My asp page dispay the following error "Error Creating Control - contentObject reference not set to an instance of an object." in the design mode even if i run it with any problem in the server.

推荐答案

对象引用未设置为对象实例
当您尝试使用对象的属性为null时，会发生此错误.

Object Reference not set to an instance of an object
This error happens when you try to use a property of an object that is null.

听起来您的ASPX页面设计中包含一些"Control-contentObject"，但未正确使用.确保正确形成了控制标签，并且定义了所需的属性.莫名其妙地没有初始化.

It sounds like your ASPX page design is having some ''Control - contentObject'' that is not properly being used. Make sure the control tag is correctly formed and the properties needed are defined. Somehow it''s not initialized.
