C# 如何在内容占位符中循环控件

如何在内容占位符中为每个使用

查找控件。我将代码放在
Div标记中
但我不明白

有人能帮我吗

protected void btnbatch_Click(object sender, EventArgs e)
{       
    Button btnactual= sender as Button;
    ContentPlaceHolder myContent =
(ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1");
}

试试这个

Protected void btnbatch_Click(object sender, EventArgs e)
{

    Button btnactual= sender as Button;
    ContentPlaceHolder myContent = 
   (ContentPlaceHolder)this.Master.FindControl("ContentPlaceHolder1");

    foreach (Control ctrl in myContent.FindControl("divBatches").Controls)
    {
        if (ctrl.ID == btnactual.ID)
        {
           //blah blah
        }
     }
  }
