I am trying to provide a UserControl that wrappers up the WebBrowser control and provides the additional events raised on the DWebBrowserEvents_Event and DWebBrowserEvents2_Event interfaces.
I have a class that works fine when only one extended browser control is in the xaml hwever when I have 2 the second one works but the first is failing to show the page its pointed at.
The user control code is as follows
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
namespace CustomControls
{
public partial class ExtWebBrowser : UserControl
{
private static WebBrowser baseBrowser;
private SHDocVw.DWebBrowserEvents_Event wbEvents;
private SHDocVw.DWebBrowserEvents2_Event wbEvents2;
private SHDocVw.IWebBrowser2 myWebBrowser2;
static ExtWebBrowser()
{
DefaultStyleKeyProperty.OverrideMetadata(typeof(ExtWebBrowser), new FrameworkPropertyMetadata(typeof(ExtWebBrowser)));
}
public ExtWebBrowser()
{
}
#region Dependency Properties
#region UrlProperty
public Uri Url
{
get {
return (Uri)GetValue(UrlProperty);

set {

}
}
public static readonly DependencyProperty UrlProperty =
DependencyProperty.Register("Url", typeof(Uri), typeof(ExtWebBrowser), new UIPropertyMetadata(new Uri("about:blank"), UrlChanged));
private static void UrlChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
if (baseBrowser != null)
{
baseBrowser.Source = e.NewValue as Uri;
}
}
#endregion
#region ScriptingObjectProperty

baseBrowser.LoadCompleted += new LoadCompletedEventHandler(baseBrowser_LoadCompleted);
baseBrowser.ObjectForScripting = ScriptingObject;
baseBrowser.Source = new Uri("about:blank");
}
}

}

internal interface IServiceProvider
{

object QueryService(ref Guid guidService, ref Guid riid);
}
}
The xaml is as follows
<Window x:Class="UCA.ChordiantWindow"

<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type custom:ExtWebBrowser}">

BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<Grid>
<Button>Hello</Button>

</Grid>
</Border>

</Setter>
</Style>
</Window.Resources>
<Grid>
<StackPanel>
<custom:ExtWebBrowser Url="http://www.amazon.co.uk" />
<custom:ExtWebBrowser Url="http://www.microsoft.com" />
</StackPanel>
</Grid>
</Window>
What have I got wrong?
EDIT
Thought it might be the dreaded WebBrowser control itself however the page works if I use to Webrowser contols rather than the extended one.
Also It looks like the Url DP gets shared as another page with the control in seems to change its content in-line with changes to the window?

There's your problem - your control is only ever using a single instance of the WebBrowser control, no matter how many instances of your control you create.
It looks like the only reason you've made it static is so that you can access it from the DependencyPropertyChanged events. All you need to do is cast the DependencyObject parameter to your ExtWebBrowser class, and you'll be able to access non-static fields, properties, and methods.

Thanks for that  Think I got a little code blind!
Changed the
private static WebBrowser baseBrowser;
to
internal WebBrowser baseBrowser;
and the Onchanged events to
private static void UrlChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
ExtWebBrowser ext = o as ExtWebBrowser;
if (ext != null)
{
ext.baseBrowser.Source = e.NewValue as Uri;
}
}
private static void ScriptingObjectChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
ExtWebBrowser ext = o as ExtWebBrowser;
if (ext != null)
{
ext.baseBrowser.ObjectForScripting = e.NewValue;
}
}
It all works fine.
Thanks again

Hi there i have recently decided that i wanted to start playing around with app development. I was woundering if anyone can point me to any good information sources for such task. I dont know any xaml or silverlight so im learning from the ground up. Any books you can recommened, web sites, anything really.

I want a StackPanel to be populated by one button for each entry in an ArrayList. I can set up these buttons from the ArrayList using a foreach sequence. But how would I define the corresponding event handlers?

Each button calls the same event (Command) and passes in the commandparameter which should be bound to the object in the collection. So the method receives and object that can then be cast as the item in the collection.

Button btn = new Button();
btn.Click += new RoutedEventHandler( button_Click );

void button_Click( object sender, RoutedEventArgs e ) {
Button btn = sender as Button;

I'm struggling to get my MVVM WPF app to work with a set of Tasks updating the UI.
I've got a Command that starts X number of tasks off, for each task I'd like the UI to update when started and when finished. I've also got a second Command to cancel the task, which I'd obviously like working (the code does but as the UI locks the button doesn't)
I've used a ListBox bound to an ObvservableCollection<string> for the results, as this seemed better than binding to a string.
At the moment I get the UI lockup until all tasks are finished. This is with or without a Task.WaitAll. The results are correct, the tasks don't always start/finish in the same order so they're obviously being generated and updating the collection asynchronously.
I've tried an AysncObservableCollection (as per this SO answer)
I've tried using the Dispatcher in my method that adds a item to the collection.
I've tried variations on the Binding parameters.
Can someone give me some hints  Surely people have created a status log with async stuff in MVVM before??
Do I need to move the task creation to the Model?
I've seen mention of making sure the Collection is initiated on/by the View, not sure I understand that!
The View has a DataContext that's set to my ViewModel. Do they mean I've got to create the Collection in the code behind of the View? that doesn't seem right.
Oh this is .NET4.0 on XP, and I'm not using any MVVM frameworks (didn't think that was a good idea as I'm still learning)

How are you binding the ListBox and ObservableCollection<string>?
Are you creating the ObservableCollection in the ViewModel?
Is it bound to the ItemsSource on the ListBox?
If you can show some of the code/xaml we can provide more assistance.

