请教一个关于treeview控件和contextmenu一起使用的问题。
我的意思是这样的，把treeview控件和contextmenu一起使用，要实现的功能是这样的：当用户点击treeview的不同节点时（任何节点）弹出不同的菜单。不知道有那位高人知道怎么做，请赐教！谢谢。 --------------------编程问答-------------------- 在treeview的afterselect事件中写
if(选中节点A)
treeview.ContextMenu = contextMenuA;
else if(选中B)
treeview.ContextMenu = contextMenuB;
else
treeview.ContextMenu = contextMenuC; --------------------编程问答-------------------- private void trHistory_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
if (node != null)
{
nodeNumber = NodeLevel(e.Node).ToString();
ContextMenu popUpMenu = new ContextMenu();
switch (nodeNumber)
{
case "0":
popUpMenu.MenuItems.Add("受領追加", new EventHandler(Add_Click));
break;
case "1":
popUpMenu.MenuItems.Add("修正", new EventHandler(Change_Click));
popUpMenu.MenuItems.Add("症例情報", new EventHandler(Case_Click));
popUpMenu.MenuItems.Add("MedDRAコーディング", new EventHandler(MedDRA_Click));
popUpMenu.MenuItems.Add("製造販売後評価追加", new EventHandler(Add_Click));
break;
case "2":
popUpMenu.MenuItems.Add("修正", new EventHandler(Change_Click));
popUpMenu.MenuItems.Add("安全部報告追加", new EventHandler(Add_Click));
break;
case "3":
popUpMenu.MenuItems.Add("修正", new EventHandler(Change_Click));
break;
default:
break;
}
trHistory.ContextMenu = popUpMenu;
}
}
private int NodeLevel(TreeNode n)
{
int treeNodeCount = 0;
while (!(n.Parent == null))
{
n = n.Parent;
treeNodeCount += 1;
}
return treeNodeCount;
} --------------------编程问答-------------------- 好啊 谢谢
补充：.NET技术 , C#
