A task is a unit of work. On the Gantt chart, it displays the following information:

• Task title.

• Duration (start and end dates).

• Task progress.

• Associated dependencies that specify relationships between tasks.

• Associated resources.

A large task can be divided into subtasks that allow you to track the progress.

A milestone is a task with the same start and endpoint. Milestones can be used as checkpoints for important points in a project.

The Gantt gets data for tasks from a data source (TasksDataSourceID). Use the Task object to specify which fields in the data source correspond to task properties.

ASPX

<dx:ASPxGantt ID="Gantt" runat="server" TasksDataSourceID="TasksDataSource" ... >
    <Mappings>
        <Task Key="ID" ParentKey="ParentID" Title="Subject" Start="StartDate" 
        End="EndDate" Progress="PercentComplete" Color="Color" />
        ...
    </Mappings>
    ...
</dx:ASPxGantt>

<asp:SqlDataSource ID="TasksDataSource" runat="server" 
ConnectionString='<%$ ConnectionStrings:DevelopmentGanttConnectionString %>' 
SelectCommand="SELECT * FROM [Tasks]" />

The table below lists the main members that affect task appearance and functionality.
