Restrict item selection

26 Jul 202418 minutes to read

To restrict item selection, set the SelectionMode property of the GanttControl to None.

The following codes illustrate this

<gantt:GanttControl x:Name="gantt"
                    ItemsSource="{Binding TaskDetails}"
                    SelectionMode="None">
    <gantt:GanttControl.DataContext>
        <local:ViewModel/>
    </gantt:GanttControl.DataContext>
</gantt:GanttControl>
this.gantt.ItemsSource = new ViewModel().TaskCollection;
this.gantt.SelectionMode = GanttSelectionMode.None;

public class ViewModel
 {
    /// <summary>
    /// Holds the task collections.
    /// </summary>
    private ObservableCollection<TaskDetails> taskCollections;

    /// <summary>

    /// </summary>
    public ViewModel()
    {
        this.taskCollections = GetData();
    }

        }
        set
        {
            this.taskCollections = value;
        }
    }
