The Gantt control can operate only in bound mode. It supports standard data source types including SqlDataSource, ObjectDataSource, XmlDataSource, AccessDataSource, and SiteMapDataSource.
Data Source
The Gantt control requires a separate data source for each of the following objects:

Example:
<dx:ASPxGantt ID="Gantt" runat="server" Width="100%" ClientInstanceName="clientGantt"
KeyFieldName="ID" ParentFieldName="ParentID"
TasksDataSourceID="TasksDataSource"
DependenciesDataSourceID="DependenciesDataSource"
ResourcesDataSourceID="ResourcesDataSource"
ResourceAssignmentsDataSourceID="ResourceAssignmentsDataSource">
...
</dx:ASPxGantt>
<asp:SqlDataSource ID="TasksDataSource" runat="server"
ConnectionString='<%$ ConnectionStrings:DevelopmentGanttConnectionString %>'
SelectCommand="SELECT * FROM [Tasks]" />
<asp:SqlDataSource ID="DependenciesDataSource" runat="server"
ConnectionString='<%$ ConnectionStrings:DevelopmentGanttConnectionString %>'
SelectCommand="SELECT * FROM [TaskDependecies]" />
<asp:SqlDataSource ID="ResourcesDataSource" runat="server"
ConnectionString='<%$ ConnectionStrings:DevelopmentGanttConnectionString %>'
SelectCommand="SELECT * FROM [Teams]" />
<asp:SqlDataSource ID="ResourceAssignmentsDataSource" runat="server"
ConnectionString='<%$ ConnectionStrings:DevelopmentGanttConnectionString %>'
SelectCommand="SELECT * FROM [TaskTeamRelations]" />
Mappings
Mappings specify which field in a data source corresponds to an object's property (task, dependency, resource).
The Gantt control requires mappings for the following objects:
Task (Task)
Mandatory fields for a task object:
Field description

| Start
|
A task's end date.
| End
|
Dependency (Dependency)
Mandatory fields for a dependency object:
Resource (Resource)
Mandatory fields for a resource object:
Field description
| Mapping
|
|---|
Task's resource ID.
| Key

Resource Assignment (ResourceAssignment)
Mandatory fields for a resource assignment object:
Field description
| Mapping
|
|---|
A task's resource assignment ID.
| Key
|
A task's resource ID.
| ResourceKey
|
A task's ID.
| TaskKey
