Cannot add text to RichTextEdit control

[gagar]

I cannot add any text to a RichTextEdit control, I try:

rte_1.SelectTextAll()
rte_1.Clear()

ls_richtext = "Hello"
rtn = rte_1.PasteRTF(ls_richtext)

but nothing is been added to the control.
I try:
rte_1.SelectText(2,1, 0,0) instead of rte_1.SelectTextAll()

rte_1.PasteRTF(ls_richtext, Detail!) instead of
rte_1.PasteRTF(ls_richtext)

but is not working, any help is appreciated.

ls_richtext="Hello" is not a rich text formatted string.

try

ls_richtext = '{\rtf1\ansi\ansicpg1252\deff0\deflang1031{\fonttbl{\f0\fnil\fcharset0 Calibri;}}{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\sa200\sl276\slmult1\lang7\f0\fs22 Hello\par}'
