which wpf grid is best in the mentioned scenario

Question

I have to display datas in tabular format in a wpf layout(some grid).
All the column data has to be editable on double click. ALso there will be a Add button on the form, on click of which we have to add a new row to the grid.

Which wpf grid will be the best for this functionality ?
Do you have any sample link??

Thanks a lot.
