WPF TreeView问题~急~

Question

TreeView结构如下:
|--A
   |--A1
      |--AA1
|--B
   |--B1
      |--BB1
         |--AA1
我要在选中AA1时,将其AA1传出来进行数据查询
怎样判断传出来是A1下的AA1还是B1下的AA1呀
以前在WINFORM中我是用treeview.SelectNode.level
取得其视图的深度来判断的,在WPF中如何做呀
请高手指点~~急,在线等~~
顶的也散分~~

Answer 1

有呀,可写了半天弄不出来呀,以前在WINFORM中是这样的:switch (Menu_TV.SelectedNode.Level.ToString())
                    {
                        case "4"://如果选中的节点深度为3,则从其父节点的父节点开始进行查询,如:主卧-墙面-油漆-立邦
                            {
                                wareSql = "Select Ware_Id,Ware_PicMinUrl From Me_Ware Where Ware_ColType='" + Menu_TV.SelectedNode.Parent.Parent.Parent.Text.ToString() + "'";
                                wareSql += " and Ware_ColWName='" + Menu_TV.SelectedNode.Parent.Parent.Text.ToString() + "' and Ware_ColWType='" + Menu_TV.SelectedNode.Parent.Text.ToString() + "'";
                                wareSql += " and Ware_ColWTName='" + Menu_TV.SelectedNode.Text.ToString() + "'";
 
                                break;
                            }
                        case "3"://如果选中的节点深度为3,则从其父节点的父节点开始进行查询,如:主卧-墙面-油漆
                            {
                                wareSql = "Select Ware_Id,Ware_PicMinUrl From Me_Ware Where Ware_ColType='" + Menu_TV.SelectedNode.Parent.Parent.Text.ToString() + "'";
                                wareSql += " and Ware_ColWName='" + Menu_TV.SelectedNode.Parent.Text.ToString() + "' and Ware_ColWType='" + Menu_TV.SelectedNode.Text.ToString() + "'";
 
                                break;
                            }
                        case "2"://如果选中的节点深度为2,则从其父节点开始进行查询,如:主卧-顶面
                            {
                                wareSql = "Select Ware_Id,Ware_PicMinUrl From Me_Ware Where Ware_ColType='" + Menu_TV.SelectedNode.Parent.Text.ToString() + "'";
                                wareSql += " and Ware_ColWName='" + Menu_TV.SelectedNode.Text.ToString() + "'";
                                                                
                                break;
                            }
                        case "1"://如果选中的节点深度为1,则从其本身开始进行查询,如:饰品装饰-地毯
                            {
                                wareSql = "Select Ware_Id,Ware_PicMinUrl From Me_Ware Where Ware_ColType='" + Menu_TV.SelectedNode.Text.ToString() + "'";
 
                                break;
                            }
                    }

没用过wpf的，不过和２００５的应该差不多吧，给你参考下
 protected void TreeViewType_SelectedNodeChanged(object sender, EventArgs e)
    {
        TreeView tree = sender as TreeView;
        if (tree != null)
        {
            TreeNode node = tree.SelectedNode;
            if (node != null)
            {
                if (node.Value == "-1")
                    model = 1;
                else if (node.Parent != null && node.Parent.Value == "-1")
                    model = 2;
                else if (node.Parent != null && node.Parent.Value == "-2")
                    model = 3;
                else
                {
                    TreeNode pNode = node;
                    string strValue = null;
                    do
                    {
                        strValue = pNode.Value;
                        pNode = pNode.Parent;
                    }
                    while (pNode.Value != "-1");                    int.TryParse(strValue, out year);
                    model = 4;
                }
            }
            this.MyGridView1.OnBind();
        }
    }
