dev gridcontrol 父级关系嵌套 隐藏做为关系映射字段

如何隐藏做为关系映射字段（BomDetailNoID)

Answer 1

对主表的MasterRowExpanded事件编程。代码大致如下:
void gridView_MasterRowExpanded(object sender, CustomMasterRowEventArgs e)
{
GridView gridViewMaster = sender as GridView;
GridView gridViewDetail = gridViewMaster.GetDetailView(e.RowHandle, e.RelationIndex) as GridView;
gridViewDetail.BeginUpdate();
gridViewDetail.Columns["BomDetailNoID"].Visible = false;
gridViewDetail.Columns["BomDetailNoID"].OptionsColumn.ShowInCustomizationForm = false;
gridViewDetail.EndUpdate();
}

gridControl 的默认 GridView

 gridViewMaster.GetDetailView(e.RowHandle, e.RelationIndex) as GridView;
返回空对象
