[Enhancement] Grid : ActualWidth for ColumnDefinition And ActualHeight properties for RowDefinition

Description

It could be nice to have public getter of the Actual Width and Actual Height for a specific cell inside the Grid. First for now it’s not possible to know the Width and the Height of a specific Cell when GridUnitType is in Auto or Star Unit. We need to populate the cell with an empty filled View and get his Height and Width property.

By combining this with the spacing property, we will be able to know the X and Y position of unpopulated Cell inside a Grid.

Public API Changes

Actual Api :

//ColumnDefinition Class
internal double ActualWidth { get; set; }

//RowDefinition Class
internal double ActualHeight { get; set; }

Changed needed :

//ColumnDefinition Class
public double ActualWidth { get; internal set; }

//RowDefinition Class
public double ActualHeight { get; internal set; }

Intended Use-Case

It will help to locate an empty cell inside a Grid. Then beautiful and specific animation could be done with these properties.

Yeah sure, I mean animating it.

For what it’s worth, I would really appreciate having these exposed in order to be able to bind the width of columns in a grid in the header of a collectionview to the width of columns in that collectionview itself, among other things
