How to delete a dependency

[Steven]

Since the relation could not be selected on the GanttView, and there are not way to delete such relation.

I tried, to create column to show all dependency of a task as beloging:
 

<telerik:ColumnDefinition MemberBinding="{Binding DependencyDisplay}" Header="Dependency" ColumnWidth="100" >
	<telerik:ColumnDefinition.CellEditTemplate>
		<DataTemplate>
                           <telerik:RadComboBox VerticalAlignment="Center" x:Name="DependencyCombo"
				ItemsSource="{Binding Dependencies}" ItemTemplate="{StaticResource ComboBoxCustomTemplate2}"
				SelectionBoxTemplate="{StaticResource ComboBoxSimpleTemplate}"  />
		</DataTemplate>
	</telerik:ColumnDefinition.CellEditTemplate>
</telerik:ColumnDefinition>

My Intention was, when a user deselected a checkbox(inside the combobox) , will send a command to the ViewModel.

My problem is:
1- At the ViewModel, Because The GanttView Lost it focus, the SelectedItem is null.
2- Since SelectedItem is null, I will need to pass 2 parameter in CommandParameter, how could I do that?


are there any good way to manipulate relation deletion?

Hi,

Currently there is no built in way to remove dependencies. I have prepared a sample project that demonstrates one way to do this using a RadAutoCompleteBox in a ColumnDefinition. Have in mind this example shows an approach how to achieve this and it is not fully complete.  We will do our best to provide a complete example in our online resources for one of the future versions of RadControls.
