这个是在网上找的一片文章，自己试着调试了一下，但并未调试成功，以后有时间了在调试吧！大家谁调试出来也可以发布出来分享。

protected void GridView1_RowCreated( object sender, GridViewRowEventArgs e)
     ... {
         if (e.Row.RowType == DataControlRowType.DataRow)
         ... {
             if (e.Row.FindControl("Button1") != null )
             ... {
                Button btn = (Button)e.Row.FindControl("Button1");
                btn.Click += new EventHandler(btn_Click);
            }
        }
    }

     private void btn_Click( object sender, EventArgs e)
     ... {
        Button btn = (Button)sender;
        GridViewRow gvr = (GridViewRow)btn.Parent.Parent;
         string pk = GridView1.DataKeys[gvr.RowIndex].Value.ToString();

         this .Label1.Text = pk;

<asp:TemplateField>
           <ItemTemplate>
                   <asp:Button    ID="Button1"    runat="server"    CommandName="MyCommand"    Text="Button"    />
           </ItemTemplate>
   </asp:TemplateField>
   ===============================================
   protected    void    GridView1_RowCommand(object    sender,    GridViewCommandEventArgs    e)
   {
           if    (e.CommandName    ==    "MyCommand")
           {
                  Button button = (Button)e.CommandSource;
                  GridViewRow row = (GridViewRow)button.Parent.Parent;
                  string a = row.Cells[1].Text.ToString();// 获得第一个单元格的值
                  string    b    =    this.GridView1.DataKeys[row.DataItemIndex].Values[0];// 获得 DataKeys 的值
           }
   }