Ok,
In my view XAML I think the only relevant bits are:
<UserControl.DataContext>
<local:ViewModelLoadTest />
</UserControl.DataContext>
<Button Height="32"
Width="128"
Margin="5"
Content="Run Test"
Command="{Binding RunTestCommand}"/>
<ListBox ScrollViewer.VerticalScrollBarVisibility="Visible"
FontFamily="Consolas"
FontSize="12"
ItemsSource="{Binding Path=Results}">
</ListBox>
I've tried some of the Binding options like Async.
There's nothing in the .xaml.cs file apart from the initialize call. Oh and its in a UserControl because my app has two modes so I'm using a tab control displaying two UserControls.
For my ViewModel, I've got an abstract base ViewModel then a design time and run time classes.
All the child classes do is set some properties, there's no other methods or additional properties.
In the base ViewModel class the collection is defined:
private ObservableCollection<string> _results = new ObservableCollection<string>();
public ObservableCollection<string> Results
{
get { return _results; }
set
{
_results = value;
RaisePropertyChanged("Results");
}
}
I've tried the creation of the collection in the constructor of the BaseViewModel and in the constructors of the child classes.
And in case its my Task stuff that's wrong:
private void DoRunTestCommand()
{
_cancellationTokenSource = new CancellationTokenSource();
Log(String.Format("Submitting {0} requests, every {1}ms, {2} at time."
, Model.NumberOfRequests
, Model.MSBetweenRequests
, Model.NumberOfConcurrentRequests));
CancellationToken cancellationToken = _cancellationTokenSource.Token;
Task[] tasks = new Task[Model.NumberOfRequests];
for (int i = 0; i < Model.NumberOfRequests; i++)
{
int idx = i;
Task r = Task.Factory.StartNew((state) =>
{
SubmitRequest((int) state);
cancellationToken.ThrowIfCancellationRequested();
}
, i
, cancellationToken
, TaskCreationOptions.LongRunning
, TaskScheduler.FromCurrentSynchronizationContext());
tasks[i] = r;
Thread.Sleep(Model.MSBetweenRequests);
}
Log("Done");
}
private void SubmitRequest(int reqNum)
{
Log(String.Format("{0} Started", reqNum));
Thread.Sleep(1000);
Log(String.Format("{0} Finished", reqNum));
}
private void Log(string text)
{
Results.Add(String.Format("{0}: {1}", DateTime.Now, text));
}
Obviously SubmitRequest will do something else, I was just trying to get the UI working before I put the exact details in.

Solved it I think.
I mentioned that I was trying the AsyncObservableCollection, apparently if I use that then I don't want to pass TaskScheduler.FromCurrentSynchronizationContext() to the task. I don't understand why (I guess a conflict somewhere)...but not sure if I need to understand either
So my ObservableCollection is now defined as:
private ObservableCollection<string> _results = new AsyncObservableCollection<string>();
public ObservableCollection<string> Results
{
get { return _results; }
set
{
_results = value;
RaisePropertyChanged("Results");
}
}
And my tasks updated the ListBox as and when they start/finish.
So I've just got to check if cancellation works, and see if I can still use WaitAll. Ideally I'd like a message when the tasks have all been started and finished (more a WhenAll (if that even exists)), at the moment I get that in the middle. But if I use WaitAll then I don't get the async updating.
Note for any others if your using .NET 4.5 then I don't think any of this is an issue as they changed the ObversableCollection.

Using TaskScheduler.Default or TaskScheduler.Current work when using the AsyncObservableCollection, its just FromCurrentSynchronizationContext that doesn't.
|
|
|
|
|
Use the INotifyPropertyChanged event on the observable collection.
This will be a neater and simpler solution.
|
|
|
|

How do you mean? The ViewModel already had that, and that on its own didn't work. No items were added until the end.
private ObservableCollection<string> _results = new ObservableCollection<string>();
public ObservableCollection<string> Results
{
get { return _results; }
set
{
_results = value;
RaisePropertyChanged("Results");
}
}
Or do you mean create a class that derives from ObservableCollection and implement it there?

Please Help me
How can i get the listview item one by one from the
selected row in WPF?
|
|
|
|
|
You could check the lstSomething.SelectedItems it should give you all the selected items. Then use a for each or iterate through the collection.

i have created a control template for flashing button
<ControlTemplate x:Key="buttonTemplate" TargetType="{x:Type Button}">
<Border x:Name="AnimatedColorButton" Width="100" Height="30" BorderThickness="2" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}">
<Border.Triggers>
<EventTrigger RoutedEvent="Border.Loaded"> <BeginStoryboard><pre lang="text">
<Storyboard >
<DoubleAnimation Storyboard.TargetName="AnimatedColorButton" Storyboard.TargetProperty="Background.Opacity"
RepeatBehavior="Forever"
AutoReverse="True"
To="0.0"
Duration="0:0:0.5" ></DoubleAnimation>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Border.Triggers>
</Border>
</ControlTemplate>
Its displays the button with Flashing while loading.
But when i Change the border color from code behind
button1.BorderBrush = Brushes.Blue;
Then the a flashing stops .
How to active it again ?how to trigger the border.loaded event from code behind ?

Hi All, i am attaching my class design and the xaml code which i am using to create a treeview item with circular reference. I am able to update the collecitons from the codebehind but unfortuntely it is not reflecting in the code behind. Please help me in esolving this

Hello,
I want to add dynamically many controls to a window.
I wanted to use a stack panel container but a stack panel has either horizontal or vertical orientation.
I want to add the control horizontally and when there are three user controls in one row i want to go to next row and start adding the controls there and so on.
The user can also delete a control so the other controls have to be reorganized automatically.
Any one has an idea how to do it?
Thanks.
