Restrict item selection
18 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;

/// <summary>

public ViewModel()
{
this.taskCollections = GetData();
