Is using a DataGrid the best way?

Hi,
I've got an application that I'm re-writing in WPF (was in WinForms) and I've hit a bit of a problem.

I have a form where i want the user to be able to enter contact details.
There are 3 fields, contact type (phone, mobile, email etc), contact details (the actualy number) and a notes field.

Once everything has been entered, the user clicks a button to save all of the contact info along with all of the other collected data.

Am I best using a datagrid that the user can directly enter the data into?
or should i be using a different/better method?

And if I'm to be using the grid, then how the hell do i do it?
Its easy in winforms but i cant seem to get my head around it in WPF.

I have created 3 columns and made one a ComboBoxColumn but i cant get it to display anything at all.

Please help!!

Thanks

Read an article or two about MVVM, that helps understanding how you can do this best.
