Hi friends.
Can we change ColumnDefinitions via a StoryBoard in WPF?
e.g : I wanna change the following ColumnDefinitions

<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Height="0*"/>
</Grid.ColumnDefinitions>

to this one :

<Grid.ColumnDefinitions>
<ColumnDefinition Height="0.585*"/>
<ColumnDefinition Height="0.415*"/>
</Grid.ColumnDefinitions>

Thanks in advance.

Yep, you can do that, but there is some tricky stuff involved. You have to create a custom animation for the GridLength data type. Lucky for you, that trickery has already been done by somebody. Look at the WPF Tutorial - Part 2 : Writing a custom animation class article, which does exactly what you want.
