how can text property of textblock2's in mvvm. if create property textblock2's text property, wont able bind textblock1's text textblock2.

let me know if want clear question further.

thanks in anticipation.

use 2 properties in vm, , implement equal/override logic there. that's kind of stuff vms in.

vm prop1 <-- binding- textblock1 prop2 <-- binding- textblock2

the prop1 setter implemented such updates prop2 (don't forget inotifypropertychanged), if set prop2 create switch , maintain different value.
