binding observable collection of custom objects containing array

Question

i'm learning wpf and binding and all and i have a gridview and a custom object

i'm trying to bind a list of custom objects to the grid my custom object is designed like this

 Public class myObject 
  {
    protected int myInt {get; set;}
    protected ObservableCollection<string> myStrings{get;set;}
    protected double myDouble{get;set}

    public myObject(int aInt, string aString, double aDouble)
   {
    myStrings = new ObservableCollection<string>(); 
    string[] substrings = aString.split('/');
    this.myInt = aInt;


     foreach (string s in substrings)
     {
         myStrings.Add(s);
     }

     this.myDouble = aDouble;
    }

}

so i then create an observablecollection of these objects and bind them to the grid

the double, int are displaying just fine in the grid but the array is displaying the pointer, i have a column filled with

  "System.Collections.ObjectModel.ObservableCollection `1[System.String]" 

Could anyone help me displaying the content of the observableCollection in the grid like, each item of the collection would get a column.

Thanks by advance !

SOLUTION I FOUND

I tried using templates, but it didn't please me so i used ExpandoObjects I first created a list of dictionaries containing each row of my future grid, then turned them into expando objects using https://theburningmonk.com/2011/05/idictionarystring-object-to-expandoobject-extension-method/ Big thanks to him for his awesome custom method

then i just bound the observable collection of ExpandoObjects to my radgridview and TADA i now have my dynamic grid with dynamic objects

Thanks again for your answers i learnt some usefull informations on templates !

What looks more appropriate in you case is to use RowDetailsTemplate to define a child DataGrid/GridView to display the Strings collection, displaying the strings collection at the same level as the other properties could be a hard task to do (and doesn't make much sense). Here a sample of how to define a DataGrid within another one (same thing using GridView/ListView, DataGrid looks more appropriate).

 <DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <DataGridTextColumn Header="MyInt" Binding="{Binding  MyInt}"/>
            <DataGridTextColumn Header="MyDouble" Binding="{Binding  MyDouble}"/>
        </DataGrid.Columns>
        <DataGrid.RowDetailsTemplate>
            <DataTemplate>
               <ListView ItemsSource="{Binding MyStrings}"/>
            </DataTemplate>
        </DataGrid.RowDetailsTemplate>
    </DataGrid>

MyObject

public class MyObject
{
    public int MyInt { get; set; }
    public ObservableCollection<string> MyStrings { get; set; }
    public double MyDouble { get; set; }

    public MyObject(int aInt, string aString, double aDouble)
    {
        MyStrings = new ObservableCollection<string>();
        string[] substrings = aString.Split('/');
        this.MyInt = aInt;


        foreach (string s in substrings)
        {
            MyStrings.Add(s);
        }

        this.MyDouble = aDouble;
    }

}
