The event to stop the form closing is on the Form and is called FormClosing.

You can validate your informations in there, and if there is a problem, simply set the e.Cancel parameter to True to prevent the form going on with the closing operation.

It has DropItemClosed but no DropItemClosing event.
If you add these events to your code - you can keep the menu open till the mouse leaves:

  bool MouseIn = false;

        private void contextMenuStrip1_Closing( object sender , ToolStripDropDownClosingEventArgs e )
            if ( MouseIn )
                e.Cancel = true;

        private void contextMenuStrip1_MouseEnter( object sender , EventArgs e )
            MouseIn = true;

        private void contextMenuStrip1_MouseLeave( object sender , EventArgs e )
            MouseIn = false;

Open in new window

Thank for reply but there is no closing properties for that menulist..
Please post the code that creates the object you are referring to, this will let us know the type of control you are using. As "menulist" is not a control.
