您要为此错误的页面必须在其页面属性中为其自身定义了母版页:MasterPageFile="~/MasterPage.master"
完成后，aspx应该具有一个内容"页面，以便母版页可以在渲染时使用它.您的页面设计此处没有任何内容面板.

两种选择:
1.删​​除母版页的页面属性. =>删除MasterPageFile="~/MasterPage.master"或
2.在"Declaration_Form.aspx"中添加内容"控件.在该内容中添加页面设计. (如果需要，您可以参考内容页面的设计以查看其他页面.)

在这里阅读有关它们的所有信息: MSDN:ASP.NET母版页 [

The page for which you are getting this error must have defined a master page for itself in it''s Page attributes: MasterPageFile="~/MasterPage.master"
Once you do it, your aspx should have a Content page such that master page can use it while rendering. Your page design here does not have any content panel in it.

Two options:
1. Remove page attribute for master page. => remove MasterPageFile="~/MasterPage.master" OR
2. Add Content control in your Declaration_Form.aspx. Add you page design in that content. (If needed, you can refer the design of content page looking at other pages.)
