datagridview如何在前面增加一列序号

[ji_vicky]

我通过SQL的select进行查询，查询出来的内容设成一个datatable
我的datagridview的datasource连接这个datatable
我现在需要在DataGridView的最前面加一列序号， 是自动从1开始编码的，请问我需要如何完善这个功能呢？

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{ if (e.Row.RowIndex >= 0)
{
e.Row.Cells[0].Text = Convert.ToString(e.Row.DataItemIndex + 1);
}
}

我的不是vs2003而是2005

[ClsData]

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowIndex != -1)
{
int id = e.Row.RowIndex + 1;
e.Row.Cells[1].Text = id.ToString();
}

}

[ClsData]

前台
<asp:BoundField HeaderText="NO." ReadOnly="True">
<ItemStyle Width="5%" HorizontalAlign="Center" />
<HeaderStyle Height="30px" />
</asp:BoundField>

这是第二列，第一列示隐藏的id

假设你原来取出的DataTable为dt

DataTable ndt = new DataTable();
DataColumn dc = new DataColumn();
dc.ColumnName = "序号";
dc.AutoIncrement = true;
dc.AutoIncrementSeed = 1;
dc.AutoIncrementStep = 1;
ndt.Columns.Add(dc);
ndt.Merge(dt);

dataGridView1.DataSource = ndt;

HeaderText="NO."

DataGridViewCheckBoxColumn column = new DataGridViewCheckBoxColumn();
{
column.HeaderText = "flag";
column.Name = "flag";

column.CellTemplate = new DataGridViewCheckBoxCell(false);
column.TrueValue = 1;
column.FalseValue = 0;
column.Width = 25;
column.IndeterminateValue = 1;
this.dataGridView1.Columns.AddRange(new DataGridViewColumn[] {column});
}
