Then I tried to give it a value in the ABC,aspx.cs, the code is

推荐答案

为了使aspx文件中的任何项目都对后面的代码可见，您必须使用runat ="server"对其进行标记并重新编译.这应该是您需要做的所有事情.

In order for any item in your aspx file to be visible to the code behind you have to tag it with runat="server" and recompile. It should be all you need to do.

您好
如果您像下面这样写，则仅在客户端浏览器上可用，这意味着您可以使用客户端脚本(javascript/jQuery)调用此控件，但不能在C#.cs文件中调用



但是，如果要从C#.cs文件访问控件，则必须使用runat属性.如果您运行atat ="SERVER"




谢谢

Hi
if you write like below it only availabe on client browser means u can call this control by using client script(javascript/jQuery) but not in C# .cs file



but if you want to access the control from C# .cs file u have to use runat attribute . if you runat="SERVER"
