如何在数据网格 WPF 中进行数学运算和组合数据

Question

I have imported data from excel to data grid in wpf application and I am trying to do some math on the data and also combine some columns.Please advise as what would be the best way to handle this.

to solve this I was trying to create a C# class, but I do not know how to map or link my class objects to a column in data grid?

  class Person
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string City { get; set; }
        public int Salary { get; set; }
    }

how can I map or link my C# class objects to a column in Data grid?

is it the easy way or I need to put everything into SQL database and write queries, I am good with SQL. Any advise will be highly appreciated. I am trying to figure this out from a real long time.

Answer 1

You can always extend your Person class with extra properties that expose getter only with whatever combinations you want... Something like...

class Person
    {
        public int Id { get; set; }
        // added the = ""; just to prevent nulls 
        public string Name { get; set; } = "";
        public string City { get; set; } = "";
        public int Salary { get; set; }
        // Now you can show these columns directly in the grid -- just an example
        public decimal MonthlySalary { get { return Math.Round(Salary / 12.0, 2 ); } }
        public string NameAndCity { get { return Name.Trim() + ",  " + City.Trim(); } }
    }

I'd start by learning some basics regarding the DataGrid . This page should be helpful for what you're doing: https://www.wpf-tutorial.com/datagrid-control/custom-columns/

You would define whatever columns you want to show in the DataGrid between the <DataGrid.Columns> tags. Each column has a Binding property which you use to set which property of your class ( Person ) is linked to that column via data bining.

As for doing math, you can create readonly properties for Person . Inside the readonly properties you could do calculations based on other properties and then return the result. To display the result, you would bind the readonly property to a column on the DataGrid . Keep in mind that if you the data in your Person class to be editable at runtime and have the math results update, you'll need to have Person implement INotifyPropertyChanged .
