一 DEV控件下的 gridview单元格操作

/// <summary>

        /// 在指定单元格里面画圆，写文字，修改外观(重绘数据时发生)
        /// </summary>
        void gvBoardInfo_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
        {
            if (e.Column == gvBoardInfo.Columns["id"] && e.RowHandle > -1)
            {
                float x = e.Bounds.Location.X;
                float y = e.Bounds.Location.Y;

e.Graphics.FillEllipse(Brushes.Red, x, y, 10, 10);

e.Graphics.DrawString(font, brush, x, y);

e.Appearance.ForeColor = Color.Red;
}

}

        /// <summary>
        /// 使单元格内容居中(重绘数据时发生)
        /// </summary>
        void gvBoardInfo_RowCellDefaultAlignment(object sender, DevExpress.XtraGrid.Views.Base.RowCellAlignmentEventArgs e)
        {
            e.HorzAlignment = HorzAlignment.Center;
        }

        /// <summary>
        /// 修改指定单元格文字，背景等(重绘数据时发生)
        /// </summary>
        void gvBoardInfo_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
        {
            if (e.Column == gvBoardInfo.Columns["id"])
           {

           }
        }

二原生态 gridview 单元格操作

dgv.RowsDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter; //使内容居中

void DGV_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)

{

if (e.RowIndex > -1 && e.ColumnIndex > -1)

{

e.PaintBackground(e.CellBounds, false);

e.Graphics.FillEllipse(Brushes.Red, e.CellBounds);

e.Graphics.DrawString(e.RowIndex.ToString() + e.ColumnIndex.ToString(), this.Font, Brushes.Black, new PointF(x,y));

e.Handled = true;

}}
