In the code-behind file of the control, try:

this.Style = Resources["ResourceName"] as Style;

What's the difference between FindResource("ResourceName") and Resources["ResourceName"]? – SepehrM Sep 03 '14 at 11:23

With this I could not find the style on a Window's constructor, but with the `FindResource`method I could. (It's an abstract class, inherited in several places and with no defined XAML.) – ANeves Jan 08 '15 at 19:24

I think it's no good idea to do this. If this is really to be done, then I would at least add a comment like: ``in the XAML file. Otherwise I would implement it completely in code behind. – marsh-wiggle Jul 21 '19 at 19:16

Set x:Key in XAML & in code-behind use:

something.Style = (Style) FindResource("YourResourceKey");

Hi we can set style programmatically like this.

Style rowStyle = new Style(typeof(DataGridRow));

DataTrigger dataTrigger = new DataTrigger("TerminalId");
Binding binding = new Binding();
dataTrigger.Binding = binding;
dataTrigger.Value = 72948028;

Setter setter = new Setter(DataGridRow.BackgroundProperty, Brushes.Red);

dataTrigger.Setters.Add(setter);

rowStyle.Triggers.Add(dataTrigger);
listViewUnallocated.RowStyle = rowStyle;
