MergeWith Använd metoden för att kombinera formategenskaperna för det angivna Style objektet med formategenskaperna för objektet som den TreeNodeStyle här metoden anropas från.

Note

Metoden MergeWith kopplar stilegenskaperna genom att ange varje egenskap som inte anges i det aktuella TreeNodeStyle objektet med motsvarande värde i det angivna Style objektet. Endast egenskaper som inte har angetts uppdateras. Om en egenskap i det angivna Style objektet inte har angetts ändras inte motsvarande egenskap i det aktuella TreeNodeStyle objektet.
