带复选框的 WPF 数据网格过滤器

Question

I have a datagrid in WPF with the columns first name, last name, hours, and grade. I want to filter it with checkboxes to only show the something like people with >200 hours, or only people in 9th grade. I want it to be dynamic so you can check and uncheck the checkbox and the datagrid would dynamically filter for all the checked ones. For example, only those in 9th and 10th grade with <100 hours would be 3 checkboxes, the 9th grade, 10th grade, and the <100 hours filter all applied to the Datagrid. Can someone help, I haven't been able to find what i'm looking for.

 class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public int ID { get; set; }
        public int Grade { get; set; }
        public double Hours { get; set; }
    }

List<Person> people = new List<Person>()

Then in wpf, I have a simple datagrid where I make the TestDatagrid.itemsource= people and I want to filter the datagrid programmatically with a set of checkboxes.

Answer 1

What about LINQ? like Checkbox.IsChecked TestDatagrid.itemsource = people.Where(p => p.Grade > 100).Select(p =>p); May be the syntax is wrong - I have not installed VisualStudio on this computer.
