Dim stYear, stMake, stModel, stCombined as String

stYear = {get year from datatable}
stMake = {get make from datatable}
stModel = {get model from datatable}

stCombined = stYear + " " + stMake + " " + stModel

Did you application allows you to do it from the data source?  I mean from your query, something like this (assuming you are using SQL Server)

Select OrderDate, Convert(varchar, Year) + '_' + Make + '_' + Model As Year_Make_Model
From yourtable

or you have to do it once the data is in memory?

After you populate you Datatable_1, you can add a Calculated column like this

datatable_1.Columns.Add("Year_Make_Model", GetType(System.String), "Year + ',' + Make + ',' + Model")

And after that you can read the value from the new merge column
