GanttControl.SetDependency(GanttControlNode, GanttControlNode, DependencyType, TimeSpan) Method

Allows you to specify a dependency between two tasks.

Namespace: DevExpress.XtraGantt

Assembly: DevExpress.XtraGantt.v25.1.dll

NuGet Package: DevExpress.Win.Gantt

Declaration

C#

public void SetDependency(
    GanttControlNode predecessorNode,
    GanttControlNode successorNode,
    DependencyType type,
    TimeSpan lag
)

VB.NET

Public Sub SetDependency(
    predecessorNode As GanttControlNode,
    successorNode As GanttControlNode,
    type As DependencyType,
    lag As TimeSpan
)

Parameters

Name	Type	Description
predecessorNode	GanttControlNode	An object that specifies the predecessor task (node).
successorNode	GanttControlNode	An object that specifies the successor task (node).
type	DependencyType	A value that specifies a dependency type.
lag	TimeSpan	A value that specifies a time lag between the predecessor and successor tasks.

Remarks

Use the following methods to get an object that contains data for a specific dependency:

• GetDependencyRow(Int32, Int32) — Returns an Object in the bound data source that contains data for the specified dependency.

• 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:

• GetRow(Int32) — Returns an Object in the bound data source that contains data for the specified node.

  To get the focused node’s data row, use the GetFocusedRow() method.

• GetDataRow(Int32) — Returns a DataRow in the bound DataTable that contains data for the specified node.

  To get the focused node’s DataRow, use the GetFocusedDataRow() method.

  Note

  If the bound data source is a custom collection, these methods return null (Nothing in VB).
