[OzSilverlight] SL Combobox problem.?
Hi All,
I have a Combobox in SL App when I remove item from the collection
(ObservableCollectionUserDTO/List UserDTO ) work fine, but the issue
that Combobox not update its items-Containing area when its bind with
ObservableCollection, mean if there were 4 items in Combobox then will
remain 3 but total space of items-Containing remain 4. And but when its bind
to List then it only delete the item from collection but not from Combobox
area, mean if there were 4 items in Combobox then will remain even 4.
why, here is some code:
XAML:
ComboBox x:Name=ddlUser Canvas.ZIndex=2 Grid.Row=0 Grid.Column=1
DisplayMemberPath=name
ToolTipService.ToolTip=Select user.
Style={StaticResource NormalDropDownListStyle} /
CS:
private ObservableCollectionUserDTO resultUserDTO = new
ObservableCollectionUserDTO();
private ListUserDTO resultUserDTO = new ListUserDTO();
also why should I use List over ObservableCollection.?
Enen though I call this like,
ddlUser.UpdateLayout();
ddlUser.SelectedItem = innerUserDTO;
Thanks Regards,
Muhammad Niaz

Re: [OzSilverlight] SL Fonts.?
It can be done in WPF but the same class doesn't seem to exist in Silverlight
eg. Here is an example
Window.Resources
DataTemplate x:Key=FontTemplate
StackPanel Orientation=Horizontal
Border BorderThickness=1 BorderBrush=Black Margin=10
TextBlock FontFamily={Binding Source}
Text=Sample Text Margin=5 /
/Border
TextBlock Text={Binding Source} VerticalAlignment=Center /
/StackPanel
/DataTemplate
/Window.Resources
ListBox x:Name=fonts ItemTemplate={StaticResource FontTemplate} /
And in code :
fonts.ItemsSource = System.Windows.Media.Fonts.SystemFontFamilies;

RE: [OzSilverlight] SL Fonts.?
Muhammad,
I'm not sure you could get that info directly from SL, but you can look for the
appropriate function in JS and call it from SL.
If you depend on a certain font you can include them in a zip file and get them
through a request and create a FontSource object using the stream. This is part
of SL docs
Downloading Fonts
Silverlight does not include any fonts in its installation package. If you want
to use a font for a TextBlock or TextBox element that is not on the list of
supported local fonts, you can specify the font in XAML by using the FontFamily
property, or in code using the FontSource property. The FontFamily property can
specify a single font file or a zip file containing font files. In either case,
the file must be embedded in a DLL as a resource. When using FontSource, your
code can load the font (or zip of fonts) from a stream such as isolated
storage.

RE: [OzSilverlight] SL Combobox problem.?
The ObservableCollection (or any collection that implements
ICollectionChange) exposes an event (CollectionChanged) and the Databinding
will subscribe to this to monitor changes in the collection, when one occur
it will cause the control to refresh it's datasource.
This is similar to objects that implement INotifyPropertyChange, those will
expose a PropertyChanged event that will trigger an update in the UI
whenever the control value of the property changed (or more precisely when
the event is fired)

Re: [OzSilverlight] SL Error.?
Remarks ArgumentOutOfRangeException is thrown when a method is invoked and at least one of the arguments passed to the method is not nullNothingnullptra null reference (Nothing in Visual Basic) and does not contain a valid value. ArgumentOutOfRangeException is used extensively by: - Classes in the System.Collections and System.IO namespaces. - The Array class. ArgumentOutOfRangeException behaves identically to ArgumentException. It is provided so that application code can differentiate between exceptionscaused by invalid arguments that are not nullNothingnullptra null reference (Nothing in Visual Basic), and exceptions caused by null arguments. For errors caused by null arguments, see ArgumentNullException. For a list of initial property values for an instance of ArgumentOutOfRangeException, see the ArgumentOutOfRangeExceptionconstructors.
