How to set node back colour server-side

[Al]

Hi,

I have a treeview that is built manually (no data-bind) using the metro theme. I'd like to set some node colours to red but neither of the two options below seem to have any effect?

ret.CssClass = "red";

ret.BackColor = Color.Red;

Please ignore this - both methods work just fine it was just my silliness.
