I love Master Pages
The past several days, I've been preparing my company's websites and connecting applications for our upcomming name change. I've never realized how much of a pain it is to change sites layout, colors, etc. until I had to modify a .NET application of ours we released a few months ago. I had to manually touch, at least, 50 various .ASPX and .ASCX files to get the new look and feel to propogate throughout the entire application. Talk about a pain in the butt.
So, I decided to create the new website using Metabuilders Master Pages control (site seems to be down, btw). Let me tell you, one application I moved over (that I put together about 2 weeks ago using MP) was easily migrated to the new look and feel within an hour, rather than several days. Master Pages is definately one of the biggest things I'm looking forward to having in ASP.NET 2.0, as it will make websites easier to manage when these sort of things come up.
Thanks for a great free control Andy!
