Mappings

When you bind the GanttControl to a data source, you need to map the GanttNode properties to data source fields.

In real-world applications, the names of the database fields are usually fixed, and you cannot change them. Mappings are used to adjust the GanttControl data model to the existing data model.

Mapping	Data Type	Description
NameMapping	String	Maps to the GanttNode.Name property. Provides a path to a data field that stores the task’s name.
ProgressMapping	Double	Maps to the GanttNode.Progress property. Provides a path to a data field that stores the task’s progress.
StartDateMapping	DateTime	Maps to the GanttNode.StartDate property. Provides a path to a data field that stores the task’s start date.
FinishDateMapping	DateTime	Maps to the GanttNode.FinishDate property. Provides a path to a data field that stores the task’s finish data.
DurationMapping	TimeSpan	Maps to the GanttNode.Duration property. Provides a path to a data field that stores the task’s duration.
BaselineStartDateMapping	DateTime	Maps to the GanttNode.BaselineStartDate property. Provides a path to a data field that stores the task baseline’s start date.
BaselineFinishDateMapping	DateTime	Maps to the GanttNode.BaselineFinishDate property. Provides a path to a data field that stores the task baseline’s finish date.
BaselineDurationMapping	TimeSpan	Maps to the GanttNode.BaselineDuration property. Provides a path to a data field that stores the task baseline’s duration.

The code sample below demonstrates how to specify mappings.

Xaml

<dxgn:GanttControl ItemsSource="{Binding Tasks}">
    <dxgn:GanttControl.View>
        <dxgn:GanttView
            AutoExpandAllNodes="True"
            TreeDerivationMode="Selfreference"
            KeyFieldName="Id"
            ParentFieldName="ParentId"
            StartDateMapping="Start"
            FinishDateMapping="Finish"
            NameMapping="Name" />
    </dxgn:GanttControl.View>
</dxgn:GanttControl>

Tip

You have no need to specify mappings when the GanttControl is bound to a collection of GanttTask objects.
