两个Gridview之间如何传值？

Question

我想从Gridview1中选择一些数据
先存放到Gridview2中然后进行保存到数据库
请问我如何实现？现在可以取到Gridview1中的值 但是无法成功放到Gridview2中？
求解？？？

Answer 1

取出 gridview数据
Gridview2添加一行，重新绑定
DataSet ds；
  DataRow dr = ds.Tables[0].NewRow();
  dr[0] = System.Int32.Parse("0");
  dr[1] = "";
  dr[2] = "";
  ds.Tables[0].Rows.InsertAt(dr, 0);  Gridview1.DataSource = ds;
  Gridview1.DataBind();   
 
模版列编辑
或GridView1.ShowFooter = true;
 在Footer中添加TextBox等

Answer 2

foreach (GridViewRow gvrow in GridView控件)
        {
           
        }

Answer 3

  protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        //gridview.rows[selrow].cols[selcol].tostring(). 
        //string s=GridView3.SelectedRow.Cells[0].Text.Trim();
        //string ProductsName = e.Row.Cells[1].Text;        //string Uints = e.Row.Cells[2].Text;        string Spec = GridView2.DataKeys[e.RowIndex]["Spec"].ToString();
        string ProductsName = GridView2.DataKeys[e.RowIndex]["ProductsName"].ToString();
        string Uints = GridView2.DataKeys[e.RowIndex]["ProductsUints"].ToString();
return;
    }
这样取值 然后 用你方法如何实现？？？？
