[Tomas]

Halo, we have a serious problem with RadDocking when we use custom header template.
If we use in DocumentHost custom template for header of RadPane and there is Button in the RadPane header, after click on this button docking operation is imediatelly started and the RadPane became floating :-(
There is sample code:

<Window x:Class="DarDataFormTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:local="clr-namespace:DarDataFormTest"
        Title="MainWindow" Height="350" Width="525">

    <Window.Resources>

        <RoutedCommand x:Key="CommitCommand"/>

        <RoutedCommand x:Key="CancelCommand"/>

        <local:Converter x:Key="conv"/>
    </Window.Resources>

    <Grid>
        <telerik:RadDocking x:Name="radDocking1"  BorderThickness="0"  Padding="0">

            <!--DocumentHost-->
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup>

                        <telerik:RadDocumentPane Title="Description">
                            <telerik:RadDocumentPane.HeaderTemplate>
                                <DataTemplate>
                                    <StackPanel  Orientation="Horizontal">
                                        <TextBlock Text="aaaa" />
                                        <Button Margin="2">Butt</Button>
                                    </StackPanel>
                                </DataTemplate>
                            </telerik:RadDocumentPane.HeaderTemplate>
                            <telerik:RadDocumentPane.Content>
                                <TextBlock TextWrapping="Wrap"
                                           Text="test text" />
                            </telerik:RadDocumentPane.Content>
                        </telerik:RadDocumentPane>

                    </telerik:RadPaneGroup>
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>

        </telerik:RadDocking>

    </Grid>
</Window>
