Winform Chat ui as whatsapp

Hello, Shimon,

Please have in mind that RadChat offers only conversational UI. Any specific functionality like sending files and voice notes are a subject of additional custom development that is up to the developer.

RadChat supports toolbar where you can add additional actions that can be performed:

I have researched in general programming forums about recording audio messages:

I believe that you will find them useful.
