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。

  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)
  {

  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

C# code

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())));   }}

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");
 }
