Winforms Combobox and Databinding

Question

I am databinding a combobox to a DataSet, however I want to insert a single item at the top for "None".

Doing:

 combobox.Items.Insert(0,"None");

Doesn't work, as the combobox is now expecting a DataRowView, however DataRowView doesn't have a public constructor, so I can't fake it that way.

Any advice? I'm sure this is a well solved problem.

Answer 1

Insert to the object you are databinding to rather than to the combobox. Good example below.
