我尝试以编程方式将2个dataTable编码为Master-Detail网格。不幸的是一周，我尝试谷歌解决方案，我仍然失败。 我使用c＃和DevExpress，我设法将额外的Level1设置为gridView2。 主要是gridview1和gridContorl1下的所有内容。下面是我做的代码，并寻求建议希望我管理我的实验计划的最后一步。 主表是tableSalesOrder＆amp;详细故事是tableDetail。如何关联tableSalesOrder和tableDetail，当选择tableSalesOrder ItemCode时，tableDetail将只显示Master-Detail视图下的ItemCode
private void btnLoadSO_Click(object sender, EventArgs e)
{
LoadOutstandingSO();
LoadDetailDS();
gridControl1.DataSource = tableSalesOrder;
}
private void LoadOutstandingSO()
{
if (tableSalesOrder == null)
tableSalesOrder = new DataTable("dtSO");
else
tableSalesOrder.Clear();

要按给定主行查找详细信息行，您需要在数据集中的这些表之间添加relationship。该关系定义了详细行与其主行关联的列。
如果详细级别名称与关系名称匹配，则XtraGrid可以自动从关系中检索详细信息视图的数据。您可以使用level designer或programmatically分配关卡名称。
此外，如果DataSet具有关系且ShowOnlyPredefinedDetails选项设置为 false ，则XtraGrid可以自动填充详细级别。
