错误时这么说的：当传递具有新行的 DataRow 集合时，更新要求有效的 InsertCommand。


using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls.WebParts;

public partial class Masters_AdminBlue_Demo_Add : System.Web.UI.Page
{
private int CateId;

protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["CateId"] != null)
{
CateId = Convert.ToInt32(Request.QueryString["CateId"].ToString());


}
}

protected void Button1_Click1(object sender, EventArgs e)
{
COOL.NEWSTableAdapters.CMS_ContentTableAdapter adp = new COOL.NEWSTableAdapters.CMS_ContentTableAdapter();

COOL.NEWS.CMS_ContentRow dr =dt.NewCMS_ContentRow();

dr.CateID = CateId;
dr.CMS_Cnt =Convert.ToString(FCKeditor1.Value);
dr.CMS_Title =Convert.ToString(tbOld.Text) ;


dt.AddCMS_ContentRow(dr);

if (adp.Update(dt) > 0)
{
Tool.Message.ClientMsgPrompt(this, "添加成功");
tbOld.Text = "";
FCKeditor1.Value = "";
}

else
Tool.Message.ClientMsgPrompt(this, "添加失败");
}

protected void Button2_Click(object sender, EventArgs e)
{
Response.Redirect(string.Format("Add.aspx?CateId={0}", CateId));
}
}

是什么问题呢？页面跳转，参数没有传递过去？还是？？？
如果是参数没有传递过去，这样

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

public partial class Masters_AdminBlue_Demo_Add : System.Web.UI.Page
{
  private int CateId;

 protected void Page_Load(object sender, EventArgs e)
{
     if(!IsPostBack)
     {
         if (Request.QueryString["CateId"] != null)
         {
               CateId = Convert.ToInt32(Request.QueryString["CateId"].ToString());
               ViewState["cateID"]  = Convert.ToInt32(Request.QueryString["CateId"].ToString());
         }
      }
  }

protected void Button1_Click1(object sender, EventArgs e)
{
  COOL.NEWSTableAdapters.CMS_ContentTableAdapter adp = new COOL.NEWSTableAdapters.CMS_ContentTableAdapter();
  COOL.NEWS.CMS_ContentDataTable dt = new COOL.NEWS.CMS_ContentDataTable();
  COOL.NEWS.CMS_ContentRow dr =dt.NewCMS_ContentRow();

  dr.CateID = int.Parse(ViewState["cateID"].ToString()); 
  dr.CMS_Cnt =Convert.ToString(FCKeditor1.Value);
  dr.CMS_Title =Convert.ToString(tbOld.Text) ;


  dt.AddCMS_ContentRow(dr);

  if (adp.Update(dt) > 0)
  {
       Tool.Message.ClientMsgPrompt(this, "添加成功");
       tbOld.Text = "";
       FCKeditor1.Value = "";
   }
  else
   {
      Tool.Message.ClientMsgPrompt(this, "添加失败");
    }
}

   protected void Button2_Click(object sender, EventArgs e)
   {
        Response.Redirect(string.Format("Add.aspx?CateId={0}",  int.Parse(ViewState["cateID"].ToString())));
   }
}

不用发给我，你自己要学会调试，你得知道是报什么错？之后是哪行报的错？

[wurenqudedengguang]

if (adp.Update(dt) > 0)这行的错误，但是我觉得前面有什么事错了的，跟这句是没关系的

当传递具有新行的 DataRow 集合时，更新要求有效的 InsertCommand。

说明

protected void Button1_Click1(object sender, EventArgs e)
{
COOL.NEWSTableAdapters.CMS_ContentTableAdapter adp = new COOL.NEWSTableAdapters.CMS_ContentTableAdapter();
COOL.NEWS.CMS_ContentDataTable dt = new COOL.NEWS.CMS_ContentDataTable();
COOL.NEWS.CMS_ContentRow dr =dt.NewCMS_ContentRow();

dr.CateID = CateId;
dr.CMS_Cnt =Convert.ToString(FCKeditor1.Value);
dr.CMS_Title =Convert.ToString(tbOld.Text) ;


dt.AddCMS_ContentRow(dr); //这个方法有问题

if (adp.Update(dt) > 0)
{
Tool.Message.ClientMsgPrompt(this, "添加成功");
tbOld.Text = "";
FCKeditor1.Value = "";
}

else
Tool.Message.ClientMsgPrompt(this, "添加失败");
}
