            if (textBox_search_word.Text == string.Empty)
            {
               MyBindingSource.RemoveFilter();
            }
            else
            {
                MyBindingSource.Filter = string.Format("Name LIKE '*{0}*'", textBox_search_word.Text);
                MydataGridView.DataSource = MyBindingSource;
            }
