超级简单的问题。
foreach (DataListItem dl in this.DataList1.Items)
        {         
           string date = ((TextBox)dl.FindControl("TextBox1")).ID;
                           
       }

Answer 6

谢谢慕白兄的回复，我现在想实现的功能是查出页面上所有的控件，对于页面上其他控件，比如：TextBox,Label等都已获得，就是对于datagrid中模版列中的控件不知如何得到，我现在将我的后台部分代码粘上开，麻烦帮我看看应该如何写？
 public void InitSystemTranslation(System.Web.UI.Page obj)
        {
            HtmlForm form = new HtmlForm();
            
            for (int i = 0; i < obj.Controls.Count; i++)
            {
                if (obj.Controls[i] is HtmlForm)
                {
                    form = obj.Controls[i] as HtmlForm;
                }
            }
        foreach (object obj1 in form.Controls)
            {
                if (obj1 is Panel)
                {
                    foreach (object obj2 in (obj1 as Panel).Controls)
                    {
                        if (obj2 is Button)
                        {
                            Button Btn = obj2 as Button;
                        }
                        else if (obj2 is DataGrid)
                        {
                            DataGrid Dtg = obj2 as DataGrid;                            if (Dtg.ID.Length > 4 && Dtg.ID.Substring(Dtg.ID.Length - 4) == "Head")
                            {
                                //如何写？
                            }
                        }
                        else if (obj2 is Label)
                        {
                            Label Lbl = obj2 as Label;                        }
                    }
                }
            }
        }
