1 what is the best practice to implement rich text (i decided to use the extended wpf toolkit rich textbox and the edit command in rtb),but what kind of format should i choose: rtf xaml or html ?
2 should i send the document object or the Text property in extended wpf toolkit rich textbox
3 is there any solution for rich textbox for drag drop or inserting images & emotions ?
if anyone had experience on chat app or rich text ,i need your advice
