Can I share the autocomplete code for a textbox for arcobjects to complement my code please.
can you be a bit more precise on what kind of autocompletion do you want to achive? First of all: Autocompletion is a feature of your underlying GUI library. In case you have to deal with Windows Forms, have a look here: https://msdn.microsoft.com/de-de/library/system.windows.forms.textbox.autocompletemode(v=vs.110).aspx
