推荐答案

我们可以从code后面使用占位符控件添加动态控件一样文本框，单选按钮列表，复选框列表insde Repeater控件。

We can add dynamic controls like Textbox, Radiobuttonlist, Checkbox List insde repeater control from code behind using placeholder control.

动态控制Asp.Net使用占位符（C＃）？

protected void rptPrint_ItemDataBound(object sender, RepeaterItemEventArgs e)
{

  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)         
  {

    string options = (HiddenField)e.Item.FindControl("hfAnswer")).Value;

    string type = ((HiddenField)e.Item.FindControl("hfType")).Value;
    Label lblquestion = ((Label)e.Item.FindControl("LblQuestion"));
    PlaceHolder phRow = (PlaceHolder)e.Item.FindControl("phRow");

    if (type == "Text")
    {
      TextBox txtAnswer = new TextBox();
      phRow.Controls.Add(txtAnswer);
    }


    else if (type == "Check")
    {
      CheckBoxList chklist = new CheckBoxList();
      chklist.RepeatDirection = RepeatDirection.Horizontal;
      chklist.Font.Italic = true;

      chklist.RepeatColumns = 4;

      foreach (string option in options.Split(','))
      {

        ListItem items = new ListItem();
        items.Text = option;
        items.Value = option; 
        chklist.Items.Add(items);
      }                   
      phRow.Controls.Add(chklist);
    }

    else
    {
      RadioButtonList rdblist = new RadioButtonList();
      rdblist.RepeatDirection = RepeatDirection.Horizontal;
      rdblist.Font.Italic = true;

      rdblist.RepeatColumns = 4;

      foreach (string option in options.Split(','))
      {

        ListItem items = new ListItem();
        items.Text = option;
        items.Value = option; 
        rdblist.Items.Add(items);
      }                   

      phRow.Controls.Add(rdblist);
    }

  }

}
