Take the tour ×  I have a Dictionary that contains items and
prices. The items are unique but slowly get added and updated
through the lifetime of the application (that is, I don't know
the item strings in advance). I would like to bind this
structure to a DataGridView, so I can show updates on my Form,
something like:  Dictionary<string, double> _priceData = new
Dictionary<string, double>(); BindingSource _bindingSource = new
BindingSource(); dataGridView1.DataSource = _bindingSource;
_bindingSource.DataSource = _priceData;  But cannot, since
Dictionary does not implement IList (or IListSource,
IBindingList, or IBindingListView).  Is there a way to achieve
this? I need to keep a unique list of items, but also update the
price for an existing item, so a Dictionary is the ideal data
structure I think, but I cannot find a way to display the data
on my Form.   Marc's suggestion below works very nicely, but I'm
still not sure how to update the DataGridView during execution.
I have a class-level variable:  privat
