A colleague of mine is trying (for the first time) to develop an application with SharePoint Designer. The structure of the data is very simplistic -- however there are a lot of fields/columns (several hundred). He's complaining that the designer is incredibly slow. Any change apparently causes some type of screen refresh that takes an intolerable amount of time. Unfortunately, I know precious little about SharePoint development (I'm an Asp.Net dev).
Are there alternatives to SharePoint developer for this type of work? Is it feasible to bypass the WYSIWYG view and edit the code directly? I'm curious to hear what others have done to deal with this issue.
