DataGridView绘制行号

  在MS DataGridView行的最前面显示行号，类似于Excel中的行号一样。实际上就是在DataGridView.RowPostPaint事件中重绘文本。

  

        //在行的最前面处,手工绘制显示行号
        private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            Rectangle rectangle = new 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);
        }

    

   下面的代码实现DataGridView.Column的数据绑定，设置的是列的DataPropertyName属性

        private void mySql_FillMOColorSize(string AMONo)
        {
            string vSql = string.Format(cSql_FillMOColorSize,AMONo,this.cmbSizeName.Text.Trim());
            TSunVKBHelper.mmFillDataTable(this.m_tblMOColorSize,vSql) ; 

            this.dataGridView1.SuspendLayout();
            try
            {
                this.dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;
                this.dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None;
                this.gcMONo.DataPropertyName = "MONo";
                this.gcColorName.DataPropertyName = "ColorName";
                this.gcSizename.DataPropertyName = "SizeName";
                this.gcQty.DataPropertyName = "Qty";
                this.gcColorNo.DataPropertyName = "ColorNo";
                this.dataGridView1.AutoGenerateColumns = false;  //[BugHere][MustAdd]
                this.dataGridView1.DataSource = this.m_tblMOColorSize;
            }
            finally
            {
                this.dataGridView1.ResumeLayout();
            }
            //this.dataGridView1.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader);
        }
