在table中用findcontrol找textbox控件？？？？

Question

试试在页面上放两个TextBox,ID分别为txt1,txt2

Answer 1

txt1 is a variable, to use FindControl, you need to assign the ID property, for example
System.Web.UI.WebControls.TextBox txt1=new System.Web.UI.WebControls.TextBox();
txt1.Text="chenwd";
                           txt1.ID = "txt1"; qxcells.Controls.Add(txt1);
qxrows.Cells.Add(qxcells);
this.Table1.Rows.Add(qxrows); System.Web.UI.WebControls.TextBox txt2;
txt2=(System.Web.UI.WebControls.TextBox )Table1.FindControl("txt1");
this.Label1.Text=txt2.ID;

Answer 2

table 不是服务端控件，你在客户端在TABLE那边加上 runat=server就可以了
