Improve the way RadPageLayOut reacts to different view port sizes and make it consistent with the DeviceScreenSize detected with the Device Detection framework
Rows and columns should have the same features - like in WPF. Why not add Span and ColSpan to rows. It's a given that a row should default to 100% width of containing element. RowSpan could set the width to that defined by the grid system - ie: Span 6 (of 12) is 50% width. The span could also be a hard-coded px value. Similar to using spans instead of divs in HTML. ColSpan could interrogate the columns within the row and adopt their widths - ie: ColSpan 2 = same width as the 1st and 2nd columns combined.
As of now, the gutter (space between the columns) is hardcoded to 15 pixels. Perhaps we could have a server side property, say Gutters, that accepts an integer value and results in a generated class, say t-gutter-10. We can also have predefined styles, say 10, 20, 15 etc so the base variants are covered. If a developer wants, say 56 pixels gutter, it can be either set directly overwriting the styles or scoping trough the generated class t-gutter-56.
