GanttView supports three kinds of resources namely work resource, material resource, and cost resource described further as follows:

The following image shows a resource assigned to a task in GanttView.

Creating, adding and assigning resources to tasks

GanttView provides the Resource class for handling resources. To create and manage resources, you need to create an instance of the Resource class and set its name and cost using the Name and Cost properties, respectively. The ResourceType property can be set to specify the type of resource. The ResourceType property accepts the following values from the ResourceType enumeration:

• Work - Specifies a work resource.
• Material - Specifies a material resource.
• Cost - Specifies a cost resource.

The TaskResources class also provides the Add method to add the resources to a locally-defined resource dictionary. However, simply creating a resource is of no use until it is assigned to a task for which the control provides the ResourceRef class. You need to create an object of the ResourceRef class, set its Resource property, and add the same to the task using the Add method.

The following code example illustrates creating, adding, and assigning resource to a task. This example uses the sample created in the Quick Start.

'Creating a resource
Dim r As New Resource()
r.ResourceType = ResourceType.Work
r.Name = "Gary"
r.Cost = 300D

'Adding the resource to gantt view
gv.TaskResources.Add(r, "Gary")

'Assigning the resource to task 't1'
Dim t1 As Task = gv.Tasks.Search("Requirement Gathering")
If t1 IsNot Nothing AndAlso t1.ResourceRefs.Count = 0 Then
    Dim rRef As New ResourceRef()
    rRef.Resource = r
    rRef.Amount = 0.5
    t1.ResourceRefs.Add(rRef)
End If

//Creating a resource
Resource r = new Resource();
r.ResourceType = ResourceType.Work;
r.Name = "Gary";
r.Cost = 300m;

//Adding the resource to gantt view
gv.TaskResources.Add(r, "Gary");

//Assigning the resource to task 't1'
Task t1 = gv.Tasks.Search("Requirement Gathering");
if (t1 != null && t1.ResourceRefs.Count == 0)
{
    ResourceRef rRef = new ResourceRef();
    rRef.Resource = r;
    rRef.Amount = 0.5;
    t1.ResourceRefs.Add(rRef);
}
