This page allows a limit of 200 controls, and that limit has been exceeded in SharePoint

I was working on custom New form which I had created in Visual Studio 2012 as aspx page and attched it to the list.
I had large number of controls in the page and found this error when i tried to browse it through browser.

The solution for this error was to change a setting in web.config.

Here I am working on SharePoint 2013

So I went to

C:\inetpub\wwwroot\wss\VirtualDirectories\

Now open webapplication Eg:80 where your site is hosted

open web.config

Find the tag below in the web.config

 <SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="250" AllowPageLevelTrace="false">  


by default  MaxControls="200" is set to 200.So you get the exception.

You can change this according to your requirement.

This is resolve the issue.
