Sub-GridView (details) databinding MVVM

Hi, This may be a WPF Databinding question but I think this should be simple.

I have a RadGridView that displays a collection of objects and allows a user to drill down into a subcollection of the databound object. I use the following XAML to define the GridView:

    
             <telerik:RadGridView ItemsSource="{Binding L2SClasses}" ColumnsWidthMode="Fill" telPres:StyleManager.Theme="Vista" CanUserInsertRows="False" CanUserDeleteRows="False" IsReadOnly="True" 
        
                                                     SelectedItem="{Binding SelectedClass}" AutoGenerateColumns="False"  ShowGroupPanel="False" > 
        
                                    <telerik:RadGridView.Columns> 
        
                                        <telerik:GridViewToggleRowDetailsColumn /> 
        
                                        <telerik:GridViewDataColumn Header="Class Name">  
        
                                            <telerik:GridViewDataColumn.CellTemplate> 
        
                                                <DataTemplate> 
        
                                                    <TextBlock Text="{Binding ClassName}" /> 
        
                                                </DataTemplate> 
        
                                            </telerik:GridViewDataColumn.CellTemplate> 
        
                                        </telerik:GridViewDataColumn> 
        
                                    </telerik:RadGridView.Columns> 
        
                                    <telerik:RadGridView.RowDetailsTemplate> 
        
                                        <DataTemplate> 
        
                                            <telerik:RadGridView ItemsSource="{Binding Properties}" CanUserInsertRows="False" CanUserDeleteRows="False" IsReadOnly="True" ColumnsWidthMode="Fill" 
        
                                         telPres:StyleManager.Theme="Vista" MaxWidth="600" ShowGroupPanel="False" SelectedItem="{Binding SelectedProperty,Mode=TwoWay}">  
        
                                                <telerik:RadGridView.Columns> 
        
                                                    <telerik:GridViewDataColumn Header="Name">  
        
                                                        <telerik:GridViewDataColumn.CellTemplate> 
        
                                                            <DataTemplate> 
        
                                                                <TextBlock Text="{Binding Name}" /> 
        
                                                            </DataTemplate> 
        
                                                        </telerik:GridViewDataColumn.CellTemplate> 
        
                                                    </telerik:GridViewDataColumn> 
        
                                                    <telerik:GridViewDataColumn Header="Type">  
        
                                                        <telerik:GridViewDataColumn.CellTemplate> 
        
                                                            <DataTemplate> 
        
                                                                <TextBlock Text="{Binding Type}" /> 
        
                                                            </DataTemplate> 
        
                                                        </telerik:GridViewDataColumn.CellTemplate> 
        
                                                    </telerik:GridViewDataColumn> 
        
                                                    <telerik:GridViewColumn> 
        
                                                        <telerik:GridViewColumn.CellTemplate> 
        
                                                            <DataTemplate> 
        
                                                                <Button Content="Add to Model >>" Name="btnAddToModel" Click="btnAddToModel_Click" /> 
        
                                                            </DataTemplate> 
        
                                                        </telerik:GridViewColumn.CellTemplate> 
        
                                                    </telerik:GridViewColumn> 
        
                                                </telerik:RadGridView.Columns> 
        
                                            </telerik:RadGridView> 
        
                                        </DataTemplate> 
        
                                    </telerik:RadGridView.RowDetailsTemplate> 
        
                                </telerik:RadGridView>

The SelectedItem of the master GridView works great. When a row is selected the SelectedItem is set in my ViewModel. The problem is that the same functionality is not happening in the child GridView. I think I need to define the DataContext on the sub GridView somehow but I am unsure of how to do this. I would like the sub-GridView (child) to set the SelectedProperty property of my ViewModel but it does not work.

Any assistance would be greatly appreciated!

Thanks,
David Sandor

Disabling ticks on a slider

Is there a way (example) to disable (in code) ticks on a RadSlider? Practically, imagine two sliders, one shows years, the other Months. When you select the current year and it is July all months AFTER that would be disabled and the slider would not go to them (would stop at July).

Thanks!

Binding SelectedItems with Behavior

I'm trying to bind RadGridView SelectedItems property to a property on my ViewModel using the custom Behavior approach mentioned in the blog post, but it's not working.

I remember some folks having trouble with it when setting the dataContext at runtime rather than as a static resource. I'm using Prism's Dependency Injection to inject the viewModel into a property on the View. I can see that my ObservableCollection on my viewModel is being populated, but it's not showing up as selected items on my grid.

I need help getting this to work properly.

Drag to specific slot from external source

I'm trying to implement dragging from a ListBox onto a ScheduleView, using DragAndDropManager. I'm as far as the DropInfo handler on the view where the ScheduleView resides running, and am successfully getting the information that I want from the ListBox. What I can't figure out is how to find out which slot I am trying to drop into. DragDropEventArgs.Options.CurrentDragPoint would seem a promising way to this information, and the demos show how to so this for the old Scheduler control, but ScheduleView appears to operate differently. The only other piece of information that I can find suggests that DefaultDragDropBehavior.ValidateExternalDrag "could be used to add the appointments from external source".

Is there a simple example available demonstrating how to drag from an external non-ScheduleView source onto a specific slot within a ScheduldeView in order to create a new appointment based on the dragged-in object? If not, would it at least be possible to provide some pointers as to how I can achieve this?

Thanks
Ryszard
