我试图复选框添加到动态网页

I am trying to add Checkboxes dynamically to webpage

            string[] words = masg.Split('~');
            int size = words.Length;
            CheckBox[] cbl = new CheckBox[size];
            for (int i = 0; i < words.Length; i++)
            {
                cbl[i] = new CheckBox();
                cbl[i].Text = words[i].ToString();
                this.Controls.Add(cbl[i]);  
               // Response.Write("\n" + words[i]);
            }

我收到错误

checkbox类型的控制ctl01'必须放在与RUNAT =服务器的表单标签内。

我应该如何进行？使aspx页面上的哪些变化？请帮助。

How should I proceed ? What changes to make on aspx page ? Please help.

推荐答案

您应该改变它在表单中添加，因为这个正在引用您的页面。和你所创建程序或用 =服务器添加页面上的任何服务器控件应放置在窗体标签内。

You should change it to add in form, because this is referencing your Page. and any server control which you are creating programmatic or by adding on page with runat="server" should place inside a form tag.

像

this.Form.Controls.Add(cbl[i]);

或在窗体上放置一个占位符或面板。比你可以在其中添加

or place a placeholder or panel on the form. and than you can add in it

像

placeholder1.Controls.Add(cbl[i]); 

如果您的.aspx不包含表单标签，那么你应该放置一个表单标签有

If your .aspx does not contain a form tag, then you should place a form tag there

像

<form runat="server" id="form1">

 //Other mark up or server controls.

</form>
