I am new for Ext js library. So kindly help me out. I have downloaded 'ext-2.1.zip' file and unzipped it. But when I open edit-grid.html in browser, I am not getting any data from xml file to editable grid. Here I have unzipped it in my folder and didn't put in any server. Is the problem because I didn't put this application in server? If yes, which server, which type of configuration is required? If no, may I know how can I get proper data in grid? also Please provide some good documents or tutorial link for EXT js library.
