I am trying to open HTML file in WebBrowser window of WPF using MVVM patten.
Note: I have fixed the issues i was getting. Now this code works as desired.
ViewHTMLPageView.xaml
<Window x:Class="MyProject.ViewHTMLPageView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<Grid Name="grid1">
<WebBrowser local:WebBrowserUtility.BindableSource="{Binding ReportPage}" />
</Grid>
</Window>
ViewHTMLPageViewModel.cs
namespace MyProject
{
public class ViewHTMLPageViewModel: ViewModelBase
{
public ViewHTMLPageView()
{
//Testing html page on load
_reportPage = "<table border='5'><tr><td> This is sample <b> bold </b></td></tr></table>";
OnPropertyChanged("ReportPage");
}
private string _reportPage;
public string ReportPage
{
get
{
return _reportPage;
}
set
{
if (_reportPage != value)
{
_reportPage = value;
OnPropertyChanged("ReportPage");
}
}
}
}
WebBrowserUtility.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Controls;
using System.Windows;
namespace MyProject.Utility
{
public static class WebBrowserUtility
{
public static readonly DependencyProperty BindableSourceProperty =
DependencyProperty.RegisterAttached("BindableSource", typeof(string),
typeof(WebBrowserUtility), new UIPropertyMetadata(null,
BindableSourcePropertyChanged));
public static string GetBindableSource(DependencyObject obj)
{
return (string)obj.GetValue(BindableSourceProperty);
}
public static void SetBindableSource(DependencyObject obj, string value)
{
obj.SetValue(BindableSourceProperty, value);
}
public static void BindableSourcePropertyChanged(DependencyObject o,
DependencyPropertyChangedEventArgs e)
{
var webBrowser = (WebBrowser)o;
webBrowser.NavigateToString((string)e.NewValue);
}
}
}

In WebBrowserUtility.cs, change the following statement:
using System.Windows.Forms;
to
using System.Windows.Controls;
Now, for +1 on your question, can you tell me why this fixes your problem?
