Stop scrolling left when first item is in the centre (topmost)

Hi,

I want the carousel to stop scrolling left when the first item is in the centre of the screen (the topmost item).
I also want the carousel to stop scrolling right when the last item is in the centre of the screen (the topmost item).

Currently, you can continue scrolling left/right until the first or last item is on the extreme left or right of the screen.

Is there anyway to do this?

Also, is there anyway of setting the carousel to wrap around when you come to the end of the items?

Thanks

Retrieve data in code behind from wpf radGrid binded with Multiple collections

Hello!
In my application I'm trying to get data from a RadGridView in my code behind. Everything is ok if I bind the grid directly from entity data model with just a table, because this code works fine:

Example:

Dim idordine As String = DirectCast(testGrid.SelectedItem, Orders).OrderID

In my application I binded my grid with a linq query and my testgrid(radgrid) correctly shows results.
This is a linq query like the one in my project, used to bind my radgrid:

Dim query = From employee In employees Join order In orders On employee.EmployeeID = order.EmployeeID

Select New With { _

.EmployeeName = employee.LastName, _

.OrderName = order.ShipName, _

.OrderDate = order.OrderDate _

}

testGrid.ItemsSource = query

Me.Griglia.ItemsSource = qry

My problem raises in code behind when I try to retrieve data of the selected row of my testgrid after a double-click event.
Using the first method I have to assign a type for the directcast, but in case of binding with the query I have no idea of what kind of object to put instead of Orders type.

Any suggestion?

BestRegards

Y axis values on radCartesianChart with zoom

Hi,

Is there an option to use RadCartesianChart with zoom capability on the X axis in a way that when the zoom/pan had changed the Y axis will fit its min and max values automatically?

If not, How can I get which parts of the series is visible on the chart, so I can calculate Y values by myself?

Thanks.

I can drag but not drop

Dear all,

I want to drag items from one listbox to another. The drag seems to work fine, but the target listbox doesn't get updated with the new item. I do notice that, once dropped, the item is removed from the source list. I try to do stuff declaratively (XAML) as much as I can

Here's the XAML for the enabling of dragging.

<Window.Resources>

<local:ViewModel x:Key="ViewModel"/>

<Style x:Key="DraggableListBoxItem" TargetType="telerik:RadListBoxItem">

<Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" />

</Style

</Window.Resources>

Here's where I display my listboxes

<Grid x:Name="_grid" HorizontalAlignment="Left" Height="436" Margin="10,10,0,0" VerticalAlignment="Top" Width="1297" DataContext="{Binding Source={StaticResource ViewModel}}">

<telerik:RadListBox HorizontalAlignment="Left" Margin="10,48,0,0" VerticalAlignment="Top" Width="106" Height="306" ItemContainerStyle="{StaticResource DraggableListBoxItem}"

ItemsSource="{Binding Segments.AllSegments}" DisplayMemberPath="Code">

<telerik:RadListBox.DragDropBehavior>

<telerik:ListBoxDragDropBehavior />

</telerik:RadListBox.DragDropBehavior>

<telerik:RadListBox.DragVisualProvider>

<telerik:ScreenshotDragVisualProvider />

</telerik:RadListBox.DragVisualProvider>

</telerik:RadListBox>

<telerik:RadListBox HorizontalAlignment="Left" Margin="133,48,0,0" VerticalAlignment="Top" Width="205" Height="306"

ItemsSource="{Binding Segments.SelectedSegments}" DisplayMemberPath="Code" AllowDrop="True">

</telerik:RadListBox>

</grid>

</Window>

For your information: My main ViewModel exposes another viewmodel called Segments which has 2 ObservableCollection<> properties, called AllSegments and SelectedSegments. Both contain the same data type (a viewmodel called Segment).

I was under the impression that I can implement this d&d fully declaratively, since there's no need for data conversion. (Both viewmodels accept the same data type). But the SelectedSegments ObservableCollection is never updated when I drop an item on the target listbox. What am I missing here?

Thanks for responding.

Regards,
~Rob

RadialScale causing COMException inside a TransitionControl when IsInteractive="True"

I'm using a TransitionControl that transitions to a view which uses a RadialGauge with a RadialScale that has IsInteractive set to True. Whenever I load that view, a COMException is thrown with HRESULT 0x88980406. Seems to be related to bitmap rendering in some capacity. The exception is one that appears to be a known bug in .Net, but previous versions of RadControls haven't had this issue.
