how to bind different datasource for every datagridviewcomboboxcell

[fanan]

Hi there,
i faced a problem in datagridviewcomboboxcell
i want to bind different data in comboboxcell at every row according to value of cell at the same row
i search the web but all examples depend on the data of the datasource previosly added and didn't depend on the row

This link shows one being populated with simple values, but I would imagine if you looped the results of multiple sources, it would work.

Also, if you use LINQ and combine the sources into one output with a select new {}, you could probably do the same trick without the looping.
