private void Form1_Load(object sender, EventArgs e)
        {
            richTextBox1.Text = "Enter your text here...";
            richTextBox1.Select(0, richTextBox1.TextLength);
            richTextBox1.SelectionBackColor = Color.Red;

        }

        private void richTextBox1_Enter(object sender, EventArgs e)
        {
            richTextBox1.Text = "";

        }

This will solve your problem, i guess at least if i got your point.

Error occurs from second forms method when i call it at constructor. I have a method for checkboxlist which is handling some items checkstate unchecked to checked. How can i prevent it or can i stop execution of checkboxlist itemcheck event at the secondform's constructor?

//second form's state alter method.. calling at constructor.
 void SelectedRoomBedTypes()
        {
            foreach (var item in bedtypes)
            {
                for (int i = 0; i < clstBedTypes.Items.Count; i++)
                {
                    BedTypes bt = clstBedTypes.Items[i] as BedTypes;
                    if (bt.ID == item.BedTypeID)
                    {
                        clstBedTypes.SetItemChecked(i, true);
                    }
                }
            }
        }

//clstBedTypes ItemCheck event


            BedTypes bt = (BedTypes )clstBedTypes.SelectedItem;
            if (e.NewValue == CheckState.Unchecked)
            {
                RoomBedType r = new RoomBedType();
                r.RoomID = _room.ID;//_room object from first form
                o.BedTypeID = bt.ID;
                MessageBox.Show(YatakTipIslemleri.OdayaGoreYatakTipSil(o));

            }
            else
            {
                OdaYatakTip o = new OdaYatakTip();
                o.OdaID = _oda.ID;
                o.YatakTipID = yt.ID;
                MessageBox.Show(BedTypeProc.SaveBedRoomTypeByRoom(o));

thanks.
