TabPage mouse event handler not happening

Christ Kennedy 41

I'm writing a TabPage_MyOwn class that inherits MS TabPage
and the MouseMove, MouseUp and MouseDown event handlers are not happening.

    public class ck_TabPage : TabPage   
        {  
            Point ptZer0 = new Point(0, 0);  
  
            public ck_TabPage()  
            {  
                tmrGrab_Move.Interval = 100;  
                tmrGrab_Move.Tick += TmrGrab_Move_Tick;  
  
                MouseMove += Ck_TabPage_MouseMove;  
                MouseDown += Ck_TabPage_MouseDown;  
                MouseUp += Ck_TabPage_MouseUp;  
  
            }  
              
            private void Ck_TabPage_MouseUp(object sender, MouseEventArgs e)  
            {  
                tmrGrab_Intent.Enabled = false;  
                Grab = false;  
            }  
  
            private void Ck_TabPage_MouseDown(object sender, MouseEventArgs e)  
            {  
                tmrGrab_Intent.Enabled = e.Y < 15;  
            }  
  
            private void Ck_TabPage_MouseMove(object sender, MouseEventArgs e)  
            {  
                tmrGrab_Intent.Enabled = false;  
                ptGrab = new Point(e.X, e.Y);  
            }  
}

I have several of these, they're in their TabControllers doing what they do. But none of these event handlers are happening.

@Christ Kennedy , Welcome to Microsoft Q&A, based on my test, I find that all the mouse events are triggered for me(like the following code). It may be related to your specific code in the event.

 private void Ck_TabPage_MouseUp(object sender, MouseEventArgs e)  
        {  
            //tmrGrab_Intent.Enabled = false;  
            //Grab = false;  
            Console.WriteLine("up");  
        }  
  
        private void Ck_TabPage_MouseDown(object sender, MouseEventArgs e)  
        {  
            //tmrGrab_Intent.Enabled = e.Y < 15;  
            Console.WriteLine("down");  
        }  
  
        private void Ck_TabPage_MouseMove(object sender, MouseEventArgs e)  
        {  
            //tmrGrab_Intent.Enabled = false;  
            //ptGrab = new Point(e.X, e.Y);  
            Console.WriteLine("move");  
        }

Therefore, Could you provide some code about how to and where you define some controls (etc. tmrGrab_Move,tmrGrab_Intent)?

hi, thanks for your interest.
my problem was dealing with 'TabPages' and their mouse events. I still don't know why they have events when they are not triggered but the events given in the code above have never worked -> with my TabPage objects.
I've resorted to the TabControl events and, since the TabSelected must be the one beneath the mouse, send the TabControl events to the tbCtrl.TabSelected.MouseEventHander() event handlers written for the TabPages (or just do what they're going to do in the TabControl event handler)
