GridControl.GetDetail(Int32, DataControlDetailDescriptor) Method

Returns the detail data control identified by the master row and its Detail Descriptor.

Namespace: DevExpress.Xpf.Grid

Assembly: DevExpress.Xpf.Grid.v23.2.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

C#

public DataControlBase GetDetail(
    int rowHandle,
    DataControlDetailDescriptor descriptor = null
)

VB.NET

Public Function GetDetail(
    rowHandle As Integer,
    descriptor As DataControlDetailDescriptor = Nothing
) As DataControlBase

Parameters

Name	Type	Description
rowHandle	Int32	An integer value identifying the master row by its handle.

Optional Parameters

Name	Type	Default	Description
descriptor	DataControlDetailDescriptor	null	Optional. A DataControlDetailDescriptor object that identifies the detail in case multiple details are available at this level. If not specified while multiple details are available, the first available detail data control is returned.

Returns

Type	Description
DataControlBase	A DataControlBase descendant which displays detail data. Returns null (Nothing in Visual Basic) if no DataControlDetailDescriptor objects are used as details on this level or if corresponding details are collapsed.

Remarks

When you set up a master-detail hierarchy within a GridControl, you create Detail Descriptor objects which contain settings used to create actual detail controls. While there’s a single Detail Descriptor (template), there can be multiple detail controls - one per each expanded detail.

The GetDetail method returns the actual data control that displays detail data for the specified master row. This can be any DataControlBase descendant, but it will typically be a GridControl. If there are multiple details displaying data via DataControlBase descendants, you can identify the one you want to get by its corresponding template - DataControlDetailDescriptor object.

Note

The GetDetail method works with DataControlDetailDescriptor objects only.
