DataGridView, Add Unique Gradient To Each Row

I like to add a gradient brush to each row of my datagridview. I like to change the gradient colors for each row independently depending of some cell values in the row.

I know how to add a solid background color to each, cell, row, column etc. but I do not know how to add a gradient brush to each row individualy.

I need to fill the datagridview with values, the datagridview is disconnected from any database or other data source. After filling the datagridview, I want to step trough each row, find my key values, decide the gradient colors and then add the gradient to the row.

I like to do something similar to what I now do with a background color:

For Each R As DataGridViewRow In DGV.Rows
Dim CS As New DataGridViewCellStyle
Select Case i
