public void AddDynamicControl()
       {
           int j=5;
       for(int i=1; i<=j; i++)
           {
               CheckBox objcheckbox = new CheckBox();
               objcheckbox.Name = i.ToString();
               objcheckbox.Text = i.ToString() + "checkbox";

           panel1.Controls.Add(objcheckbox);

but its adding only one control after execution of this program therefor i am adding 5 controls according to my for loop.......

have any answer.......???

推荐答案

对我来说它添加了5个控件。



检查下面稍微修改过的代码（而不是我已经输入ID的名字）：

For me its adding 5 controls.

Check the slightly modified code below(Instead of Name I have put ID):

protected void Button1_Click(object sender, EventArgs e)
        {
            int j = 5;
            for (int i = 1; i <= j; i++)
            {
                CheckBox objcheckbox = new CheckBox();
                objcheckbox.ID = i.ToString();
                objcheckbox.Text = i.ToString() + "checkbox";

                Panel1.Controls.Add(objcheckbox);
            }
        }

也许它只是一个视觉效果而且它们都是在同一个地方绘制的。尝试添加

Maybe it''s just a visual thing and they are drawn all in the same place. Try adding

objcheckbox.Location = new Point(0, 10 * i);

到你的循环。

这应该将复选框放在另一个之下。

to your loop.
That should place the checkboxes one below the other.

public void AddDynamicControl()
       {
           int j=5;
       for(int i=1; i<=j; i++)
           {
               CheckBox objcheckbox = new CheckBox("CheckBox"+i);
               objcheckbox.Name = i.ToString();
               objcheckbox.Text = i.ToString() + "checkbox";

           panel1.Controls.Add(objcheckbox);
           }
       }

只是这样做

just do like this
