I have a WEB project that consists of four web pages; each of them has one or two radGrid. On my local PC it works fine, but when I move it to the server, three of the web pages works, but the fourth doesn’t open the edit form when I click the edit button.
Then you found limit to have only three pages with Telerik grid working live :) To be serious, do you get any javascript errors on your site when this happen? I use Firebug to watch for them in FireFox.
Did code which opens the edit form gets executed? Any changes that you made before uploading the page live? Compare the local and server version to find the cause.
