Dynamic binding of a DataGridTemplateColumn with a ComboBox inside

Question

Hi all and thank you in advance.
I wish you could help me 'cause I'm quite a newbye in this world (C# and WPF).
I need to bind a ComboBox field inside a DataGrid with some data.
The DataGrid is filled with a collection.
I need that one or more data from one field (or more) of this collection is bound with data from another DataSet (and collection).
I need this binding as DYNAMIC and not STATIC:
if I add a record in the second collection I need this record is avaible in the other collection (DataGrid "collection" before)
Any suggestion?
Edit:
obviously with "if I add" I mean:
if I add one record in the table I need this record in the ComboBox content of the ComboBox field inside the DataGrid filled with the other collection...

Ummm... obviously is not a word I would use there mate.
It's Friday evening and been a tiring week but I'm a bit confused by your explanation.
I'm guessing you're kind of OK with an observablecollection bound to itemssource of your datagrid.
If not bind a.... ditto.
Observablecollection tells you + and - to that collection but not properties.
You have to implement inotifypropertychanged to do that.
Then add some notification from your setters on each property.
kinda like
using GalaSoft.MvvmLight;
namespace wpf1
public class Class1 : ViewModelBase
private int myVar;
public int MyProperty
get
return myVar;
set
myVar = value;
RaisePropertyChanged();
Binding comboboxes in datagrids is tricky.
You have several options.
You mention datasets and collections.
I'm going with collection here.
The thing to realise about the wpf datagrid is datacontext.
The datacontext of the row is an item in the collection the itemscollection is bound to.
If you bind a collection of customer then it's in customer it looks for any binding.
It has to use a bit of weird notation to get to the datacontext of the window.
That's one route to your data.
Another is to have an observable collection as a resource.
