I have a `Datagridview` with some colmns and some data. Now when I click on a button it changes into Editmode, where the User can change data in some columns. 

The Datagridview itself has alternating row backcolors, but in editmode the editable columns are completely white. To ahieve this I use the following: 

`column1.CellTemplate.Style.BackColor = Color.White;` 

Now when the User finishes editing, the rows have to become like in the beginning. Can someone show me some code how to change the column completely back to default, with alternating row backcolors.  

Some Info: I set the colors in the designer and not in code, so I don't even know how to set alternating backcolor anyway, I started C# only 2 months ago. 

Maybe the solution is very simple, but I have no idea...
