change color of DataGrid row

问题

I want to color entire rows of a System.Windows.Forms.DataGrid based on the content of one cell of the Row.
I couldn't find any way to do that, since there is no .Rows-Property of the DataGrid or a .Row-Property of the DataGridTextBoxColumn (or any similar).
Searching for solutions in the internet also didn't help me so far.
Switching to DataGridView is unfortunately not an option.

So the question remains: How can I change the color of a DataGrid row?

Thanks to this link (provided by @Monty) I was able to solve the problem.

You have to format every Cell on its own, so you have to hook up on the SetCellFormat-Event of every Column:

AddHandler column.SetCellFormat, AddressOf FormatGridRow

In the EventHandler you can check for example the cell value of another column of the same row and change the color of the current cell accordingly. When every cell of the row gets formatted this way, it seems like the row as a whole is formatted.

Private Sub FormatGridRow(ByVal sender As Object, ByVal e As DataGridFormatCellEventArgs)
    Dim Cell As DataGridColumnStyle = sender
    Dim ColumnStyles As GridColumnStylesCollection = Cell.DataGridTableStyle.GridColumnStyles
    Dim columnIndex As Integer = ColumnStyles.IndexOf(ColumnStyles.Item("ColumnName"))

    If Cell.DataGridTableTableStyle.DataGrid(e.Row, columnIndex).ToString() = "SomeValue" Then
        e.BackBrush = New SolidBrush(Color.Red)  'this does only change the Cell`s background
    End If
End Sub
