A colon cannot be used in the ID of a .NET control. I quote from the following website: http://msdn.microsoft.com/en-us/library/system.web.ui.control.id.aspx
.NET 控件的 ID 中不能使用冒号。我引自以下网站：http: //msdn.microsoft.com/en-us/library/system.web.ui.control.id.aspx
"Only combinations of alphanumeric characters and the underscore character ( _ ) are valid values for this property. Including spaces or other invalid characters will cause an ASP.NET page parser error."
“只有字母数字字符和下划线字符 (_) 的组合才是此属性的有效值。包含空格或其他无效字符将导致 ASP.NET 页面解析器错误。”
Is there a reason why alphanumeric characters have to be used?
是否有理由必须使用字母数字字符？

As for why, I cannot give an answer, other than it makes sense to me as a developer that you never use anything other than alphanumerics and underscores for variable names. There's no obvious reason why that should not extend to control IDs as well.
至于为什么，我无法给出答案，除了对我作为开发人员来说，除了字母数字和下划线之外，您永远不会使用任何变量名作为变量名是有意义的。没有明显的理由不应该扩展到控件 ID。
