ContextMenus

Sample (Samples\ProjectGantt\UserInteraction\CustomizingMenus) illustrates adding ContextMenus to GanttControl area.

Gantt Table Context Menus

You can easily add custom ContextMenus to the DataGridRow representing each row in the GanttTable. You can do so as follows in XAML, under the resources section:

</Setter>

</Style>

Resultant context menu:

ContextMenu for each DataGridRow

In the Click event handlers, you can access the bound Activity and data bound task as follows:

private void deleteTask_Click(object sender, RoutedEventArgs e)

{

// If the selected activity is a parent then all it's children will have to be removed too.

// So, always use this pattern.

IActivity selectedActivity = this.ganttControl.SelectedActivity;

// This will remove the activities from the Gantt UI.

// You should then remove the corresponding bound items in the data source.

List<IActivity> allRemoved = this.ganttControl.RemoveActivity(selectedActivity.ID);

foreach (IActivity removedActivity in allRemoved)

{

this.dataSource.Remove(((DataBoundActivity)removedActivity).DataSource as TaskInfo);

}

Gantt Chart Task Bar Context Menu

Associate a ContextMenu with the GanttTaskItemBar type to show context menus on right clicking on each bar as follows (in XAML, under resources):

</Setter>

</Style>

Custom ContextMenu associated with task bars

In the Click event handler, you can access the activity and the bound task item as follows:

private void customTask_Click(object sender, RoutedEventArgs e)

{

MenuItem mi = e.OriginalSource as MenuItem;

ContextMenu cm = mi.Parent as ContextMenu;

IActivityView activityView = cm.DataContext as IActivityView;

MessageBox.Show(string.Format("TaskInfo context in chart: Name: {0}; StartTime: {1}", activityView.Activity.ActivityName, activityView.Activity.StartTime.ToShortDateString()));

}
