Check the Immediate debugging window when the UserControl is loaded. Are there warnings about not being able to perform a binding because the property Strip cannot be found on object of some type or another? If so, that is referring to the ItemContainerStyle and you should bind to Content.Strip and Content.Panel instead.

As far as the grid, I did pull out two lines when I copied from the previous post because I thought they would not be necessary. Apparently I should have tested that assumption first. The lines I pulled out made each row and column part of a SharedSizeGroup since the grid does not always seem to size * columns the way it seems like it should.

for (int strip = 0; strip < _stripsPerPanel; strip++)
{
    rd = new RowDefinition();
    rd.Height = new GridLength(1, GridUnitType.Star);
    rd.SharedSizeGroup = "RowGroup";
    grd.RowDefinitions.Add(rd);
}

for (int part = 0; part < _partsPerStrip; part++)
{
    cd = new ColumnDefinition();
    cd.Width = new GridLength(1, GridUnitType.Star);
    cd.SharedSizeGroup = "ColumnGroup";
    grd.ColumnDefinitions.Add(cd);
}

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

Accessing silverlight application throw outlook addin

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

Simple listbox stuff

Ray Cassick3-Feb-09 7:22

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.

Can´t catch XamlParseException

Czechtim3-Feb-09 1:01

Czechtim

3-Feb-09 1:01

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" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="Video"  
        WindowStartupLocation="CenterScreen" 
        SizeToContent="Height"

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).
