The standard Japanese way to casually request that someone ‘please not’ do something (ないで) is created through the use of the 助動詞（じょどうし） (auxiliary verb) ない, and the 格助詞（かくじょし） (case marking particle) で. This structure may be seen with or without ください added on the end. The 関西弁（かんさいべん） equivalent of this structure is
んといて, which conjugates in the same way as ないで.
ん itself is an abbreviation of ない, while といて is a shortened form of でおいて (the て form of おく, used for conveying that something is being done in advance). This means that
んといて has the same meaning (and stems from) ないでおいて, which can literally be translated as ‘to not do (for some future purpose)’.

-
そういう事（こと）子供（こども）の前（まえ）で言（い）わんといて。

As with the standard Japanese construction, ください may be seen with the Kansai dialect variation, but is not required.

近所（きんじょ）迷惑（めいわく）になるんで鳩（はと）に餌（えさ）をやらんといてください。
Because it is going to inconvenience the neighbors, please don't feed the pigeons.
ておく and ないでおく have roughly similar meanings, despite being opposites. ておく means to do something for the purpose of enabling a future event, while ないでおく means to do something for the purpose of preventing a future event.
