How can I set the MaxWidth of a WrapPanel to be equal to the width of the grid it's in?

Question

WPF

The form has a grid that contains a WrapPanel. The initial grid width is automatic. You need to make the maximum width of the WrapPanel the same as the grid, so that when the form is stretched and contracted, the elements on the wrapPanel are transferred or returned to the next / previous line. How to do it? Is it possible only in xaml? If not, how can it be done through binding using the MVVM pattern?
