Add row number in datagridview in vb.net
提问by Brijesh Patel
I am developing Windows Application in Vb.Net. Now there is one form in which I want to print records displayed in the grid. There is a facility to sort grid by clicking on the cell header in the grid And that should be print as displayed in the grid.
我正在 Vb.Net 中开发 Windows 应用程序。现在有一种表格，我想在其中打印网格中显示的记录。通过单击网格中的单元格标题可以对网格进行排序，并且应该按照网格中的显示进行打印。
So I am little bit confuse about how to maintain the row number in the grid. I can take row number from DB initially when grid fill and assign data source. But when user clicks any cell header and sort that column then the row number is changed. At that time it is very difficult for me to maintain the row number.
所以我对如何维护网格中的行号有点困惑。我可以在网格填充和分配数据源时最初从数据库中获取行号。但是当用户单击任何单元格标题并对该列进行排序时，行号就会改变。当时我很难维护行号。
Can any one give me idea how to maintain row number in the grid?
谁能告诉我如何在网格中维护行号？
Thanks in advance.
提前致谢。

private void dgvUserDetails_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
using (SolidBrush b = new SolidBrush(dgvUserDetails.RowHeadersDefaultCellStyle.ForeColor))
{
e.Graphics.DrawString((e.RowIndex + 1).ToString(), e.InheritedRowStyle.Font, b, e.RowBounds.Location.X + 10, e.RowBounds.Location.Y + 4);
}
}
