WPF Grid vs Stackpanel

Question

For WPF/Silverlight layout, is it better to use a Grid with lots of rows and columns, or tons of Stackpanels?

Answer 1

Both have strength (Grid/Stackpanel). Problem with Grid is the lines restructuring. The problem with Stackpanel is that no table structure (fixed columns width). So I think that is a good solution about this problems :-)

Definition styles

And using styles into Stackpanel
