GridView里面的内嵌的服务器控件如LinkButton如何传值？

      GridView里面的内嵌的服务器控件如LinkButton如何传值到LinkButton 事件中

< asp:GridView ID = " GridView1 "  runat = " server "  AllowPaging = " True "  AutoGenerateColumns = " False "
    CellPadding = " 4 "  DataKeyNames = " Code "  DataSourceID = " ObjectDataSource1 "  ForeColor = " #333333 "
    GridLines = " Vertical "  Width = " 100% "  PageSize = " 6 " >
     < FooterStyle BackColor = " #5D7B9D "  Font - Bold = " True "  ForeColor = " White "   />
     < Columns >
         < asp:BoundField DataField = " publishType "  HeaderText = " 杂志类型 "   >
             < ItemStyle HorizontalAlign = " Center "   />
         </ asp:BoundField >
         < asp:BoundField DataField = " magCode "  HeaderText = " 杂志编号 "   />
         < asp:BoundField DataField = " Name "  HeaderText = " 杂志名称 "   />
         < asp:BoundField DataField = " Volumn "  HeaderText = " 刊数 "  SortExpression = " Volumn "   />
         < asp:BoundField DataField = " Code "  HeaderText = " 期刊编号 "  SortExpression = " Code "   />
         < asp:CheckBoxField DataField = " CanPublish "  HeaderText = " 发布 "   />
         < asp:BoundField DataField = " Category "  HeaderText = " 所属分类 "   />
         < asp:BoundField DataField = " Author "  HeaderText = " 作者 "   />
          < asp:BoundField DataField = " Brief "  HeaderText = " 摘要内容 "   />
           < asp:TemplateField ShowHeader = " False " >
             < ItemStyle HorizontalAlign = " Center "  Width = " 40px "   />
             < ItemTemplate >  
                 < asp:HyperLink ID = " HyperLink1 "  runat = " server "  NavigateUrl = ' <%# Doker.WebSite.AppCode.UrlLinks.GetMagazineDetailPreview(Eval("PublishType"),Eval("Code")) %> '  Target = " _blank " > 预览 </ asp:HyperLink >
             </ ItemTemplate >
         </ asp:TemplateField >
         < asp:TemplateField ShowHeader = " False " >
             < ItemStyle HorizontalAlign = " Center "  Width = " 40px "   />
             < ItemTemplate >
                 < asp:LinkButton ID = " LinkButton1 "  runat = " server "  CausesValidation = " False "  CommandName = " Generate "
                    OnClick = " LinkButton1_Click "  Text = " 生成 "  CommandArgument = ' <%# Eval("Code") %> ' ></ asp:LinkButton >
             </ ItemTemplate >
         </ asp:TemplateField >
         < asp:TemplateField ShowHeader = " False " >
             < ItemStyle HorizontalAlign = " Center "  Width = " 40px "   />
             < ItemTemplate >
                 < asp:LinkButton ID = " LinkButton2 "  runat = " server "  CausesValidation = " False "  CommandName = " Publish "
                    OnClick = " LinkButton2_Click "  Text = " 发布 "  CommandArgument = ' <%# Eval("Code") %> ' ></ asp:LinkButton >
             </ ItemTemplate >
         </ asp:TemplateField >
     </ Columns >
     < RowStyle BackColor = " #F7F6F3 "  ForeColor = " #333333 "   />
     < EditRowStyle BackColor = " #999999 "   />
     < SelectedRowStyle BackColor = " #E2DED6 "  Font - Bold = " True "  ForeColor = " #333333 "   />
     < PagerStyle BackColor = " #284775 "  ForeColor = " White "  HorizontalAlign = " Left "   />
     < HeaderStyle BackColor = " #5D7B9D "  Font - Bold = " True "  ForeColor = " White "   />
     < AlternatingRowStyle BackColor = " White "  ForeColor = " #284775 "   />
</ asp:GridView >

      从代码可以看出LinkButton是通过CommandArgument='<%# Eval("Code") %>属性把字段"Code"传给事件。
      在事件中又始何获取CommandArgument的值呢？如下代码：

string  _code  =  ((LinkButton)sender).CommandArgument;

      这边有一个小小的技巧是：点击LinkButton那一行的数据存储在GridViewRow中，然后再能过GridViewRow获取字段值，（注意sender就是LinkButton）代码如下：
      

         protected   void  LinkButton1_Click( object  sender, EventArgs e)
         {
            LinkButton btn = sender as LinkButton;
            GridViewRow row = btn.Parent.Parent as GridViewRow;

            SeedMaker sm = new SeedMaker();

            string publishType = string.Empty;
            string magName = string.Empty;
            string magBtype = string.Empty;
            string magStype = string.Empty;
            string magCode = string.Empty;
            string magVol = string.Empty;
            string volCode = string.Empty;
            string magCate = string.Empty;
            string content = string.Empty;
            string author = string.Empty;

            publishType = row.Cells[0].Text;
            magCode = row.Cells[1].Text;
            magName = row.Cells[2].Text;
            magVol = row.Cells[3].Text;
            volCode = row.Cells[4].Text;
            magCate = row.Cells[6].Text;
            author = row.Cells[7].Text;
            content = row.Cells[8].Text;
}
