[strong1333]

怎么在点treeview控件中的项时，在listview控件中自动读出选中项的内容？？

[strong1333]

饿，还有个问题，怎么给你们加分

 private void PopulateRootLevel()
    {
        string connectionString = ConfigurationManager.ConnectionStrings["MySqlProviderConnection"].ConnectionString;
        SqlConnection objConn = new SqlConnection(connectionString);
        SqlCommand objCommand = new SqlCommand(@"select DepartmentID,DepartName,(select count(*) FROM Accounts_Department WHERE ParentDepartID=sc.DepartmentID) childnodecount FROM Accounts_Department sc where ParentDepartID=0", objConn);
        SqlDataAdapter da = new SqlDataAdapter(objCommand);
        DataTable dt = new DataTable();
        da.Fill(dt);
        PopulateNodes(dt, TreeView1.Nodes);
    }

    private void PopulateSubLevel(int parentid, TreeNode parentNode)
    {
        string connectionString = ConfigurationManager.ConnectionStrings["MySqlProviderConnection"].ConnectionString;
        SqlConnection objConn = new SqlConnection(connectionString);
        SqlCommand objCommand = new SqlCommand(@"select DepartmentID,DepartName,(select count(*) FROM Accounts_Department WHERE ParentDepartID=sc.DepartmentID) childnodecount FROM Accounts_Department sc where ParentDepartID=@ParentDepartID", objConn);
        objCommand.Parameters.Add("@ParentDepartID", SqlDbType.Int).Value = parentid;
        SqlDataAdapter da = new SqlDataAdapter(objCommand);
        DataTable dt = new DataTable();
        da.Fill(dt);
        PopulateNodes(dt, parentNode.ChildNodes);
    }


    protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e)
    {
        PopulateSubLevel(Int32.Parse(e.Node.Value), e.Node);
    }

    private void PopulateNodes(DataTable dt, TreeNodeCollection nodes)
    {
        foreach (DataRow dr in dt.Rows)
        {
            TreeNode tn = new TreeNode();
            tn.Text = dr["DepartName"].ToString();
            tn.Value = dr["DepartmentID"].ToString();
            tn.NavigateUrl = "departmentMain.aspx?id=" + dr["DepartmentID"].ToString();//框架实现，左边的treeview传值到右边的listview
            tn.Target = "content";
            nodes.Add(tn);

            //If node has child nodes, then enable on-demand populating
            tn.PopulateOnDemand = ((int)(dr["childnodecount"]) > 0);
        }
    }

在TreeView1_SelectedNodeChanged(object sender, EventArgs e)这个事件中，用TreeView1.SelectedValue.ToString();把选中的值得到，然后增加到listview中就可以

楼上很强啊，完整代码都出来了~~~厉害啊。。。。。

treeView1_NodeMouseClick事件
要想不刷新可用 ajax 或 框架

[jdbcodbc]

AJAX

[whyabc]

用NodeMouseClick事件就可以处理了！

[v_oneforever]

SelectedNodeChanged
TreeView1.SelectedValue.ToString();
ListView.add
即可
