Hi,

I have created sample solution which uses RadDocking with MVVM approach: https://skydrive.live.com/redir?resid=51A46BBA4E9EF07E!1215

<telerik:RadDocking x:Name="dockManager"

local:DockingExtensions.PaneSource="{Binding LayoutPanes}"

local:DockingExtensions.ActivePane="{Binding ActivePane, Mode=TwoWay}">

<telerik:RadDocking.Resources>

<Style TargetType="telerik:RadPane">

<Setter Property="Header" Value="{Binding Name}" />

<Setter Property="Content" Value="{Binding View}" />

<Setter Property="CanDockInDocumentHost" Value="False" />

</Style>

<Style TargetType="telerik:RadDocumentPane">

<Setter Property="Header" Value="{Binding Name}" />

<Setter Property="Content" Value="{Binding View}" />

<Setter Property="CanDockInDocumentHost" Value="True" />

</Style>

<Style TargetType="telerik:ToolWindow">

<Setter Property="Header" Value="{Binding Name}" />

<Setter Property="Content" Value="{Binding View}" />

<Setter Property="ToolTip" Value="This style is not applied when radpane is dragged. Why?" />

</Style>

</telerik:RadDocking.Resources>

<telerik:RadSplitContainer />

</telerik:RadDocking>

there's DockingExtensions.cs file with attached property called 'PaneSource'. This property generates RadPanes from it's value, see addRadPane method it that file.

When the RadPane is being generated, addRadPane method sets datacontext to radpane
RadPane pane = ...

pane.DataContext = paneVM;

Works fine, until I make the pane floatable. Seems like the datacontext is not preserved when after radpane is moved to toolwindow.

My questions are:
1. How to extend DockingExtensions to support floating panes?
2. Why my style for ToolWindow isn't applied (see code above)
3. Can I disable floating functionality but allow user do reorder panes? setting CanFloat to false makes imposibble to drag&drop panes

DatePicker for touchscreen

More in particular for selecting date of birth.

Is there an option available to show only years when opening the control.

After selecting a year we show the months and afterwards the days. After selecting the day, the final date of birth is filled in in the control.

This would avoid a lot of extra touch events for our users.

Could this work by switching the selection from year/mont/day between each selection. Can we avoid the popup from opening.closing every time?

Thank you for your support.

RadPieChart and PivotChartViewModel

I'm trying to bind a RadPieChart to data the user has selected using the RadPivotFieldList. I would like to know how to customise the labels and also how to use the legend with the PieSeries data.

Below is what I have so far, I maybe wildly off the mark with how I'm approaching this. Any feedback would be welcome.

Thanks

<pivot:RadPivotFieldList x:Name="FieldList" DataProvider="{Binding DataProvider}"/>

<telerik:RadPieChart x:Name="pieChart" Grid.Column="1" Palette="Windows8" DataContext="{Binding ChartViewModel}">

<telerik:PieSeries ValueBinding="Value" ItemsSource="{Binding SeriesSource[0].Items}" ShowLabels="True" >

</telerik:PieSeries>

</telerik:RadPieChart>

In the viewmodel

public LocalDataSourceProvider DataProvider

{

get => _dataProvider;

set

{

_dataProvider = value;

OnPropertyChanged(() => DataProvider);

}

public PivotChartViewModel ChartViewModel { get; set; }

I'm setting the DataProvider of the ChartViewModel like this.

ChartViewModel.DataProvider = DataProvider
