Your XAML works fine the problem lies withing you getting the Check Box. You should be able to access the element from the Check Box you triggered with the Unchecked or Checked Event.

Example:

var ch = sender as Checkbox;
var row = data_kala.ItemContainerGenerator.ContainerFromItem(ch) as DataGridRow;
bool ischecked = ch.IsChecked;

if (ischecked) {
    row.BackGround = Brushes.Gray;
}
else {
    row.BackGround = Brushes.White;
}
