首先代码生成人菜单
private void listView_MouseClick(object sender, MouseEventArgs e)
{
if (Program.Usergroup == "工程部" && e.Button == MouseButtons.Right && this .listView .SelectedItems .Count >0)
{
ContextMenuStrip cms = new ContextMenuStrip();
cms.Name = "cms";
cms.Items.Add("查看原始目录", null);
cms.Items.Add("修改非标信息", null);
this.ContextMenuStrip = cms;
cms.Show(listView,e.Location);
}
}
问题：
开始右键是没有菜单的，然后在Listview右键一项后出现菜单，然后不管是在Listview空白的地方还是窗体的任何一个地方右键都会出现这个菜单，好郁闷啊，要怎样解决这个菜单只能在Listview里面选中行的时候右键才出现？
补充一个问题，可不可以图标从ImageList里面添加，代码怎么写？
解决方案

private ListViewItem GetItemFromPoint(ListView listView, Point mousePosition)
{
// translate the mouse position from screen coordinates to
// client coordinates within the given ListView
Point localPoint = listView.PointToClient(mousePosition);
return listView.GetItemAt(localPoint.X, localPoint.Y);
}
判断GetItemFromPoint!=null
{
// translate the mouse position from screen coordinates to
// client coordinates within the given ListView
Point localPoint = listView.PointToClient(mousePosition);
return listView.GetItemAt(localPoint.X, localPoint.Y);
}
判断GetItemFromPoint!=null

触发事件 前面先判断能否选中项 没选就return
