Hi there,<BR><BR>I am currently developing an asp.net web application and was wondering if I put all my functions and procedures in one code behind file if this would be better then having multiple code behind files (as Visual Studio.net does)? Is there any performance problems if you have one big code behind file?<BR><BR>What is the best practise here?<BR><BR>thanks - matt<BR>If you are looking for the ultimate code reuse then you might want to consider putting your functions into a component. I don't think there is any real performance issue in have your functions in one .vb file, since it gets compiled and not parsed each time. <BR><BR>I personally think its better to have your components broken out into different components organized by their specific category. It makes it easier to debug and add to later. just my $.02.<BR><BR>
