event yet? You need to do this because the host element width/height is fluid.

txtLoading is still accessible from everywhere. I don't know why you said if you call txtLoading in the Resize(), other parts would not be able to access it.

Hi Sopheap Ly,

Thanks for the reply. What i ment was not that i would not be abel to access txtLoading. Just that i dont want to put all of my code in the Resize() sub.
That i want to be be abel to add text and elements in other sub's / functions and still be abel to get them in correct placement of the screen. Are at work currently but will test some more when i get home. Thanks!

Hello, this is a known issue in the current alpha bits, and has been fixed in Silverlight 2.0 Beta (but may be will introduce some break changes). In the current bits, BrowserHost.ActualWidth/Height will return 0 in the Loaded event. If you want to work around this issue now, you can try this:

Dim screenWidth As Integer = (HtmlPage.Document.DocumentElement.GetProperty(Of Integer)("clientWidth"))

Dim screenHeight As Integer = (HtmlPage.Document.DocumentElement.GetProperty(Of Integer)("clientHeight"))

txtLoading.SetValue(Canvas.LeftProperty, ((screenWidth - test.ActualWidth) / 2))

txtLoading.SetValue(Canvas.TopProperty, ((screenHeight - test.ActualHeight) / 2))

You’ll probably want to wrap these code into a method, because you need to call it both in Loaded and Resize.

But I suggest you to wait for Silverlight 2.0 Beta, because there’s likely to be some break changes. Sorry I can’t provide you with more details at this time…

Sopheap Ly:

Like Bill Reise mentioned before, why don't you just replace with this:

Don't use the _width all the time, because variable stores by value not reference. That means when Interop.BrowserHost.ActualWidth changes, the _width does not. So use Interop.BrowserHost.ActualWidth directly.

Ok so i removed my _width and _height and so now my code looks like this:

Partial Public Class Page

Inherits Canvas

Public Sub Page_Loaded(ByVal o As Object, ByVal e As EventArgs)

' Required to initialize variables

InitializeComponent()

' Add handlers

AddHandler Interop.BrowserHost.Resize, AddressOf Me.BrowserHost_Resize

txtLoading.Text = "Meantime Media"

txtLoading.SetValue(Canvas.TopProperty, (Convert.ToDouble(Interop.BrowserHost.ActualHeight - txtLoading.ActualHeight) / 2))

txtLoading.SetValue(Canvas.LeftProperty, (Convert.ToDouble(Interop.BrowserHost.ActualWidth - txtLoading.ActualWidth) / 2))

txtDebuging.FontSize = 9

txtDebuging.Text = "Width: " + Interop.BrowserHost.ActualWidth.ToString + ", Height: " + Interop.BrowserHost.ActualHeight.ToString

End Sub

Private Sub BrowserHost_Resize(ByVal sender As Object, ByVal e As System.EventArgs)Dim parentCanvas As Canvas = FindName("parentCanvas")

parentCanvas.Width = Interop.BrowserHost.ActualWidth

parentCanvas.Height = Interop.BrowserHost.ActualHeight

End Sub

End Class

But the trubble with Refresh (F5) is still there. Most of the time when i hit Refresh, the value of Interop.BrowserHost.ActualWidth is 0 and the same for
Interop.BrowserHost.ActualHeight. I dont want to place all the code in BrowserHost_Resize, becourse i want to be abel to work with txtLoading etc from other parts in the code aswell.

Bill Reiss:

Yes that's what's happening, you're setting the width and height of the canvas, but then setting the text to the width and height of the page object, which haven't been set, so they will be 0

Any tip on work around for this ?

btw, do you overwrite your new and height-property?

prepend a "MyBase" in front of height/width ... maybe you do smth with height and width ...
