Auto complete with multiple suggestions

[karthik9]

Is it possible to show multiple suggestins (around 5 numbers ) in a combo box during autofill (like google search)

Do you only have a set number of entries that will work successfully?  If so, you might be better off with the dropdown menu you'd create with the enum control.

Otherwise, you'll need to work with event structures to monitor when a key is pressed (value change won't take effect until you leave the control), read what's currently in the control, compare it against a dictionary, create the algorithm to determine what to suggest to fill it in, find a way to make the suggested part appear different, place the cursor where you want it, and put a mechanism in place to remove the old suggestion after each key press.

The time spent putting that together doesn't sound like something where it'd be worth the investment.

Yes, of course its possible. It would be a non-trivial efffort.  Google invested considerable man-hours developing and improving that search feature.  If someone asks you - "Heck, Google does it why can't you?" just quote the the correct time and materials estimate.  Yup Google invests a boat-load of money to do this "simple" thing.  Simple for the users that is... not so simple for the developers but the developers got paid a few years salary each to build that "Simple" feature.

And you want to duplicate that on any scale?  Good job security!  what would you like for take home pay for the next few years?

You can't do this in a combo box (it doesn't show the list when you type), but you can do this by showing a listbox below the text. You can see an example here - http://forums.ni.com/ni/attachments/ni/130/9046/1/Intellisense.llb

Note that this example doesn't do autocomplete, but rather a search, so its algorithm may be different from what you need. You might also have some issue with when to show and hide the listbox, because you don't have focus gained and lost events (in that example, the listbox is just visible all the time because it's a popup).

This might be useful.  It is an example combo box that has auto complete (like QuickDrop) and adds a filter.  It isn't perfect but the idea is you type in some string and it will then populate a dropdown with options that contain what you typed.  So if you type "Br" all the names that contain "Br" will be in the drop down.
