Answer 1

Won't something like this work for you?

    class ToolStripItemEx : ToolStripItem
    {
        protected override bool DismissWhenClicked
        {
            get
            {
                return true;
            }
        }
    }

In the get statement you could specify when to be dismissed and when not.

Will this make the ToolStripItem Visible after I click it?
I want to process the click event, and keep it visible.
Thank you. 
 

Answer 3

Hi,

You can write this code to CheckedChanged event of ToolStipMenuItem that you want to keep visible after clicked.

        private void bToolStripMenuItem_CheckedChanged(object sender, EventArgs e)
        {
            ((ToolStripMenuItem)bToolStripMenuItem.OwnerItem).ShowDropDown();
            
        }

Or you can develop your custom ToolStripMenuItemClass like following.

   public class MyToolStripMenuItem : ToolStripMenuItem
    {
        protected override void OnCheckedChanged(EventArgs e)
        {

            base.OnCheckedChanged(e);
            ((ToolStripMenuItem)this.OwnerItem).ShowDropDown();
        }
    }

Answer 5

In this way, there is one problem,
after I click a 4th level menu item, the item and its parent( a 3rd level menu item) are visible,
while the 2nd level menu item is invisible now.
Shall I call the ShowDropDown method recursively to the root? 
 

Answer 6

Hi,

You might need to call the method on every ownerItem:

            ToolStripMenuItem ts = (ToolStripMenuItem)bToolStripMenuItem.OwnerItem;
            while (ts!= null)
            {
                ts.ShowDropDown();
                //Console.WriteLine(ts.Name);
                ts = (ToolStripMenuItem)ts.OwnerItem;            
 
            }
