Windows Explorer Demo

I have followed the Windows Explorer Treeview demo you have and everything works fine except that my Directory objects never have the expansion sign next to it, even though they all have sub folders and files. I have tried troubleshooting many different things. For example, in the Style Selector I made Directory use the Drive style because its expander works. But it makes no difference. The Style is definitely being used as I have tested it. Does it have to do with it being on a Windows 7 box? I ran the program as an Administrator as I was desperate and it had no effect.

Drag and Drop in MVVM was broken when I upgraded contols

I have an MVVM project with Several RadGridViews inside of a RadTabControl and a RadTabControl containing Listboxes which are defined in an datatemplate.
I had Drag and Drop working fine when using version 2011.2.712.40
However, when I upgraded to the current release the drag and drop functionality does not work.

I found the following thread (see below) and downloaded the last example contained within, sure enough it has the same problem...
if you run the example with the version contained in the lib folder Drag and Drop works fine, then if you upgrade the controls to the current version, Drag and Drop no longer functions.

http://www.telerik.com/community/forums/wpf/draganddrop/drag-drop-related-problem-in-mvvm.aspx

What has changed that would impact Drag and Drop, and how can I correct it?

How to collapse RadGridView RowDetailsTemplate

I currently have a RadGridView with a RowDetailsTemplate that expands when a row is selected by using RowDetailsVisibilityMode="VisibleWhenSelected". When I click on another row, the previously selected row collapses and the new row expands like I want. However, how do I make the selected row collapse when I click on the selected row a second time instead of clicking on a different row? I'm basically trying to get back to where all rows are collapsed. I am not using the '+' button control so it will have to respond to a click anywhere on the selected row. Thanks.

Drag & Drop Effects

Hello,

I'm evaluating the TreeView of "RadControls for WPF Q3 2011 SP1" on Windows 7.
I'm using the version 2011.3.1220.40 of Telerik.Windows.Controls.Navigation.

I want to use the drag and drop capabilities of the TreeView.
But it seems that the property Effects of the DragDropEventArgs object is always null.

public TelerikTreeview()

{

InitializeComponent();

RadDragAndDropManager.AddDropQueryHandler(m_cellTreeView, new EventHandler<DragDropQueryEventArgs>(OnDropQuery));

}

private void OnDropQuery(object sender, DragDropQueryEventArgs e)

{

System.Diagnostics.Debug.WriteLine(e.Options.Effects);

}

How do you perform a copy or move operation with your drag & drop ?

Best regards.

Attaching Appointments to ResourceType

I have an ObservableCollection that currently only has one ResourceType in it: Provider. I have 3 Providers in that ResourceType. I have a collection of Appointments that I have attached to the AppointmentSource. When I did not have any ResourceType attached the appointments would appear in the scheduler just fine. I have added the ResourceType and they are displaying correctly, but the appointments are not showing. My collection of appointments is correctly populating still. I have tried attaching the specific Provider I need to the Appointment's Resource, but I still cannot get them to show. I am lost and would love any help that could be given.

Error in InvertedBooleanConverter

I noticed in my application that InvertedBooleanConverter (in the ScheduleView dll) was not working correctly for the convert back operation. I looked at it in JustDecompile and it is incorrect.

The InvertedBooleanConverter in Telerik.Windows.Controls.dll is correct.

Why are there multiple versions?

Changing Zoom from Code

I am using the ChartView control, and would like to be able to change the Zoom from code.
I have tried two things.

1. Set Zoom property directly from code.
i.e. Chart.Zoom = new Size(1,1);

2. Bind to a Zoom property on my view model, and set that property.

i.e. XAML gets

<telerik:RadCartesianChart Name="Chart" Zoom="{Binding Path=Zoom, Mode=TwoWay}">

And code gets
ViewModel.Zoom = new Size(1,1);

Either way, the view is not refreshed correctly. However, on a re-size operation, it becomes OK again.

Is this a known problem, or is there something else I need to do?

Thanks
