GridView：在服务器上运行时数据库错误，在本地主机上运行正常

Question

I am working on a project where I must return the following columns in a gridview, and search can be narrowed down by 0-7 filters.

• AppID
• ClientName
• ProjectNo.
• ProjectSubNo.
• ProjectTitle
• AppType
• AppSubType
• NodeName
• Username

I am able to do this fine on my local machine, but it returns an error saying that it cannot find the ProjectTitle Field in the database source when I run it on the server. The rest of the code is fine, as there is no error displayed when I remove the ProjectTitle column from the GridView. The following is my code.

Any suggestions on what would be causing this?

Answer 1

Are you sure the remote database contains the field ProjectTitle ?

If you change the localhost connection string localhost so it uses the remote database (but still using the localhost project) do you still get the error? (This will determine whether the problem lies in the code, or in the database.)
