Re: Is there any native WPF Multiselect combobox available ? - WPF Discussion Boards

Message Removed

In the thread above this one, the same situation came up. You will need to use the ItemContainerStyle instead of the ItemTemplate.

Hi,

I am working on an AddIn to the Microsoft Outlook Office. I have added an HTML Folder to Personal folders section in Outlook 2007. When I click on the folder, im redirecting to specified url. When I specify the internet application (both web and silverlight applications), its working fine. But If I specify an intranet silverlight application its not working. Its working for normal intranet web applications.

Please let me know why it is not working for intranet silverlight applications only?

here is the code..

Outlook.MAPIFolder newView = null;
newView = (Outlook.MAPIFolder)inBox.Folders.Add("TUIPoC", Outlook.OlDefaultFolders.olFolderInbox);
newView.WebViewURL = "http://....";
newView.WebViewOn = true;

TUIPoC is the folder name that i have created.

Please help me.

Thanks in Advance,

AR Reddy

How is the Silverlight app hosted? Is it accessible from a regular browser?

i dont know, but you can easyly create it by your own.
create a usercontrol with a grid. add a textbox, a button and
a listbox. listbox height = 0. on button click listbox height = yourvalue.
if you want i can wirte it for you. tell me

My Silverlight play project right now calls for me to use a simple listing of 'things' and display them to the user. Each of these things is going to be a template comprised of an image and two lines of text. One of the lines I need to click on and launch a file...

I was going to play around with a data-bound list box and use a data template, but it really occurred to me that perhaps that is even more than I need because then I need to create an object, stuff data into it in the xaml and data bind to that.

Why not just use a stack panel and inside that stack pan create several nested stack panels for my items. My thought was that I can then simply turn on a scroll bar for the outer stack panel and I would be done. Not elegant but simple for a small non-dynamic list of 10-15 items that doe snot really need to be data-bound as it changes very little, if ever. Using a list box win windows forms I could do this by simply adding list items manually. IN HTML I could mock this up using a set of nested tables and stuff...

What is the simplest way to do this in Silverlight? I'm asking this now with the intent to go home latter today and get back to it having spent some time at it last night (I can't do Dot-net dev on my machine at work (yet)) so I can't play here just now.

Oh, and nope, this is not homework Smile | :)

I wish it was, but it's not...

There's nothing wrong with the StackPanel-in-a-ScrollViewer approach if
that's all you need.

The ListBox and it's ancestor classes

System.Windows.Controls.ItemsControl
    System.Windows.Controls.Primitives.Selector
        System.Windows.Controls.ListBox

are really geared toward working with collections of data items, where
templating can make things much more flexible.

For static elements that don't need to have templates applied dynamically,
a stackpanel works just fine.

I´ve got problem with XamlParseException in WPF application.
I´m parsing XAML file and I ´m catching XamlParseException (if user try to parse bad XAML), but that isn´t working (can´t catch XamlParseException). I´ve got VisualStudio 2008 and .NET Framework 3.5 SP1 installed.

Does somebody know please how to catch that Exception?

my code:

......
object obj;

try 
{ 
   obj = (object)XamlReader.Load(fs); 
} 
catch (XamlParseException) 
{ 
   MessageBox.Show("Error"); 
   return false; 
} 
....

and here is screen of my problem

That happens when trying to parse xaml file that looks like: (I´m trying to parse xaml file from my WPF project)

<Window x:Class="Administration.Video" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        WindowStartupLocation="CenterScreen" 
        SizeToContent="Height" 
        Width="340" 
        Name="This_Color" 
        ResizeMode="CanMinimize" 
        Loaded="This_Color_Loaded">

I have two one dimentional arrays I want to plot versus each other. Its just a basic x versus y plot. Can someone tell me how to create a simple x y plot in WPF using the date stored in two arrays?

You could always get some ideas from this[^] article.

Hi,
I tried to use ApplicationCommands.Paste for a web browser application but it doesn't work. I used this command for window application and it worked. Is there anyone who has an idea to solve this problem. Thanks.

Ok, so I finally understand what User Controls are all about! What?!? Are they serious??? Does microsoft know the sheer power of this concept!

Wow! WPF is really the way to go.

Anyone else feel the joy?

What? And you can do them in Silverlight in a browser cross platform too??

No way.

Yup - take a look into MVVM. You owe it to yourself.

What exactly is that?

MVVM is a design pattern called Model View ViewModel that's made a big hit in the WPF world. User controls form a large part of the way this pattern works. Josh Smith has written a really good introductory article on it in this months MSDN[^] magazine and Karl Shifflett has recently talked about it on Channel 9[^] (you owe it to yourself just to see his Hawaiian shirt).

are they the same? Silverlight - and - "WPF Web Browser App"?

Thanks

No. WPF Web Browser App is an XBAP.

Hello all,
Im working on an ColorPicker user control and have problems registering DependencyPropertys.
I try to register a new DependencyProperty in Visual Studio 2008 and all is working fine so far.
Now i open Expression blend, add an reference to the ColorPicker.dll, and add a new instance to the window.
When i now build the solution i get an exeption:
"the property IsCurrentColor has allready been registerd from _ColorPicker"
and the usercontrol cant anymore viewed in expression blend. Im a little confused because the
application anyway started and all is working. Here is a little code of mine.

public partial class _ColorPicker
   {        
        private readonly DependencyProperty IsCurrentColorProperty;       

        public _ColorPicker()
	{
	        this.InitializeComponent();            

                IsCurrentColorProperty = DependencyProperty.Register(
                "IsCurrentColor", typeof(Color), typeof(_ColorPicker),
                new FrameworkPropertyMetadata(Color.FromRgb(255, 255, 255),
                new PropertyChangedCallback(OnIsCurrentColorChanged)));
        }
        private void OnIsCurrentColorChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
        {
            SetColorInfos((Color)e.NewValue);
            _currentColor.Background = new SolidColorBrush((Color)e.NewValue);
            //RaiseEvent(new RoutedEventArgs(this.iCurrentColorChangedEvent, (Color)e.NewValue));
        }
   }
