推荐答案

要访问asp.net代码中的元素，必须有 runat = server为该元素设置。

在您的情况下，我建议您在一个范围内包含要更改其显示属性的HTML，并将runat服务器标记添加到它。所以你的HTML将是这样的：

To access an element in your asp.net code, you must have runat="server" set for that element.
In your case, I would suggest you wrap the HTML whose display property you want to change in a span and add runat server tag to it. So your HTML will be something like:

<td>
    <span id="spnUsercontrolHtml" runat="server">
        <!--your user control html... or whatever html/text here -->
    </span>
</td>

你可以在服务器端访问spnUsercontrolHtml，你可以将它的可见性或样式设置为false / none。

You can access spnUsercontrolHtml at server side and you can set it''s visibility or style to false/none.

spnUsercontrolHtml.Visible = false;
spnUsercontrolHtml.Style.Add(HtmlTextWriterStyle.Display, "none");

请参阅下面的语法如果控件是文本框

TextBox myTextBox = userControl.FindControl（YourTextBox）作为TextBox;

myTextBox.Visible = false;

Please see below syntax If control is textbox
TextBox myTextBox = userControl.FindControl("YourTextBox") as TextBox;
myTextBox.Visible=false;
