'visible'的定义，没有扩展方法

问题描述

我有一个div，它将runat =server添加到它

i have a div that add runat="server" to it

<div id="divinsert"   runat="server" Visible="False" ">

起初==> div可见假

按下按钮后会显示

divinsert.visible = true;



然后在div

i有一个用这个代码关闭div的按钮

divinsert.visible = false;



如何添加附加我的proj

=============================



出现此错误：



System.Web.UI.HtmlControls.HtmlGenericControl'不包含'visible'的定义，也没有扩展方法'visible'接受第一个可以找到类型'System.Web.UI.HtmlControls.HtmlGenericControl'的参数（你是否缺少using指令或程序集引用？）

at first ==>div Visible is "False"
after press a button it will be show
divinsert.visible = true;

then on div
i has a button to close div with this code
divinsert.visible = false;

how can i add attach my proj
=============================

this error was appear:

System.Web.UI.HtmlControls.HtmlGenericControl' does not contain a definition for 'visible' and no extension method 'visible' accepting a first argument of type 'System.Web.UI.HtmlControls.HtmlGenericControl' could be found (are you missing a using directive or an assembly reference?)

推荐答案

divinsert.Visible = true;
