• GetDependencyDataRow(Int32, Int32) — Returns a DataRow in the bound DataTable that contains data for the specified dependency.

To specify the node in the method’s parameter, use the node’s Id property value.

The SetDependency(GanttControlNode, GanttControlNode, DependencyType, TimeSpan) method allows you to specify a dependency in code.

You can also use the following methods to get an object that contains data for a specific node:
