It seems that you have an error in your .aspx file which is triggered when you launch this.DataBind() in your PageLoad() . 似乎您的.aspx文件中有错误，当您在PageLoad()启动this.DataBind()时触发了该错误。

I think that you are trying to get the parameter value from am object which is null, something like <%# YourObject.value %> and YourObject is null. 我认为您正在尝试从为null的am对象获取参数value ，例如<%# YourObject.value %>并且YourObject为null。 After that you get ArgumentNullException . 之后，您将获得ArgumentNullException 。
