</syncfusion:GridViewDefinition.DataGrid>
</syncfusion:GridViewDefinition>
</syncfusion:SfDataGrid.DetailsViewDefinition>
</syncfusion:SfDataGrid>

void detailsViewGrid_AutoGeneratingColumn(object sender, AutoGeneratingColumnArgs e)

void dataGrid_AutoGeneratingRelations(object sender, AutoGeneratingRelationsArgs e)
{
e.GridViewDefinition.DataGrid.AutoGeneratingColumn += DataGrid_AutoGeneratingColumn;
