Add nameattribute to the Dynamic control :
name向动态控件添加属性：
<textarea id="txtImagename1" name="txtImagename1" runat="server" rows="1" cols="50">
</textarea>
from your codebehind :
从你的代码隐藏：
Request.Form["txtImagename1"]
回答by Htin Aung
TextBox txtImageName = (TextBox)Page.FindControl("txtImagename1");
string strFromTextArea = txtImageName.Text;
Note :
笔记 ：
- "Page" should be container of your textarea control. If your textarea is in panel, use your panel object instead of Page.
- Multiple lines textbox control is textarea in HTML control.
- “页面”应该是你的 textarea 控件的容器。如果您的 textarea 在面板中，请使用您的面板对象而不是页面。
- 多行文本框控件是 HTML 控件中的文本区域。
