Question

 hi friends this is my code but in this when i click on  my delete button(this is also present in TimerUserControl) ,TimerUserControl will delete from the panel control list and remaining all controls are repositioned from top to bottom ...and i am unable to catch the index position of deleted TimerUserControl


private void btnAddTimer_Click(object sender, EventArgs e)

        {

            TimerUserControl obj_TimerUserControl = new TimerUserControl();

            obj_TimerUserControl.Name = "Timer" + count;

            obj_TimerUserControl.Location = new Point(5, count * 200);

            obj_TimerUserControl.Size = new Size(540, 180);

            bodyPanel.Controls.Add(obj_TimerUserControl);

            obj.Add(obj_TimerUserControl);

            count++;

            MessageBox.Show(obj_TimerUserControl.Name.ToString());

        }

        private void bodyPanel_ControlRemoved(object sender, ControlEventArgs e)

        {

            

            TimerUserControl tim = (TimerUserControl)sender;

           

            int index = obj.IndexOf(tim);

            for (int i = index; i < obj.Count; i++)

            {

                obj[i].Location = new Point(5, i * 200 - 200);

            }
