请高手帮忙
需求，部分代码已经写好，还差 删除、添加和取里面的值的功能，
先贴一张图吧 cs 代码// 从数据库里面 填充到ds table里去。
public DataTable date_sa(string ReworkFormNo)
{
SqlConnection conn = dbbase.DB.createconn();
string sql = "select Parts_Name,Part_No,Price from[ReworkForm_Parts] where ReworkFormNo='" + ReworkFormNo + "'";
SqlDataAdapter sda = new SqlDataAdapter(sql,conn);
DataSet ds = new DataSet();
sda.Fill(ds);
return ds.Tables[0]; }//加载的时候 在文本框里面显示的数据、
protected void Button1_Click(object sender, EventArgs e)
{
int i;
int j;
DataTable dt = date_sa("RW091013014");
int rowcounts = dt.Rows.Count;
int cellcounts = dt.Columns.Count;
for (i = 0; i < rowcounts; i++)
{
TableRow tr = new TableRow();
Table1.Rows.Add(tr);
for (j = 0; j < cellcounts; j++)
{
TableCell td = new TableCell();
TextBox tb = new TextBox();
if (j % 4 == 0)
{
Button bt = new Button();
bt.ID = "bt" + i + j;
bt.Text = "删除";
td.Controls.Add(bt);
}
tb.ID = "tb" + i + j;
tb.Text = dt.Rows[i][j].ToString();
td.Controls.Add(tb);
tr.Cells.Add(td); } } }谢谢 大家 帮帮忙

TextBox textbox1=new TextBox();
div.controls.add(textbox1);
this.div.Controls.Add(new LiteralControl(" </td> </tr> </table>" + "\n"));
试一下

思路，用gridview去绑定带空行的datatable
{
for (int i = 0; i <3; i++)
{
//创建控件并添加到panel中
Button bt = new Button();
bt.ID = i.ToString();
bt.Text = "删除"; TextBox tb11 = new TextBox();
tb11.ID ="tb"+i.ToString() + "1";
tb11.Text = i.ToString();
TextBox tb12 = new TextBox();
tb12.ID = "tb" + i.ToString() + "2";
tb12.Text = i.ToString();
TextBox tb13 = new TextBox();
tb13.ID = "tb" + i.ToString() + "3";
tb13.Text = i.ToString(); this.Panel2.Controls.Add(bt);
this.Panel2.Controls.Add(tb11);
this.Panel2.Controls.Add(tb12);
this.Panel2.Controls.Add(tb13);
//为按钮注册事件
bt.Click += new EventHandler(bt_Click);
}
} void bt_Click(object sender, EventArgs e)
{
Button bt = (Button)sender;
string id = bt.ID;
TextBox tb11 = (TextBox)this.Panel2.FindControl("tb" + id.ToString() + "1");
Response.Write("tb11的text属性为"+tb11.Text);
}
看下这段代码看是否有启发。。这段代码完成注册控件，为控件添加事件。读取需要的textbox的值的功能。
//var tb=document.getElementById("T_model");//这里不能用jq的选择器，
var tb=$("#T_model").get(0);//$("#T_model")[0]//将jquery对象转化为dom对象才能使用下面的方法
var tr=tb.insertRow(tb.rows.length);//添加行
var lasttd=tr.insertCell(tr.cells.length);//插入删除那个单元格,现在要想放下面就把这两行移到for后面就行了
lasttd.innerHTML="<input type='button' onclick='btndel(this)' value='Delete'/>";
var start=tr.cells.length,end=start+3;
for(var i=start;i<end;i++) {
var td=tr.insertCell(i);//添加单元格
td.innerHTML="<input type='text'/>";//往单元格里插入html或者$(td).html("<input type='text'/>");
}
}
