|How does the Silverlight 3 VirtualizingStackPanel work?|
| by Rob Archer in Programming Languages|
What are the actual conditions that make the Silverlight 3
VirtualizingStackPanel virtualise its content?
For example is
it only when elements are off screen regardless of what container it is in
or does the VirtualizingStackPanel have to be in a ScrollViewer before it
starts applying the virtualisation?
I ask this because the MSDN
documentation does not give much inform
|ItemsControl, VirtualizingStackPanel and ScrollViewer height|

The reason why I'm using an ItemsControl is that
the DataTemplate is much more complex in the application I'm working on:
The sample code provided only reflects the sizing problem I have.

| by Neil Redfern in Network & Servers|
I have a
ListBox that may have many rows of templated DB
records, including an
Image, bound to an
ObservableCollection<MyItem>. Sometimes the collection
could hold thousands of items.
The performance is great, but
the scrolling is the default jumpy behavior. I would like it to have
smooth scrolling, so I unchecked
|Get VirtualizingStackPanel non-realized item index|
| by GregoryWE in Programming Languages|
Is it possible to get the index of an item in a WPF
VirtualizingStackPanel that hasn't been realized without directly querying
the ItemsControl's data source? The only thing I can think of is to use
the ItemContainerGenerator but I haven't found anything that returns an
index for an item.
I'm essentially trying to determine if a
specific item is listed before or after the current v

| by Yserbius in Programming Languages|
I have a Listbox displaying 5 items at a time, horizontally. I want to
implement a 'Previous' and 'Next' button that when clicked, will display
the previous set of 5, or next set of 5 items. I am not displaying the
horizontal scroll bar, as I don't want a user to navigate with that.
Is there already some functionality implemented so I can do this, or
do I need to write code to cal
|How to make ListView change ItemControl to VirtualizingStackPanel at runtime|
| by TheVrolok in Development Tools & Services|
OK, so, I have a ListView-derived control that changes Grouping and
ItemsSource on the fly. When I group such that the scrollbars dissapear,
and then change my ItemsSource to a different ICollectionView, my
scrollbars do not return.
The basic problem is that ListView
changes to a VirtualizedStackPanel when grouping is activated and does not
change back when grouping is de-activat
|How to find matching words in Text Box and Datagrid when VirtualizingStackPanel.IsVirtualizing=“true”?|
| by static AG in Development Tools & Services|
I have Datagrid and Text Box in my Form. Datagrid is showing me existing
items in my stock. I use Text Box to search and set focus to that row which
is matching with my Text Box. Now it is working fine when
VirtualizingStackPanel.IsVirtualizing="false" but it is very slow and
getting a lot RAM resource.
Here is my code for this.
