Hi,
I am using GanttView for Silverlight and i am using collection to Bind the data(not in MVMM method in online example).
Please let me know how to include the Zoom option to the collection and also i want a suggestion to add the dependency for the below code (binding data to Collection).

Please find my code as below.
Regards,
Kannan

XAML code:
<Grid x:Name="LayoutRoot" Background="White">
       <!--<telerik:RadGanttView Name="xGanttView" HorizontalAlignment="Left" Margin="18,1,0,0" VerticalAlignment="Top" Width="Auto" />-->
       <telerik:RadGanttView x:Name="ganttview"  BorderBrush="#FFD6D4D4" Width="1000"
               BorderThickness="1 0 1 1"
                Grid.Row="1" Margin="0 6 0 0">
           <telerik:RadGanttView.TimeRulerLines>
               <telerik:GroupTickLine>
                   <telerik:TickInterval Interval="OneMonth" FormatString="{}{0:MMMM, yyyy}" />
               </telerik:GroupTickLine>
               <telerik:MajorTickLine>
                   <telerik:TickInterval Interval="OneDay" FormatString="Day {0:dd}" />
               </telerik:MajorTickLine>
 
           </telerik:RadGanttView.TimeRulerLines>
 
 
           <telerik:RadGanttView.Columns>
               <telerik:TreeColumnDefinition MemberBinding="{Binding Title}" Header="" ColumnWidth="5">
                
               </telerik:TreeColumnDefinition>
