[Solved] Move to next cell on DataGridView not working when allowUserToAddRow is false in Windows Application

When press enter in cell while editing move to next cell and i have code to do that but is not work in last row.

I set allowUserToAddRow = false

        private DataGridViewCell dgvEndEditCell;
        private bool _EnterMoveNext = true;
        private bool isMovedByEnter { set; get; }
        [System.ComponentModel.DefaultValue(true)]
        public bool OnEnterKeyMoveNext
        {
            get
            {
                return this._EnterMoveNext;
            }
            set
            {
                this._EnterMoveNext = value;
            }
        }

        private void dataGridView1_SelectionChanged(object sender, System.EventArgs e)
        {
            if (this._EnterMoveNext && MouseButtons == 0)
            {
                if (this.dgvEndEditCell != null && dgvTranDetail.CurrentCell != null)
                {
                    if (dgvTranDetail.CurrentCell.RowIndex == this.dgvEndEditCell.RowIndex + 1 && dgvTranDetail.CurrentCell.ColumnIndex == this.dgvEndEditCell.ColumnIndex)
                    {
                        int iColNew;

                        int iRowNew;

                        if (this.dgvEndEditCell.ColumnIndex >= dgvTranDetail.ColumnCount - 1)
