Create a permanent autocomplete textbox in c#?

Question

I am trying to make an autocomplete textbox in c# so I set the AutoCompleteMode to SuggestAppend and set the AutoCompleteSource to custom,

It now works fine every time I start the exe but the problem is that it forgets the history when I close the exe and open it again.....so how can I make its history permanent?

Window form or web Application ? – Shyam sundar shah Jun 19 '13 at 04:26 — Shyam sundar shah, Jun 19 '13 at 04:26

You could use your own AutoCompleteCustomSource .

Catch the TextChanged event, save the new text to a file.

Your AutoCompleteCustomSource should read its values from that file.

You can read more on how to use AutoCompleteCustomSource here:

you have to use all the three properties "AutoCompleteCustomSource", "AutoCompleteMode" and "AutoCompletesource" on TextBox class. then u will get the desired solution.
