Hi, I am looking to create a textbox similar to the Tags textbox in this forum (the one at the bottom when you create a new post). The user should be able to type some text, select an option from the autocomplete dropdown. Selected values are appended with commas and the user can select more than one tags. This is a Winforms application. Any suggestions on how to proceed? Should I create a custom control by extended a textbox?

Thanks
Bala
