Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v23.2.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation


public BaseView GetDetailView(
    int rowHandle,
    int relationIndex


Name Type Description
rowHandle Int32

The master row handle.

relationIndex Int32

The relationship index in the data source.


Type Description

A BaseView descendant that is the detail clone. null (Nothing in Visual Basic) if the specified detail clone does not exist.


The GetDetailView method returns a detail View if the detail View is visible. You need to display the ditail view if it is hidden.

Use the GridView.GetMasterRowExpanded method to obtain a master row’s expanded state. Use the GridView.SetMasterRowExpanded or GridView.SetMasterRowExpandedEx method to expand the master row.

The relationIndex parameter specifies the detail View’s relationship index if the master row has several details.

The order of detail Views may not match the order of detail relationships in the data source. Take this into consideration when specifying the relationIndex parameter, which identifies the index of the relationship in the underlying data source.

To get the currently visible detail View, you can use the GridView.GetVisibleDetailView method instead of the GetDetailView method.

Read the following help topics for detailed information: Master-Detail Relationships, Working with Master-Detail Relationships in Code.


Detail pattern Views do not contain data and they are never displayed within the Grid Control. Do not use the GetDetailView method for these Views. The GetDetailView method can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which the user interacts at runtime.

The code sample below illustrates how to add a custom editor to a detail view.

using DevExpress.XtraEditors.Repository;
using DevExpress.XtraGrid.Views.Grid;


private void gridView1_MasterRowExpanded(object sender, DevExpress.XtraGrid.Views.Grid.CustomMasterRowEventArgs e){
    GridView masterView = sender as GridView;
    int visibleDetailRelationIndex = masterView.GetVisibleDetailRelationIndex(e.RowHandle);
    GridView detailView = masterView.GetDetailView(e.RowHandle, visibleDetailRelationIndex) as GridView;
    RepositoryItemComboBox cBox = new RepositoryItemComboBox();
    cBox.Items.AddRange(new string[] { "A", "B", "C", "D" });
    detailView.Columns["Col2"].ColumnEdit = cBox;
