I got VirtualQueryableCollectionView working with RadComboBox when VirtualizingStackPanel is used.
However, when filtering is enabled, the ComboBox would load all the items (batched in LoadSize) from the VirtualQueryableCollectionView before displaying the dropdown. Am I missing something here?
The combobox Xaml:

Is it possible to add support for VirtualQueryableCollectionView?
In the software that I am working on, the data source contains hundreds of thousands records via WCF data service (OData), and it would take forever to load if the list had to be populated fully before AutoCompleteBox can search.

Hi,
we're not happy with the gradient in Blue Theme of RadOutlookbar. So we want to have no gradient in the ItemTemplate of the OutlookBar.
Bright icons are hard to see clearly.
How can i edit the gradient of the ItemTemplate.
I tried to set a new ItemTemplate, but it stays gradient like in the skin.
Best regards,
David

If you take a look at the Demo of PanelBar (http://demos.telerik.com/silverlight/#PanelBar/FirstLook) that is essentially what I want, but with the added functionality of collapsing the entire PanelBar to Left and information on the right expanding to the left. With just a button or something to re-expand the menu.
Apologies if there was a more appropriate area to post this, as this was my best guess.

Hi,
I am attempting to recreate the print and export example for WPF in my code. I have the PrintAndExportWithRadDocumentModel and Commands, and in my XAML I have
<Window.Resources>
<local:PrintAndExportWithRadDocumentModel x:Key="context" />
</Window.Resources>
and
However, when I click on the button I get a null object parameter in the Print method (in the PrintAndExportWithRadDocumentModel class). My question is, how do I bind the RadGridView to the button click so it gets passed as the parameter?

I have a problem with my TreeListView not responding the INotifyCollectionChanged events immediately.
When a user requests to change the order of a node, my code will remove and then reinsert all of the children of the node into a different position with a different display name. But the tree list view still displays the children in the old order and with the old name. If I expand some unrelated node, the children will change to the new order and the new display names.
Is there a way to get the tree list view change immediately?
My ItemsSource is an IQuerable against an ObservableCollection. It looks like this:

I have a set of tabbed views that correspond to RadTreeViewItems so that when the treeViewItem is clicked, the correct tab is selected and when a different tab is clicked, the correct treeViewItem is selected. I am binding to the RadTreeViewItem.Command property so that I am notified when the user clicks on the treeViewItem..
The problem is that programmatically changing the IsSelected property of a treeViewItem does not "reset the active" treeViewItem, meaning that the original treeVIewItem will not fire its Command when the user clicks on it. Visually, everything looks correct, but I don't know how to notify the treeview that I programmatically changed the active treeViewItem.
Example, the user clicks on treeViewItem1 --> treeViewItem1 highlights and then highlights tab1. The user then selects tab2 --> tab2 highlights and treeViewItem2.IsSelected is set to true. When the user clicks back on treeViewItem1, its Command is not fired.
Additionally, I do not want the treeViewItem that is programmatically set as IsSelected to fire its Command. That would cause in infinite loop in my current code.

Hi,
We created a custom column (based on GridViewBoundColumnBase using the CreateCell* methods to create the various controls) to display a TextBox and a RadButton. The purpose of the button is to show a modal window to display the content of the TextBox (because our TextBox cannot not accept multilines).
Here an example of what we're doing:
| SSN | Another column | My Custom column |
--------------------------------------------------------------
| | | *Text Box* |Button| <----- New Row
--------------------------------------------------------------
| 111111111 | | *Text Box* |Button|
--------------------------------------------------------------
There is a validation on the mandatory SSN column.
First implementation
Both the Cell and cell edit template define the button with IsEnabled = true.

--------------------------------------------------------------
| 111111111 | | *Text Box* |Button|
--------------------------------------------------------------
There is a validation on the mandatory SSN column.
First implementation
Both the Cell and cell edit template define the button with IsEnabled = true.
- When we click on the button on row #2, the Click Event of the button is triggerred (showing our modal window). Then, the row validating of the first row is fired. This leaves us in a bizarre situation where our modal shows info from the second row while the grid marks the first row with validation errors.
Second implementation
The button in the Cell Template is IsEnabled = False and the one in the CellEdit is IsEnabled=true.
In this scenario, when we click on the disabled button on row #2, the validation of row #1 is triggered. The focus on row #2 is set only when row #1 is valid.
However, on row #2 when the Cell Edit template is shown, the focus is set to the first control (Textbox)...
In the second approach, there are 2 problems: 1 - The "click" is not sent to the "Cell Edit" button AND 2 - the "Cell" button is disabled (at first, the user thinks that the button is not accessible.
--------------------------------------------
With that in mind, is there a way to this :
- In the first implementation, is there a way to trigger Validation of the first row within our Custom column and giving back the focus on row #1;
- In the second implementation, is there a way to visually make the the RadButton looks like an Enabled button event when disabled AND is there a way to catch the click on the disabled button and to trigger it on the enabled button;
- A new and better implementation ;-)
Thanks.
