Please update your bookmarks, because the new url of this blog is http://khason.net/ (you have not update RSS feeds, it will be done automatically). Why I did it? Why I decided to go to “stand-alone”… Well. there are some reasons. Generally, I do not want to explain all those here, but trust me, there are some. The main reason is, that there is no responsible person in charge for this blog platform in Microsoft Israel. This why, if your blog is popular and you have a respect to your blog visitors, you cannot host it here… Take a look into new comments notifications in my inbox. Would you answer your readers with such “small amount” of SPAM and capcha, that cannot be fixed already for three years in this platform? This how my inbox looks like for last three years. So now, you should not ask me, why I not answered your email or comments. Aren’t you? :)

Currently, all comments in this blog are disabled, so if you want to comment, please use new url of posts (this will appear shortly in the beginning of each post). Also, this post will not be syndicated in RSS.

So, this post is the last. I loved this platform, and loved people started it. But, unfortunately, it seemed, that bloggers community is not important enough for new platform managers.

Also, If you want to learn how to use C# and XML-RCP to migrate from CS2007, used in this platform, visit my new home :)

Have a great year and, as always, be good people. This post marked with all possible tags automatically. Sorry.

Quick Silverlight Tip: How to access HTML DOM from Silverlight and Silverlight managed objects from HTML?

After my session yesterday, I got number of email from people, who have a problem to access HTML DOM from Silverlight and vice verse. I want to answer to all of you by this post.

Access HTML from Silverlight

You have not do anything special in Silverlight to access it. Your friend is HtmlPage.Window object. For example, if I want to execute window.open JavaScript method from Silverlight, all I have to do is to call:

public void OpenWindow()

{

HtmlPage.Window.Invoke("open", new object[] { "http://blogs.microsoft.co.il/blogs/tamir", "login", "resizable=1,width=646,height=436" });

}

HtmlPage.Window.Invoke also returns Object – this is the response of function executed.

Access Silverlight Managed Objects from HTML

Here you should remember two things:

You should mark both class and member you want to access with special attributes ScriptableType (for class) and ScriptableMember (for member)
Register Scriptable object anywhere (for example in Constructor).

So, if you want OpenWindow method to be exposed from the Page class to HTML, you should use following code:

    [ScriptableType]
public partial class Page : UserControl    {
public Page() {
            InitializeComponent();
            HtmlPage.RegisterScriptableObject("Page", this);
        }

[ScriptableMember]
public void OpenWindow() {
object o = HtmlPage.Window.Invoke("open", new object[] { "http://blogs.microsoft.co.il/blogs/tamir", "login", "resizable=1,width=646,height=436" });
        }
}

That’s all, folks. Be good people and have a nice day.

Here the script of test application:

Page.xaml

<UserControl x:Class="DomAccessDemo.Page"

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

Height="20">

<Grid x:Name="LayoutRoot" Background="White">

<Button Click="Button_Click" Content="Fun!"/>

</Grid>

</UserControl>

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Browser;

using System.ComponentModel;

namespace DomAccessDemo

{

    [ScriptableType]

public partial class Page : UserControl

    {

public Page()

        {

            InitializeComponent();

HtmlPage.RegisterScriptableObject("Page", this);

        }

private void Button_Click(object sender, RoutedEventArgs e)

        {

            OpenWindow();

        }

        [ScriptableMember]

public void OpenWindow()

        {

object o = HtmlPage.Window.Invoke("open", new object[] { "http://blogs.microsoft.co.il/blogs/tamir", "login", "resizable=1,width=646,height=436" });

        }

    }

}

DomAccessDemoTestPage.aspx

        {

var xaml = document.getElementById("Xaml1");

            xaml.Content.Page.OpenWindow();

        }

</script>
