GanttView.DurationMapping Property

Provides a path to a data field that stores the task’s duration. This is a dependency property.

Namespace: DevExpress.Xpf.Gantt

Assembly: DevExpress.Xpf.Gantt.v24.2.dll

NuGet Package: DevExpress.Wpf.Gantt

Declaration

C#

public Mapping DurationMapping { get; set; }

VB.NET

Public Property DurationMapping As Mapping

Property Value

Type	Description
Mapping	A Mapping object indicating the data field and the converter.

Remarks

Use the DurationMapping property to bind the Gantt item’s GanttNode.Duration property to a data field. The data field is obtained from the data source specified by the GanttControl’s ItemsSource property.

Tip

Use the Mapping.Converter property to register a value converter for a custom storing format.

You can specify mapping as a Mapping markup extension object, or as a string. The code sample below illustrates how to map Gantt items’ properties to data source fields.

Xaml

<dxgn:GanttControl ItemsSource="{Binding Tasks}">
    ...
    <dxgn:GanttControl.View>
        <dxgn:GanttView
            KeyFieldName="Id"
            ParentFieldName="ParentId"

            NameMapping="{dxgn:Mapping Name}"
            StartDateMapping="StartDate"
            DurationMapping="{dxgn:Mapping Duration}"
            ProgressMapping="Progress"
            BaselineStartDateMapping="BaselineStartDate"
            BaselineFinishDateMapping="BaselineFinishDate"

            PredecessorLinksPath="Links">
            <dxgn:GanttView.PredecessorLinkMappings>
                <dxgn:GanttPredecessorLinkMappings Task="Id" PredecessorTask="PredecessorId"/>
            </dxgn:GanttView.PredecessorLinkMappings>
        </dxgn:GanttView>
    </dxgn:GanttControl.View>
</dxgn:GanttControl>

Note

The task’s duration means the working time span.

Example

You have the following working time rules:

• working time per day is 8 hours,
• task’s duration is set to 1 day (24 hours).

In this case, the tasks duration is 24 working time hours (3 working days).
