                Table td=new Table();
                td.ID = "td";
         
                TableRow tr;
                TableCell tc;
                TableCell tc2;
                TableCell tc3;
                int counter = GridView1.Rows.Count;
                for (int i = 0; i < counter; i++)
                {
                    CheckBox cb = ((CheckBox)(GridView1.Rows[i].Cells[0].FindControl("CheckBox1")));
                    Label lb1 = ((Label)(GridView1.Rows[i].Cells[1].FindControl("label1")));
                    Label lb2 = ((Label)(GridView1.Rows[i].Cells[2].FindControl("label2")));
                    Label lb3 = ((Label)(GridView1.Rows[i].Cells[3].FindControl("label3")));
                    Label lb4 = ((Label)(GridView1.Rows[i].Cells[4].FindControl("label4")));
                    
                    if (cb.Checked == true)
                    {
                       tr=new TableRow();
                        //Panel1.control
                     tc=new TableCell();
                        Label lb = null;
                        lb = new Label();
                        lb.ID = "lb" + i.ToString();
                        lb.Text = lb1.Text;
                        tc.Controls.Add(lb);
                        tr.Controls.Add(tc);
                        tc2 = new TableCell();
                       // this.Panel1.Controls.Add(lb);
                       // Panel1.Controls.Add(new LiteralControl("    "));
                        string sdf = (lb2.Text +" "+ lb3.Text +" "+ lb4.Text).ToString();
                        Label lb5 = null;
                        lb5 = new Label();
                        lb5.ID = "lb" + i.ToString();
                        lb5.Text = sdf;
                        tc2.Controls.Add(lb5);
                        tr.Controls.Add(tc2);
                       // this.Panel1.Controls.Add(lb5);
                        //Panel1.Controls.Add(new LiteralControl("    "));
                       TextBox tb = null;
                            tb = new TextBox();
                            tb.ID = "txt" + i.ToString();
                            tc3 = new TableCell();
                            tc3.Controls.Add(tb);
                            tr.Controls.Add(tc3);
                            td.Rows.Add(tr);
                            //this.Panel1.Controls.Add(tb);
                    //        Panel1.Controls.Add(new LiteralControl("<br>"));
                      //      Panel1.Controls.Add(new LiteralControl("<br>"));  
                    }
                    else
                    {
                    }

                }
                Panel1.Controls.Add(td);
            }
            catch (Exception re)
            {
                Response.Write("<script language=''javascript''>alert(''" + re.Message + "'');</script>");
            }
            finally
            {
            }
</br></br></table>

并在面板中查找表是

and for find out table in panel is

if (Panel1.Controls.Count == 0)
            {

            }
            else
            {
                Table tf = (Table)this.Panel1.FindControl("td"); 
                int counter = tf.Rows.Count;
                for (int i = 0; i < counter; i++)
                {

                }

}

任何想法都要先感谢

any idea thanks in advance

推荐答案

据我说，id og控件必须与html标记名称不同.

只需尝试更改它，看看是否有帮助..

According to me, the id og controls must be different than the html tag names.

Just try changing it and see if it helps..

好吧，只需将表名从"td"更改为其他名称.....

其背后的原因是"td"可能是预定义名称，除了创建表时所使用的表数据"外，别无其他.

只需更改它，看看是否有帮助....

Well just change your table name from "td" to some other name .....

The reason behind is that might be "td" is pre-define name which is nothing but "Table Data" same what we have used while creating Table.

Just change it see if it helps ....
