DataGridView, add unique gradient to each Row

[PeterSchwennesen]

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
         Case 1 : CS.BackColor = Color.Yellow
         Case 2 : CS.BackColor = Color.Blue
    End Select
    R.DefaultCellStyle = CS
Next

Is this possible? And How do you do this?
I am using VB.NET and VS 2008 and 2010

I think you need to create a derived control from the datagridview, and paint this yourself. Perhaps someone else has specifics, but it may give you an idea. Also - search for "custom draw" and "owner drawn" in the contxt of the DataGridView
