Putting A Value In A Cell Via The Column Name When The Column Is Added At Runtime?

I'm trying to create a datagridviewrow and add data to it at runtime. I want the row to have the cells correspond to the columns in a datagridview, so that when I add data to the cells i can call the column name (the columns are likely to change around, so i think the name is better to use then the index).I create the row using the following code:

Dim row As New DataGridViewRow
row.CreateCells(Datagrid)

and the column using the following code:

Dim col As New DataGridViewComboBoxColumn
col.HeaderText = "Reference"
col.Name = "Reference"
datagrid.Columns.Insert(0, col)

I would like to add data to the row via the following code (or something similar that uses the column name instead of the index:

arow.Cells("Reference").Value = Detail.Reference

However at runtime I get the exception Column named Reference cannot be found. Parameter name: columnName I have a sneaking suspicion that the cells cannot be accessed with the column name because the row isnt really attached to columns yet (the row hasnt been added to the datagridview yet. (I tried cloning the cells of a row and then adding them to the row but no success)?
