怎么获取 <textarea id="question_text" class="input-text" rows="4" cols="110">
  <%# Eval("ReplyContent")%>
  </textarea>
的值

------解决方案--------------------------------------------------------
你需要写成
 <textarea id="question_text" runat=server class="input-text" rows="4" cols="110">
<%# Eval("ReplyContent")%>
</textarea>

然后后台
//得到指定行的
HtmlTextArea q = 
DataList1.Items[i].FindControl("question_text") as HtmlTextArea;


//得到全部的
protected void Button1_Click(object sender, EventArgs e)
{
foreach (DataListItem line in DataList1.Items)
{
HtmlTextArea q = line.FindControl("question_text") as HtmlTextArea;
Response.Write("<li>"+q.Value);
}
}
