How to keep busy indicator spinning during binding?

I fetch my data and populate the underlying ObservableCollection with the fetched data on a background thread using the TPL, during that time the busy indicator is spinning fine. However, once my data is fetched the ICollectionView my RadDataGird is bound to starts refreshing and the busy indicator freezes until the binding is finished which takes longer than fetching the data and makes the UI look unresponsive...

Now, it makes sense because both the data binding and the busy indicator are running on the UI thread but if that is the case what is the solution to keep the busy indicator spinning during the data binding?

Is there any way to have the busy indicator run on a separate thread?

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
