Infragistics Blog - #Theming

Ignite UI for Angular 22 ships derived themes for the Data Grid - set three color properties on grid-theme() and nested buttons, inputs, chips, and scrollbars realign automatically - plus a dedicated excel-filtering-theme() function and an updated Select dropdown position. Two default changes need attention on upgrade: input type is now box (ng update preserves the old line look), and Select positioning moved to AutoPositionStrategy.
