GridView.MasterRowGetLevelDefaultView Event

Enables you to specify a pattern view to represent a particular detail.

Namespace:DevExpress.XtraGrid.Views.Grid
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type MasterRowGetLevelDefaultViewEventArgs containing data related to this event.

The following MasterRowGetLevelDefaultViewEventArgs properties provide information specific to this event.
Property Description
DefaultView Gets or sets a pattern view to represent the detail View.
RelationIndex Gets the relation index that identifies the affected detail.
RowHandle Gets the handle of the currently processed master row in the current View.

Expanded Remarks

Handle the MasterRowGetLevelDefaultView event to specify a pattern view that will represent a particular detail. The current detail can be identified using the event's CustomMasterRowEventArgs.RowHandle and CustomMasterRowEventArgs.RelationIndex parameters. To specify the pattern view, use the MasterRowGetLevelDefaultViewEventArgs.DefaultView parameter.

The event should be handled in the following cases:

  • when you need to specify the pattern View for individual detail clones. For instance, the master View can have a single child relation. You can handle the MasterRowGetLevelDefaultView event to represent detail clones corresponding to different master rows using different Views;
  • when you provide detail data dynamically. Please refer Master-Detail: Using Events document for additional information regarding this.

The MasterRowGetLevelDefaultView should be handled if you need to provide Views that don't belong to the GridControl.LevelTree tree. Otherwise, handle the MasterRowGetRelationName event to specify the View by the corresponding level name. Note that the MasterRowGetLevelDefaultView event overrides the MasterRowGetRelationName event.
