我在Visual Web Developer 2010 Express中使用以下ASP.NET 2.0代码,每次关于我的控件时都会出现以下错误。
我想知道我是否可以在ASP.NET 4.0中使用特定的ASP.NET 2.0代码以及我做错了什么?
ERRORS:
Error 1 'lblTime_Init' is not a member of 'ASP.default_aspx'.
Error 2 'chkUnderLine_CheckedChanged' is not a member of 'ASP.default_aspx'.
Error 3 'chkStrikeout_CheckedChanged' is not a member of 'ASP.default_aspx'.
Error 4 'chkOverLine_CheckedChanged' is not a member of 'ASP.default_aspx'.
