wpf mouse hover grid row first element - wpf

Question

Is it possible to make when i hover over grid (template for items control) to change font color for first and last column in a row (this specific row which i am hovering)
What i want is "RowNumbering" object to change font color when we hover his "parent" row. To sort of highlite that row text.
Imagine it as a table:
where o is just a seat, and numbers are row numbers, when i hover over "o" i would like to change row number font color. I hope it's clear what i try, i did strip xaml to a minimum. Also would love to have this done over xaml if possible instead over code. Example bellow when i hover over "o" in second row.
1 | o | o | o | o | 1
2 | o | o | o | o | 2
3 | o | o | o | o | 3

I think you're using the wrong control type. WPF layout controls like Grid etc are useful when you want WPF to handle the layout of controls for you. In your case, however, the layout is already implicit in your data structures by virtue of the RowEx/ColumnEx properties. What you're trying to do is shoe-horn complex layout requirements into a layout control that's not really designed for it. You've already run into problems with this before, which has necessitated the use of that GridHelper. It's probably not going to get any better.
I write airline check-in systems for a living and find myself implementing systems very similar to what you're doing all the time. Experience has taught me that in cases like this, you're usually better off using a Canvas. It does require you to add much of the functionality that existing controls give you for free (e.g. row-specific behavior, which is something DataSet is better at handling), but it will give you complete flexibility over your layout and behaviors, and will also be much easier to unit-test.
To answer your question though, you could create a new class called Row with a transparent background that spans all of your columns. Bind that control's MouseEnter/MouseLeave events to update a local property in Row, and in those properties setters have them set/clear a highlight flag in the two RowNumbering instances that appear in that row. Alternatively each instance of RowNumbering could contain a property that points to its corresponding Row instance, and you could set a DataTrigger to trigger on that instead.
