VS2008 treeview问题

在VS2008 VB的环境下 treeview控件的节点怎么用代码加上，包括父级和子级的 最好给个例子

Answer 1

TreeNode tnP = new TreeNode();//创建一个父节点
tnP.Text = "父";

TreeNode tnC1 = new TreeNode();//创建一个子节点并添加到父节点中
tnC1.Text = "子1";
tnP.Nodes.Add(tnC1);
TreeNode tnC2 = new TreeNode();
tnC2.Text = "子2";
tnP.Nodes.Add(tnC2);

treeView1.Nodes.Add(tnP);//把父节点添加到TreeView控件中

追问

可以了 非常感谢

Answer 2

private void InitData(int bomSID)
{
BomManage bmManage = new BomManage();
MM_BomMain bm = bmManage.GetBomMain(bomSID);

TreeNode rootNode = new TreeNode();
rootNode.Text = bm.CInvCode + " - " + (new InventoryInfo()).GetInventoryName(bm.CInvCode) + " (" + bm.VisionNumber + ")";
rootNode.Value = "-1";
rootNode.NavigateUrl = "#";
PopulateTreeView(bmManage, bomSID, rootNode, true);
this.tvBom.Nodes.Add(rootNode);
}

private void PopulateTreeView(BomManage bmManage,int parentId, TreeNode parentNode, bool bFlag)
{
DataView dv = bmManage.GetNodes(parentId, bFlag).DefaultView;
foreach (DataRowView drv in dv)
{
TreeNode myNode = new TreeNode(drv["InvCode"].ToString() + " - " + (new InventoryInfo()).GetInventoryName(drv["InvCode"].ToString()) + " [" + drv["Quantity"].ToString() + "]");
myNode.Value = drv["SID"].ToString();
myNode.NavigateUrl = "#";
parentNode.ChildNodes.Add(myNode);
PopulateTreeView(bmManage, Convert.ToInt32(drv["SID"].ToString()), myNode, false);
}
}
