RadGrid multiple records from a form

[hamda]

hi,
I have a regular form with textboxes and dropdowns when I fill this form then press a button it should add this info to a grid of one record that I just entered from the form. The problem is I want to add multiple records to this grid, but when i fill again then insert it to the grid it replaces the old record I inserted earlier. I use a Select Function that takes the id of the record inserted then rebind it to the RadGrid.

How can I add multiple records to a grid from a form??
This is the grid needDataSource function:

protected void grdInsertPerson_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            List<Person> per = null;
            List<Person> perResult = new List<Person>();
            //per = Person.SelectCmd(-1, "", -1, -1, "", "", -1,"", 1);
            try
            {
                //per = Person.SelectCmd(-1, "", -1, -1, "", "", -1, Session["PersonId"].ToString(), 1,-1);//count1
                per = Person.SelectCmd(-1, "", -1, -1, "", "", -1, "", 1, -1);//count1

                if (per.Count > 0)
                {
                  for (int i = 0; i < per.Count; i++)
                    {
                        if (per[i].PersonId == Session["PersonId"].ToString()) //the session store the id of the person inserted in the form

                        {
                            perResult.Add(per[i]);
                        }
                    }
                    grdInsertPerson.Visible = true;
                    grdInsertPerson.DataSource = perResult;

                }

            }
            catch (Exception exp)
            {
                Page.Validators.Add(new CheckPoints.StaticValidator("Can't show data"));
            }


        }

Hello hamda,

RadGrid is a data-bound control. You need to first insert the record into the data-source to which you have bound the grid and then rebind it.

Hope it helps.
