Final Color of cell in DataGridView

[DIOS]

VB2005 - I have a DataGridView with cells of various background colors
set with various methods. In the end I want to determine a color for
an individual cell, ie what the user sees. According to MSDN there is
a hierarchy of how the cell gets colored. Is there one function that
will get me the "final" color or do i have to step through the entire
DataGridViewCellStyle Class?

Doesn't this work:

' Set desired color from Color structure
DataGridView1.Item(Column, Row).Style.BackColor = Color

or

DataGridView1.CurrentCell.Style.BackColor = Color

Sure it does. that's not my problem though. Let me restate,
In my processing I color the cells of the DGV using various
methods...rowstyle, cell style, etc.
I present that to the user. Now they click on a cell and i need to
determine the color that they see, the final color of the cell.
Because of the hierarchy of the DataGridViewCellStyle Class simply
using "If CurrentCell.Style.BackColor = Color.Red" will not work.
The cell will be colored red but its another style that set it.
According to MSDN they have a hierarchy of what is used to color the
cell.
My question is rather than cycling through all the class properties to
get to the final color that the user sees is there a super function
that
gives me the final rendered cell color? I'm interested in how to read
the final color of the cell.

I may not have understood your question well because of the word
"final" (what you meant), but my consideration is that you can store
the color in a variable after user selected the color like that:

' Declare myColor as a global variable at class-level
Dim myColor As Color


Handle CellStyleContentChanged Event and inside:

Private Sub DataGridView1_CellStyleChanged _
(ByVal sender As System.Object, ByVal e As
System.Windows.Forms.DataGridViewCellStyleContentChangedEventArgs)
Handles DataGridView1.CellStyleContentChanged

myColor = e.CellStyle.BackColor

End Sub

Retrieve "final" color when you want by means of myColor.
"myColor" gets updated on every raise of CellStyleContentChanged
event. (eg: Msgbox(myColor.toString))

Suppose you have a grid of 1000 x 1000. I don't think you want to save
the color into a variable for each and every cell. simply if I want to
get the color of cell @ row=3, column =5 i was hoping there was a
function that would cycle through all the DataGridViewCellStyle Class
properties to get me the rendered color. Right now in some areas of my
grid I color the entire row with
dgv.Rows(r).DefaultCellStyle.BackColor.= Color.Red. Now If i randomly
pick a cell and use dgvCell.Style.BackColor and it just happens to be
on that row i get a Color.Empty. My dilemma is with so many ways to
color a cell, i need a call that will always give me the color that is
rendered to the user.
