Open Xaml Page From String

Hi
Add in the tab a web control and set the web.navigate to the XML content
An example of adding a tab and a web control on the tab below:-

Dim oTab As New TabPage
oTab.Name = "NewTab" 
oTab.Text = "NewTab"
oTab.Parent = Me.TabControl1 ' Your Tab Control name
Me.Controls.Add(oTab)
webReport.Parent = oTab
webReport.Dock = DockStyle.Fill
webReport.Navigate(sXMLContent)

xXMLContent is the XML data

Select allOpen in new window

This code looks like winforms and not silverlight. I am building a silverlight page and loading xaml not xml

In order to create a control graph from a XAML string, I would look at the XamlReader class, which is in the System.Windows.Markup namespace.

XamlReader Class

' Load the button
Dim stringReader As New StringReader(savedButton)
Dim xmlReader As XmlReader = XmlReader.Create(stringReader)
Dim readerLoadButton As Button = CType(XamlReader.Load(xmlReader), Button)

Select allOpen in new window

Sorry , i didnt realize, I never realized as there is a tag for Visual Basic .NET also

Are you talking about the Silverlight TabControl, and you have created the TabItem but want to add your xaml "page" as a child to that tab Item?

Assuming that this is what you are trying to do, I think this code snippet might help.  Let me know if it you are trying to do something different.

Dim tItem As New TabItem

tItem.Content = New MyXamlPage

Select allOpen in new window

vbigham that is excatly what I wanted regarding the content. Thank you. The only part of the question left is how can I sent the xaml page to use a string passed in somewhat like the example below

sub opennewpage (pagename as string)

Dim tItem As New TabItem
tItem.Content = New pagename 

end sub

Select allOpen in new window

combining TheLearnedOne post above and yours we get

sub opennewpage (pagename as string)

Dim stringReader As New StringReader(pagename )
Dim xmlReader As XmlReader = XmlReader.Create(stringReader)
Dim tItem As New TabItem
tItem.Content = CType(XamlReader.Load(xmlReader), UIElement)

end sub

Select allOpen in new window

but using that method it will not bring the backend code and everything else over from the silverlight page. In my winforms app i did the following

Dim obhNew As Runtime.Remoting.ObjectHandle
obhNew = Activator.CreateInstance(Nothing, pagename)
Dim frmNew As Form = DirectCast(obhNew.Unwrap, Form)

Select allOpen in new window

If you don't have too many pages I would be inclined to Select Case based on the page name string, and load the appropriate one.  If you are building these pages on the fly, then that is when you would probably need a xamlReader, and wiring up all the code/event handlers sounds interesting.

Here is what I would do, as long as you are building these pages at design time:

Sub opennewpage(ByVal pagename As String)
        Dim tItem As New TabItem

        Select Case pagename.Trim.ToLower()
            Case "page1.xaml", "page1"
                tItem.Content = New Page1

            Case "page2.xaml", "page2"
                tItem.Content = New Page2

            Case "page3.xaml", "page3"
                tItem.Content = New Page3

            Case "page4.xaml", "page4"
                tItem.Content = New Page4

            Case Else
                Throw New Exception("Invalid Page Request: " & pagename & " cannot be found")
        End Select
    End Sub

Select allOpen in new window

That is what I have done in the current situation but this app can have over 100 pages.

That worked perfect. That was excatly what I needed. Thank you for all of your help.
