Can i Have Dropdowns inside the Gridview for a column

Good Day

I am a .Net Developer, Currently we are using ASP.Net Grid view’s, because of the features,etc. we want to Replace existing asp.net grid views with data tables. [ https://datatables.net]

About our Current ASP.Net Grid view: We Use Same Grid view for Rendering Data, and also we allow the user to edit/update the same in the Grid view. [means Grid view is Read and Write]

Please Note in our Grid view we have dropdowns as well. Eg: Gridview/Table Col Name: Currency,

Type is not a textbox, it's a dropdown with the values of (+/- 10 Countries Currency Codes)

What I am expecting in Data Tables/Editor.datatables are

---> it should support dropdowns for columns inside the Grid view

---> it should support Editing/Updating of Gridview.

I Have Tried some sample page using data table. it's working fine without Dropdowns.

So, My Questions are below.

1) Can i Have Dropdowns inside the Gridview for a column (as i mentioned in the above example)

2) Is Data Tables & Editor.datatables are completely free even for commercial purpose.

OR

Only data tables are for free not Editor.datatables

Technologies, we are using:

ASP.Net, c#, HTML, JavaScript, jQuery, AJAX, CSS, WCF Services.
