Animating Grid Column or Grid Row in XAML?

Question

Is there any way i can animate Grid column width or Grid row height from XAML?

Answer 1

The ColumnDefinition.Width and RowDefinition.Height properties are of type GridLength, and there is no built-in animations for this type. So if you want to do that, you will probably have to create your own GridLengthAnimation class. That's probably not too impossible if you take DoubleAnimation as an example, but not easy either...

EDIT: actually, there are several interesting results if you search "GridLength animation" on Google...
