数据库动态形成navBarControl

int i = 0;
foreach (DataRow dr in drs)

DevExpress.XtraNavBar.NavBarGroup Nbg = new DevExpress.XtraNavBar.NavBarGroup();

if (i ==1) Nbg.Expanded = true;//打开第一层
navBarControl1.Groups.Add(Nbg);

///单击事件

string ls_form;
ls_form = e.Link.Item.Name.Trim();
//防止一个窗口打开多次
if (Application.OpenForms[ls_form] != null)
{
Application.OpenForms[ls_form].Activate();
return;
}
string assemblyName = (ls_form.Trim().Split('.'))[0];
Form frm = (Form)System.Reflection.Assembly.Load(assemblyName).CreateInstance(ls_form);
frm.Show();
}
catch (Exception ee)
{
MessageBox.Show(ee.Message);
return;
}
}
代码是从网上复制的 有点不明白的是这句 dt = GetSubList();各位大神帮忙看看 数据库动态形成navBarControl --------------------编程问答-------------------- 你没复制全吧，GetSubList函数你没复制过来
这应该是查询下级列表的并返回下级列表的DataTable的方法 --------------------编程问答-------------------- 能否帮忙编程一下？？？？ --------------------编程问答-------------------- 鬼才知道里面逻辑是什么？
怎么帮你写
补充：.NET技术 , C#
