ASP.NET controls appearing twice on master page

[Jaminxz]

I'm new here so hello guys! hope you can help me.

I'm building a web-application for a college project and running into difficulties with controls. I'm trying to filter a gridview with a drop down list, but when i use the configure data source wizard every control on the page appears twice and not matter which i select my gridview doesn't build(i think the page might be getting 'confused' as to which one i'm using). I've definitely followed the tutorial right, rebuilt the page a million times and found that it even happens on new pages that are attached to master pages. It doesnt happen on new pages not in the master so i'm thinking possibly its something to do with my master page? does anybody have any ideas where i could start looking, or is this a bug in Visual Studio?

the more "code" you write use IDE wizards the less you can debug what's happening. I would recommend abandoning these in favor of actually writing code.

1. you are in control of what's happening
2. you can debug the code
3. you can test the code

check your master page to make sure you only have 1 tag for ContentPlaceHolder if you have 2 this could be why.
If not, delete the master page and re-create.
