Resource Load View

The Gantt library now includes some utility classes that helps you compute the resources' load over a specific time span, take that information and build a resource load view using our FlexyGantt.

ResourceLoadTracker is the utility class that is capably of providing you load information for a resource given a GanttControl's Model instance.

Here is the Resource Load View (at the bottom) built using the above ResourceLoadTracker and the FlexyGantt.

Resource Load View

This is illustrated in the sample <install path>\Samples\ProjectGantt\Scheduling\ResourceLoadView.

Step 1: ResourceLoadTracker

When you are ready to get the load information from the ResourceLoadTracker, you can do as follows:

private void Refresh_Click(object sender, RoutedEventArgs e)

{

this._loadTracker = new ResourceLoadTracker(this.ganttControl.Model, this.Dispatcher);

this.flexyGantt.ItemsSource = this._loadTracker.ResourceLoadLists;

}

Initialize the tracker with the following:

a) IGanttModel instance - the tracker then builds the load information for all the Resources that are currently in the Model.

b) Optional Dispatcher instance - Providing this, will make the tracker keep the load-information up to date as the resources get reassigned to tasks, etc.

Then simply assign the ResourceLoadLists as the FlexyGantt's ItemsSoruce as above.

Note that the above list contains a ResourceLoadList instance for each Resource in the GanttControl's Model.

A ResourceLoadList then contains the load information as an array of LoadInfo instances (LoadInfos property) like this :

{

TimePeriod: 1/15/2014 8AM - 2/15/2014 4PM;

LoadPerc: 110; // A double value

etc.

Step 2: Customizing FlexyGantt

Apply appropriate templates to the FlexyGantt to make it show the load information as bars within the time ranges.

<fxgantt:FlexyGantt RowHeight="60" TaskListBinding="{Binding LoadInfos}" TaskStartTimeBinding="{Binding TimePeriod.Start, Mode=OneWay}"

TaskEndTimeBinding="{Binding TimePeriod.End, Mode=OneWay}" TreeHeaderContent="Resources"

CustomSourceListViewTemplate="{StaticResource flexyGanttTableTemplate}">

<fxgantt:FlexyGantt.TaskItemTemplate>

<Border ToolTipService.ToolTip="{Binding}" VerticalAlignment="Bottom" Background="{Binding LoadPerc, Converter={StaticResource loadToBrushConverter}}"

Height="{Binding LoadPerc, Converter={StaticResource loadToHeightConverter}}" >

</Border>

</DataTemplate>

</fxgantt:FlexyGantt.TaskItemTemplate>

</fxgantt:FlexyGantt>

Note that the height and color of the bars is bound to the LoadPerc value in the TaskItemTemplate above.

The required converters are implemented in the above mentioned sampled.
