C#TreeView右键菜单
⽅法⼀：
在winform中，添加⼀个contextMenuStrip1，设置TreeView的属性ContextMenuStrip为contextMenuStrip1，并为这个contextMenuStrip1添加⼏个菜单项，点击每个菜单项，实现其click事件，然后添加treeivew的nodemouseclick事件，类似如下代码：
//右键菜单
private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
if (e.Button != MouseButtons.Right) return;
if (e.Node.Parent == null || e.Node == null) return;
treeView1.SelectedNode = e.Node;
contextMenuStrip1.Show(tv_Roots, e.X, e.Y);
}
  void contextMenuStripItem_Click(object sender, EventArgs e)//编辑飞⾏段
{
}
⽅法⼆：不同节点对应不同的右键菜单（摘⾃wwwblogs/imihiroblog/archive/2012/06/02/2531949.html）
private void tvOneRoot_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
if (e.Button != MouseButtons.Right) return;
if (e.Node == null) return; //⽆节点
if (e.Node.Level == 0) return;
int nodeType = GetNodeTypeByGuid(e.Node.Name);
tvOneRoot.SelectedNode = e.Node;
InitcmsOneRout(nodeType);
cmsOneRout.Show(tvOneRoot, e.X, e.Y);
}menustrip和toolstrip
///<summary>
///初始化cmsOneRoot 从nodetype
///</summary>
///<param name="nodetype"></param>
private void InitcmsOneRout(int nodetype)
{
cmsOneRout = new ContextMenuStrip();
if (nodetype == -1)
{
ToolStripMenuItem tmiEditRoutStation = new ToolStripMenuItem("编辑飞⾏站点");
tmiEditRoutStation.Click += new EventHandler(tmiEditRoutStation_Click);
cmsOneRout.Items.Add(tmiEditRoutStation);
ToolStripMenuItem tmiMoveRouteStation = new ToolStripMenuItem("更改位置");
tmiMoveRouteStation.Click += new EventHandler(tmiMoveRouteStation_Click);
cmsOneRout.Items.Add(tmiMoveRouteStation);
ToolStripMenuItem tmiDeleRouteStation = new ToolStripMenuItem("删除飞⾏站点");
tmiDeleRouteStation.Click += new EventHandler(tmiDeleRouteStation_Click);
cmsOneRout.Items.Add(tmiDeleRouteStation);
}
else if (nodetype == 0)
{
ToolStripMenuItem tmiEditRout = new ToolStripMenuItem("编辑飞⾏段属性");
tmiEditRout.Click += new EventHandler(tmiEditRout_Click);
cmsOneRout.Items.Add(tmiEditRout);
ToolStripMenuItem tmiDeleteRout = new ToolStripMenuItem("删除飞⾏段");
tmiDeleteRout.Click += new EventHandler(tmiDeleteRout_Click);
cmsOneRout.Items.Add(tmiDeleteRout);
}
else if (nodetype == 1)
{
}
else if (nodetype == 2)
{
}
else
{
}
}
void tmiEditRout_Click(object sender, EventArgs e)//编辑飞⾏段
{
string routId = tvOneRoot.SelectedNode.Name;
RouteParameter rp = GetRouteParaByGuid(routId);
FrmPointProperty frm = new FrmPointProperty(rp, 0, 1);
frm.OnRoutInfoUpdated += new FrmPointProperty.DelegateRouteInfoUpdated(frm_OnRoutInfoUpdated);            frm.ShowDialog();
}
