使用asp.net中的Web控件动态添加复选框控件

Question

在我的Web应用程序中，我需要在asp.net中使用WebCotrols添加Textbox，Checkbox，Radio按钮等控件。我正在使用案例陈述。 所以任何人都可以告诉我如何做到这一点？

      WebControl ObjectToAdd;
        switch (obj)
        {
            case ObjectType.Text:
                ObjectToAdd = new TextBox();
                break;
            case ObjectType.Time:
                ObjectToAdd = new Calendar();
                break;
            case ObjectType.SingleSelect:
                ObjectToAdd = new RadioButton();
                break;
            case ObjectType.Number:
                ObjectToAdd = new TextBox();
                break;
            case ObjectType.MultiSelect:
                ObjectToAdd = new CheckBox();
                break;
            case ObjectType.Date:
                ObjectToAdd = new Calendar();
                break;
            default:
                ObjectToAdd = new TextBox();
                break;
        }

        var ChildItemResult = from myRow in dt.AsEnumerable()
                              where Convert.ToInt32(myRow["RelationParentID"]) == Convert.ToInt32(ViewState["ItemID"])
                              select myRow;

        foreach (var row in ChildItemResult)
        {


            ObjectToAdd.Attributes.Add ("value" , row["Caption"].ToString());

            phContianer.Controls.Add(ObjectToAdd);
        }
