New Post: Remove "Powered by Xceed" header

Hi,

Very good your program...but I have a problem, no work !!!

<Grid>             
        <avalonDock:DockingManager x:Name="DockManager">
            <avalonDock:LayoutRoot>
                <avalonDock:LayoutPanel Orientation="Horizontal">
                    <avalonDock:LayoutDocumentPane>
                        <avalonDock:LayoutAnchorable x:Name="Pannel1" DocumentViewerBase.IsMasterPage="True" CanClose="False">
                            <Grid Name="MonGrid">                                
                                <xcdg:DataGridControl x:Name="_dataGrid" AutoCreateColumns="True" ItemsSource="{Binding MaCollection}"></xcdg:DataGridControl>   
                            </Grid>    
                        </avalonDock:LayoutAnchorable>                        
                    </avalonDock:LayoutDocumentPane>                    
                </avalonDock:LayoutPanel>                
            </avalonDock:LayoutRoot>            
        </avalonDock:DockingManager>
    </Grid>

The watermark is always visible, I'm a bug on the "Dim child = VisualTreeHelper.GetChild(parent, i)", this return the value 0 ???

Thank you for your help.
