> This may help you:
> when creating your datagrid columns, let them inherit from this class and not from the DataGridTextBoxcolumn.
> Now this code will go and check the data of the datagrid cell on the row selected and in my case on the column 1.
> You should chose the percentage column in your case.
>
> Then a check is going to be made on the value of the cell chosen: In my case i have 2 choices
> In your case you should make the switch on the percentage value entered in the cell.
> let the cases be of the type : 0 < value < 10 ..... 10 <= value < 20 ..........

> Automaticaly the colors of all the row cells will change to the color selected.
