问题:GridVeiw 删除记录出错:至一个参数没有被指定.
GridView可以执行更新操作.
如果在ads_wod的SelectQuery中只使用表WOD的字段,可以正常删除记录和更新记录,
但是加入表Material中的字段的后,就只能更新记录,不能删除记录.test1.apsx.cs代码:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.OleDb;
public partial class test1 : System.Web.UI.Page
{
protected int CurrentPage;
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
}
}
protected void ImageButton2_Click1(object sender, ImageClickEventArgs e)
{
if (tb_wono.Text != string.Empty)
{
Session["woid"] = tb_wono.Text;
}
}
}
