WPF中DataGrid中逗号分隔的列值

Question

I am using DataGrid in WPF. I am binding list of Teacher class to the DataGrid .

class Teacher
{
   public string Name{get;set;}
   public int Age{get;set;}
   public List<Subject> Subjects {get;set;}
}

class Subject
{
   public string Name{get;set;}
   public int Weight {get;set;}
}

I have setup the DataGrid for columns "Teacher Name", "Age", "Subjects". I wan the third column "Subjects" to have comma-separated list of Subject class' Name property belonging to Subjects property of Teacher class.

How to do it ?

Answer 1

Add a property to the class that returns the subject comma seperated using string.Join. Bind the property to the grid.

Check below for using string.Join:

List<string> val = new List<string>();
val.Add("A");
val.Add("B");
val.Add("C");

string res = string.Join(", ", from item in val select item); 

Hope it helps.

Answer 2

If the Teacher obj is t1.

Try to assign values to grid like:

t1.Name
t1.Age
string.Join(", ", from s in t1.Subjects select s.Name)

This way no need to add property for subject. Try to do like this.

Hope it helps.
