错误msg =在当前上下文中不存在 [英] error msg =does not exist in the current context

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="insert"  runat="server" Visible="False" ">

起初==> div可见是假

按下按钮后会显示

divinsert.visible = true;



然后在div

i有一个按钮用这个代码关闭div

divinsert.visible = false;





但我收到了错误信息msg =

1当前上下文中不存在divinsert这个名称





如何添加附加我的项目





=========

i corect它但是

这个错误w如图所示：



System.Web.UI.HtmlControls.HtmlGenericControl'不包含'visible'的定义，也没有扩展方法'visible'接受第一个参数可以找到类型'System.Web.UI.HtmlControls.HtmlGenericControl'（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;


but i recived erroe msg=
1 The name 'divinsert' does not exist in the current context


how can i add attach my proj


=========
i corect it but
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

嗯...... ID是插入，而不是divinsert



所以我建议更改按钮代码中的名称？

Um... The ID is "insert", not "divinsert"

So I would suggest changing the name in your button code?
