如何获取datagridview行号和列号？

Answer 1

获取datagridview的行号和列号的方法：

private void dataridView1_Cellnter(object sender, DatGridViwCellEventArgs e)

{

iTag = (int)this.Tag;

//if (iTag == 4)

//{

//    if (e.ColumnIndex ==3)

//        MessageBox.Show("该列为只读列", "提示信息", MesageBoxButtons.OK,

MesageBoxIcon.Inforation);

//}

//获取当前单元格行号和列号

string rowIndex = e.RoIndex.ToString();

string colIdex = e.ColumnIdex.ToString();

}

Answer 2

winform中让datagridview自动显示行号代码如下：
private void gvPurchaseOrder_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
using (SolidBrush b = new SolidBrush(this.gvPurchaseOrder.RowHeadersDefaultCellStyle.ForeColor))
{
e.Graphics.DrawString(Convert.ToString(e.RowIndex + 1, CultureInfo.CurrentUICulture),
e.InheritedRowStyle.Font, b, e.RowBounds.Location.X + 20, e.RowBounds.Location.Y + 4);
}
}
