TreeView 用法（有代码）（asp.net）

private void BindGrid()
{
DataTable mytable = menuTableBll.GetAllList().Tables[0]; //获取数据
CreateTree(mytable, TreeView1.Nodes, "0");
}
private void CreateTree(DataTable dtNodeSets, TreeNodeCollection node, string parent_id)
{
DataView dvList = new DataView(dtNodeSets);
dvList.RowFilter = "MeunParentId =" + parent_id;
TreeNode nodeTemp;
foreach (DataRowView dv in dvList)
{
nodeTemp = new TreeNode();
nodeTemp.Text = dv["MenuName"].ToString();
nodeTemp.Expanded = true;
nodeTemp.ToolTip = dv["MeunId"].ToString();
node.Add(nodeTemp);
CreateTree(dtNodeSets, nodeTemp.ChildNodes, dv["MeunId"].ToString());
}
}
