Hi,
I am using Silverlight Telerik GanttChart. Can you please suggest me to add the dependency to the tasks and also need to Include the tick interval Daily, Monthly,weekly based on checkboxor button click event or dropdown change event.
Please refer my xaml and c# code as below:
XAML code:

<UserControl.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/Telerik.Windows.Themes.Metro;component/Themes/System.Windows.xaml" />

<ResourceDictionary Source="/Telerik.Windows.Themes.Metro;component/Themes/Telerik.Windows.Controls.xaml" />

<ResourceDictionary Source="/Telerik.Windows.Themes.Metro;component/Themes/Telerik.Windows.Controls.GanttView.xaml" />

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</UserControl.Resources>

<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.Columns>

<telerik:TreeColumnDefinition>

<telerik:TreeColumnDefinition.CellTemplate>

<DataTemplate>

</DataTemplate>

</telerik:TreeColumnDefinition.CellTemplate>

</telerik:TreeColumnDefinition>

<telerik:ColumnDefinition MemberBinding="{Binding Title}" Header="Activities" ColumnWidth="160">

</telerik:ColumnDefinition>

<telerik:ColumnDefinition MemberBinding="{Binding Start}" Header="Start" ColumnWidth="120">

</telerik:ColumnDefinition>

<telerik:ColumnDefinition MemberBinding="{Binding End}" Header="End" ColumnWidth="120">

</telerik:ColumnDefinition>

<telerik:ColumnDefinition MemberBinding="{Binding Duration}" Header="Duration" ColumnWidth="100">

</telerik:ColumnDefinition>

<telerik:ColumnDefinition MemberBinding="{Binding Progress}" Header="Progress" ColumnWidth="100">

Hi kanna,

If you like to add a Dependency to your task, you need to create a new Dependency which property FromTask points to the related task. The following line of code demonstrates this.

ourSecundTask.Dependencies.Add(new Dependency { FromTask = yourFirstTask });

In your case you need to create a custom Task, because you have a additional property like ExecutableFlag. In order to create an custom task you need to inherit from GanttTask or implement IGanntTask interface. We added a sample project to illustrate how it works.
