c# - Load multiple tables into Gridview and Save in DB by ASP.NET C#

Question

There is a hierarchy (parent-child) relationship between three Tables A > B > C in Database ..

I need to load some fields from each table into GridView and change data then save it back into the Database by ASP.NET with C# with ADO.NET
But I need a little sample code, I searched but couldn't find any thing for this scenario ..

Any help, thanks.

下面是一个很好的链接。
这个想法很简单，用户gridview events还是data-source要显示和更新数据库。

您可以遍历整个 GridView，并从每一行获取数据。然后将这些数据（每一行）逐行插入到测试表中：

foreach (GridViewRow gvr in GridView1.Rows)
{
    string data1 = gvr.Cells[0].Text;    
      //get data from BoundField in each row
    string data2 = ((Label)gvr.FindControl("Label1")).Text;    
      //get data from control in TemplateField in each row
    SqlCommand cmd = new SqlCommand("insert_sql", conn);   
      //generate insert sql using above data
    cmd.ExecuteNonQuery();
}
