Can't Change color of controls in DataRepeater

[Blauther]

I have multiple text boxes and combo boxes in a custom control that is used in a datarepeater. At run time, I want to change the backcolor of these text boxes, but I have only managed to change the backcolor of the ones that are selected by the datarepeater. How do I change the backcolor of all the controls in the datarepeater? Any thoughts?
Here is a snippit of the code that I am using:

Public Property Let QuantityBackcolor(ByVal newBackColor As String)
txtQuantity.BackColor = newBackColor
End Property

Thanks in Advance,
