请问:如何重绘DGV

Question

        private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            System.Drawing.Rectangle rectangle = new System.Drawing.Rectangle(e.RowBounds.Location.X,
                 e.RowBounds.Location.Y,
                 dataGridView1.RowHeadersWidth - 4,
                 e.RowBounds.Height);            TextRenderer.DrawText(e.Graphics, (e.RowIndex + 1).ToString(),
                dataGridView1.RowHeadersDefaultCellStyle.Font,
                rectangle,
                dataGridView1.RowHeadersDefaultCellStyle.ForeColor,
                TextFormatFlags.VerticalCenter | TextFormatFlags.Right);
        }        private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {            if (this.dataGridView1.Rows.Count != 0)
            {
                for (int i = 0; i < this.dataGridView1.Rows.Count; i += 2)
                {
                    this.dataGridView1.Rows[i].DefaultCellStyle.BackColor = System.Drawing.Color.Cyan;
                }
            }
        }
以上是我想加入的重绘函数.但我每次用新的DGV,都要加入这两个函数.有没有什么方法,可以使得自己以后直接使用DGV就会自动重绘这两个函数的方法.也就是说,能不能建成一个类,这个类直接包含了以上两个函数?俺不会,我想肯定是可以的,请详细说一下步骤.谢谢.

Answer 1

    你继承DGV写个控件  你重写这两个事件就行了
   
        protected override void OnDataBindingComplete(DataGridViewBindingCompleteEventArgs e)
        {
            base.OnDataBindingComplete(e);
             if (this.Rows.Count != 0)
            {
                for (int i = 0; i < this.dataGridView1.Rows.Count; i += 2)
                {
                    this.dataGridView1.Rows[i].DefaultCellStyle.BackColor = System.Drawing.Color.Cyan;
                }
            }        }

7L正解,新建一个类继承DataGridView,重载那两个函数就行了
