GridView排序、分页

protected void gvBookTaxis_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (gvBookTaxis.PageIndex == 0)//判断是否是从第一页开始
        {
            if (e.Row.RowIndex != -1)   //判断GridView控件中是否有值
            {
                int id = e.Row.RowIndex + 1;//将当前行的索引加上一赋值给变量id
                e.Row.Cells[0].Text = id.ToString();//将变量id的值传给GridView控件的每一行的单元格中
            }
        }
        else
        {
            if (e.Row.RowIndex != -1)//否则就用当前页乘以每页显示条数，再加1
            {
                int id = (gvBookTaxis.PageIndex * 每页显示条数) + e.Row.RowIndex + 1;
                e.Row.Cells[0].Text = id.ToString();
            }
        }

}

 

    protected void gvBookTaxis_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        gvBookTaxis.PageIndex = e.NewPageIndex;
        gvBookTaxis.DataBind();
    }
